How Old Are the Vedas?

"Whether the Vedic hymns were composed 1000, or 1500, or 2000, or 3000 years B.C., no power on earth will ever determine." — F. Max Müller, Gifford Lectures, 1890¹

Summary

The Rigveda, the oldest of the four Vedas, was composed in the Punjab after about 1900 BC and before iron came into common use there, about 1200 to 1000 BC.  Most specialists narrow this to about 1500 to 1200 BC.  No Vedic text carries a date, so every figure is an inference.  But independent lines agree:  the gods named in a Hittite-Mitanni treaty of the fourteenth century BC, the horse and spoked chariot, the absence of cities and iron, and the ancient DNA all point to the second millennium BC.  The hymns were then kept by memory for well over two thousand years.  The oldest known Veda manuscripts date from about AD 1150.

What the tradition claims.  The classical schools give the Vedas no date at all.  Mīmāṃsā and Vedānta hold them apauruṣeya, "not made by a person", because no author is remembered.²³  Swami Dayananda, founder of the Arya Samaj, computed that God revealed them 1,960,852,976 years before his own day.⁴  The popular "5,000 years" comes from the Purāṇic account that Vyāsa arranged the one Veda into four at the end of the age before the Kali age, which astronomers began in 3102 BC.⁵⁶  These are statements of doctrine, and this article does not try to refute doctrine.  It tests the claims that rest on evidence.

The early dates.  The Out-of-India writers argue that the Vedic people were native to India and the Rigveda far older than 1500 BC.  Shrikant Talageri dates its oldest books to 3400-2600 BC and its latest to 2200-1400 BC.⁷  B. G. Tilak in 1893 put the hymns "not later than 4000 B.C." from the stars named in the Vedic calendar.⁸  Subhash Kak dates a Śatapatha Brāhmaṇa statement about the Pleiades to 2950 BC.⁹  Kak's arithmetic checks out.  But the statement is in a later prose text that knows iron, and its date shifts by eight centuries with an assumption the text does not state.¹⁰

Why about 1500 to 1200 BC.  The date began as guesswork.  Max Müller in 1859 allowed about 200 years for each layer of Vedic literature, and in 1890 he said no one could ever fix the date.¹¹¹  It has since been rebuilt from evidence.  A treaty of the mid-fourteenth century BC between the Hittite king and a king of Mitanni in Syria invokes Mitra, Varuṇa, Indra and the Nāsatyas, gods of the Rigveda, and the Mitanni's Indo-Aryan words are slightly older in form than the Rigveda's.¹²¹³  The Rigveda is full of horses and chariots;  the first spoke-wheeled chariots appear on the steppe east of the Urals about 2000 BC.¹⁴  It knows copper and bronze but not iron, and forts but not cities.¹⁵¹⁵  Michael Witzel of Harvard, a leading critic of the early dates, says plainly that "there still is no absolute dating of any Ved. text."¹³  The iron bound is the weakest, since iron was worked in the Ganges plain earlier than once thought;  the lower bounds are the strong ones.¹⁶

The genetic evidence.  The largest ancient-DNA study of South Asia, by Vagheesh Narasimhan, David Reich and their colleagues in 2019, sequenced 523 ancient people.  It found that ancestry from Bronze Age steppe pastoralists entered northern South Asia between about 1900 and 1500 BC, came mostly through men, and is highest today in Brahmin groups, the hereditary keepers of the Vedas.¹⁷¹⁷  The one genome yet read from an Indus city, a woman buried at Rakhigarhi about 2800-2300 BC, carries none of it.¹⁸  Genes are not languages, as Talageri rightly insists.¹⁹  But this is the pattern expected if Indo-Aryan speech arrived from the northwest in the second millennium BC, and it is hard to reconcile with a Rigveda composed by the Indus people before 2500 BC.

The Sarasvati.  The Rigveda praises the Sarasvatī as flowing "from mountains to the ocean".²⁰  Out-of-India writers identify it with the dry Ghaggar-Hakra channel and argue that the hymns must be older than its drying.  The geology is disputed.  The study most favourable to them, by Anirban Chatterjee and colleagues, finds Himalayan water in the channel until about 4.5 ka, but "by the time the civilization matured, the river had already lost its glacial connection".²¹  Other teams date the Himalayan river's departure thousands of years earlier, and the only evidence of such a river reaching the sea is from before 10 ka.²²²³  Read literally, the hymn would date Book 7 too early even for Talageri.  The river cannot fix the date either way.

When the Vedas were written down.  About AD 1030 the Persian scholar al-Bīrūnī reported that the Brahmins "do not allow the Veda to be committed to writing", and that a Kashmiri named Vasukra had only recently written it down.²⁴  Claims that the Vedas were "written 5000 years ago" contradict the tradition's own practice.²⁵  The oral tradition is a genuinely strong preservation method:  it has kept even the pitch accents of a long-dead pronunciation.¹³  But it was not flawless.  About 10,000 mantras differ between the Vedic schools, and the editors who catalogued them blamed "faults of memory" for much of it.²⁶²⁶  By the same test applied to the Bible, the gap from composition to the oldest copy is over 2,300 years for the Rigveda, about 400 to 600 years for Isaiah, and under 150 years for the Gospels.

The Bible's chronology.  A Rigveda of about 1500 to 1200 BC fits after the Flood and Babel on every biblical chronology.  Talageri's 3400 BC would fall before the Flood on all three, and Tilak's "not later than 4000 B.C." at about the Creation on Ussher's count.  Those dates fail here on the evidence, not on the Bible.  The harder problem for a young-earth reader is not the Vedas but the Indus civilisation, whose conventional dates begin before the Masoretic Flood.

Part 1: What the tradition says

Hindu tradition does not speak with one voice about the age of the Vedas, and its main positions are not dates at all.  Each is stated here from its classical source before anything is tested.

The Vedas as authorless

The Mīmāṃsā school, the classical science of interpreting the Veda, holds that the Veda was never composed.  Its classical commentator Śabara, writing on Jaimini's Mīmāṃsā Sūtra, argues from memory.  A person who invented the link between a word and its meaning "would surely be remembered at the time of using the word", as Pāṇini is remembered by anyone who uses his grammatical terms.³  No such person is remembered.  So, Śabara concludes, "no person created the relations (of words) and then for the purpose of making use of them, composed the Vedas."³

Śabara knew the obvious objection.  The Veda mentions mortal men, such as "Babara, the son of Pravahana", who must have lived before any text that names him.³  His answer is that babara is "only a word imitative of sound (produced by the blowing wind)", and prāvāhaṇi means "one who carries things in an excellent manner".³  Texts named after men, such as the Kāṭhaka, are named after famous teachers, not authors.

Vedānta, the school of the Upaniṣads, adopts the same ground.  The Brahmasūtra says that "there follows the eternity of the Veda", and its great commentator Śaṅkara explains that this eternity "is founded on the absence of the remembrance of an agent".²  On this view the world is dissolved and remade in endless cycles, and in each one the seers find the same Veda again.  Śaṅkara quotes a verse he credits to Vyāsa:  the great seers "obtained, through their penance, the Vedas together with the itihasas, which had been hidden at the end of the yuga."²

On this teaching the Vedas have no date of composition, because they were not composed.  That is a religious claim, and a historian cannot test it directly.  What can be tested is its premise:  that the hymns show no human authors.  The hymns themselves do not read that way.  The very first hymn says Agni is "to be praised by living as by ancient seers", distinguishing earlier poets from present ones.²⁰  In the seventh book the poet Vasiṣṭha names himself, and describes a battle on the Paruṣṇī river won for a named king, Sudās.²⁰  These are the marks of poems made by men for patrons.  The hymns also speak of sacred speech as something found rather than made:  one says that Vāk, Speech, was found "harbouring within the Ṛṣis", the seers.²⁰  Both readings are in the text.  Śabara's reply shows the tradition saw the problem and answered it by reinterpreting the names.

Revealed at the creation

Swami Dayananda Saraswati, who founded the reforming Arya Samaj, kept the Vedas' divine origin but gave it a date.  "The Vedas having been revealed by God who has no bodily organs, no one ever saw them being composed".⁴  God revealed them through four seers, Agni, Vāyu, Āditya and Aṅgiras, at the beginning of the present creation.  Dayananda's answer to "How many years have elapsed since the revelation of the Vedas" is 1,960,852,976 years, reached by adding up the world ages of the Manu-smṛti.  His translator adds that Pandit Lekhram later corrected the sum to 1,955,884,976.⁴  This is a cosmological figure, not a historical one.  Its basis, the cycle of world ages, is examined in Hindu Cosmology and Vedic Science Claims.

Vyāsa and the "five thousand years"

The figure most often heard is that the Vedas are about 5,000 years old.  It comes from the Purāṇas, which say that in every third age of the world Viṣṇu, as the sage Vyāsa, "divides the Veda, which is (properly, but) one, into many portions", and "makes the Veda fourfold, to adapt it to their capacities".⁵  The Viṣṇu Purāṇa says this has happened twenty-eight times in the present age of Manu.⁵  The current Vyāsa did his work at the end of the third age, just before the Kali age began, and the astronomers set that beginning at 3102 BC.  The earliest datable use of that epoch is the astronomer Āryabhaṭa, who wrote that he was 23 years old "When three yugapadas and sixty times sixty years had elapsed", which gives AD 499 only "If Aryabhata began the Kaliyuga at 3102 b.c. as later astronomers did".⁶  So the "5,000 years" is the date of Vyāsa's arrangement on a reckoning first attested about 3,600 years after the date it names.  On the tradition's own terms the Veda existed long before Vyāsa.  Al-Bīrūnī heard the same account from Brahmins about AD 1030:  the Veda "had been obliterated in the last Dvapara-yuga ... until it was renewed by Vyasa, the son of Parasara."²⁴

Modern statements repeat the figure and sometimes enlarge it.  A. C. Bhaktivedanta Swami Prabhupada, founder of the Hare Krishna movement, wrote that "five thousand years ago Vyāsadeva put the Vedas in writing for the people in this age, Kali-yuga."²⁷  India's Prime Minister's Office summarised a speech of 2017 as being "about the Vedas written 5000 years ago".²⁵  The astronomer B. G. Sidharth's 1999 book The Celestial Key to the Vedas is sold on the claim that he "proves conclusively that the earliest portions of the Rig Veda can be dated as far back as 10,000 b.c."²⁸  The first two say the Vedas were written 5,000 years ago, which is a testable claim, and Part 6 tests it.

These three positions are doctrines, held on the authority of revelation and tradition.  None of them claims to rest on archaeology, linguistics or genetics, and none is refuted by showing that a hymn was composed in a given century.  A believer can hold that the eternal Veda was heard by seers in the second millennium BC.  The positions that do claim evidence are the next part's subject.

Part 2: The case for a much older Rigveda

The Out-of-India or "indigenous Aryan" thesis holds that the people of the Rigveda were native to India, that the Indo-European languages spread outward from India rather than into it, and that the hymns are older than the decline of the Indus cities about 1900 BC.  Its defenders include Shrikant Talageri, Koenraad Elst, the archaeologist B. B. Lal and Subhash Kak.  They argue from three kinds of evidence:  the order of the hymns and the names in the Mitanni treaties, the Sarasvati river, and astronomy.

Talageri's chronology

Talageri gives the most detailed early chronology.  In 2009, after "my (till then) tentative, and intuitive, estimate" of a start in the fourth millennium BC, he set out what he called "my final dates (which I will still call a conservative estimate)":⁷

His reasons are internal and comparative.  He orders the ten books by their composers' families, the kings they name and the rivers they know.  He then notes that the Indo-Aryan personal names known from the Mitanni kingdom of Syria share elements with names in the late books but not the early ones:  "Not a single MT name is found in the Early Books (6,3,7)."⁷  Since the Mitanni names are attested by about 1400 BC, he argues that the late books were already current then, and the early books centuries earlier.  "The Mitanni evidence is crucial in providing us with a sheet-anchor for fixing the absolute chronology of the Rigveda".⁷  His second reason is the Sarasvati, which he says "had almost dried up by the mid-second millennium BCE itself, and that, long before that, it was a mighty river, mightier than the Indus".⁷

The Mitanni argument is Talageri's strongest, because it uses evidence his opponents accept.  But it shows less than he needs.  Shared name-elements show that the late books and the Mitanni drew on a common Indo-Aryan naming stock.  They do not show which is older, or by how much.  Michael Witzel reads the same evidence the other way:  the Mitanni words keep older sound forms than the Rigveda's, such as aika for Vedic eka, "one".¹⁵  A conservative dialect can keep old forms, so this is not decisive either.  The weightier problem is the spread.  Witzel's objection is that "When tabled, the various family books in his reconstruction turn out to be spread out over two thousand years, well before the invention of the horse-drawn chariot."¹⁵  Book 7, which Talageri puts at 3400-2600 BC, already has warriors with "harnessed horses" at the Battle of the Ten Kings.²⁰  Whether horses and chariots could be in the Punjab that early is taken up in Part 5.

The astronomers

The astronomical datings are older than the Out-of-India thesis and do not depend on it.  In 1893 the Indian scholar and nationalist B. G. Tilak argued that the Vedic calendar remembers a time when the spring equinox lay in the constellation Orion:  "the traditions recorded in the Rigveda unmistakably point to a period not later than 4000 B.C."⁸  He divided Vedic history into a pre-Orion period of 6000-4000 BC, an Orion period of 4000-2500 BC, and a Kṛttikā or Pleiades period of 2500-1400 BC.⁸  The 4500 BC often credited to Tilak is not in his book.  It comes from the German Indologist Hermann Jacobi, who reached a similar result independently in 1894.  But Jacobi did not date the Rigveda itself to 4500 BC:  "We can hardly venture, it is true, to place the Rig-Veda so far back, but only the beginnings of the civilization".²⁹  Georg Bühler of Vienna, who supported the new method, drew the limit in the same year.  The astronomy, he wrote, "does not prove that any verse or line of the Vedas was composed in those remote times".³⁰

Subhash Kak revived the method.  His date for the Rigveda rests chiefly on the Sarasvati:  the hymns, he writes, "are generally anterior to 1900 BCE".³¹  His best-known astronomical point is from Śatapatha Brāhmaṇa 2.1.2.3, which says the Pleiades "never swerve from the east".  Kak:  "This corresponds to 2950 BC."⁹

That number can be checked, and it is right.  The Pleiades rose exactly due east when they stood on the celestial equator, and precession put them there about 2916 BC, within the error of the method.¹⁰  If "due east" means within one degree, the window is about 3100-2740 BC.  In 1000 BC they rose about twelve degrees north of east.  So a strict reading of the sentence does fit the third millennium BC better than the first.  That is a fair point for the early-date side, and the mainstream answer to it is not arithmetic but interpretation.

Three things keep it from dating the Rigveda.  First, the sentence is in a Brāhmaṇa, a prose ritual text that quotes the Rigveda and is later than it, so even at face value it dates neither the hymns nor their language.  Second, the same Brāhmaṇa knows iron.  Witzel:  "we simply cannot date the ŚB in the third millennium BCE, as it has strong evidence of iron which emerged in India only by 1200/1000 BCE".¹⁵  If the sentence is old, it is an inherited observation, which dates the observation and not the text, exactly Bühler's limit.  Witzel's rule is that because texts keep old memories, "we can only date them by their latest, not their earliest datable features."¹⁵  Third, the result depends on an assumption the text does not state.  The Pleiades are faint and cannot be seen at the moment of rising.  If an observer judged "due east" when they stood five degrees up, the date becomes about 2500 BC;  at ten degrees, about 2090 BC.¹⁰  An unstated choice moves the answer by eight centuries.

Other early-date writers

The other leading defenders of an early date build on the same two pillars, the Sarasvati and the astronomy.  B. B. Lal, who excavated the Harappan town of Kalibangan in the 1960s, argues from the river:  "Since during the days of the Rigveda the Sarasvati was a mighty flowing river, it becomes self-evident that the Rigveda is anterior to 2,000 BCE. How much earlier is anybody's guess."  He thinks it "not unlikely that the earliest Mandalas may have been composed sometime in the 4th millennium BCE".³²  Koenraad Elst takes his figure from Tilak:  the Vedic texts "mention constellations on the equinox points which were there from 4,000 BC for the Rg-Veda".³³  David Frawley, also known as Vamadeva Shastri, gives the widest range, with an "early Rig Vedic" layer at "6500-3100 BC, Pre-Harappan".³⁴  Nicholas Kazanas's 2009 book is described by its publisher as showing that "the bulk of the Rgveda hymns appear to have been composed in the Fourth Millennium".³⁵  None of these adds an independent kind of evidence to the ones tested in this article.

Part 3: The case for about 1500 to 1200 BC

How the date began

The textbook date started as an estimate, and its author said so.  In 1859 Max Müller divided Vedic literature into four layers and counted back from the Buddha.  He allowed 200 years each to the two oldest layers, putting the hymns at 1200-1000 BC, and admitted that even this assumed "that during the early periods of history the growth of the human mind was more luxuriant than in later times".¹¹  By 1890 he reported "a general agreement among Sanskrit scholars that the Vedic hymns ... were composed between 1500 and 1000 B.C.", but warned that the date "is and will always remain hypothetical".¹  Then came the sentence quoted at the head of this article:  no power on earth would ever fix the date.¹

Early-date writers often quote Müller's admission as if it settled the matter.  Jacobi in 1894 called the layer-counting "a somewhat subjective guess at their duration", and he was right about the 1859 method.²⁹  But the date did not stay where Müller left it.  It is now supported by evidence he did not have, and it is that evidence that has to be weighed.

The reasons as they now stand

Witzel's summary is the clearest statement of the mainstream case, and he begins with its limit:  "there still is no absolute dating of any Ved. text."¹³  What exists instead is a relative order and a set of bounds.

The order of the texts.  The Vedic texts quote one another, so their order is fixed even where their dates are not.  The Rigveda comes first.  The Atharvaveda, which is later, is the first to mention iron.  The prose Brāhmaṇas follow, then the early Upaniṣads.  The Buddha, about 500 or 400 BC, "postdates almost all Vedic texts", and the grammarian Pāṇini, before Patañjali about 150 BC, quotes most of them.¹³  That puts the end of the Vedic period about 500-400 BC and leaves a long sequence of texts before it.

The earliest possible date.  The Rigveda "does not know of large cities such as that of the Indus civilization but only of ruins ... and of small forts", so Witzel puts it after the Indus cities broke up, about 1900 BC.¹⁵  Its world is full of horses, horse-drawn chariots and chariot racing, which "do not fit at all with such early dates for the RV ... and rather put it after c. 2000 BCE".¹⁵  Witzel calls 1900 BC "Maximally, but unlikely".¹⁵  The chariot date comes from the steppe east of the Urals.  At Sintashta, David Anthony reports, radiocarbon showed the remains to be "the oldest chariots known anywhere", and a chariot grave at Krivoe Ozero with "spoked wheel impressions" is "dated about 2000 BCE".¹⁴

The latest possible date.  The Rigveda "does not yet know of iron but only of the hard metal copper/bronze";  its word ayas is cognate with Avestan aiiah, "copper/bronze".  Iron appears in later Vedic texts as the "black metal", and in South Asia "only by c. 1200 or 1000 BCE", so "the RV must be earlier than that."¹⁵  Griffith's 1896 translation, still widely read, renders ayas as "iron", as in "our fort of iron" at RV 7.95.1, and so can lead a reader to find iron in the Rigveda where the Sanskrit has only metal.²⁰

The Mitanni treaty.  About the mid-fourteenth century BC the Hittite king Šuppiluliuma I made a treaty with Šattiwaza, a son of the murdered Mitanni king Tušratta who had fled to the Hittite court.  Mitanni lay in northern Syria.¹²  Among the gods called to witness for Mitanni are "the Mitra-gods, the Varuna-gods, Indra, the Nasatya-gods".¹²  These are four gods of the Rigveda.  Other Mitanni sources use Indo-Aryan words for horses, chariots and chariot racing, including the numerals aika, tera, panza, satta and na, meaning one, three, five, seven and nine, and the king's own name Tušratta matches the Rigvedic tveṣaratha, "having a vehement chariot".¹⁵  Witzel puts the Rigveda "more or less contemporary with the Mitanni texts of northern Syria/Iraq (1450-1350 BCE)", since their Indo-Aryan forms "slightly predate the Rgveda".¹³

A short span.  Witzel adds that "most hymns were composed over a span of just five generations, under the Puru and Bharata chieftains, notably the great Bharata king Sudas".¹³  On his reading the bulk of the Rigveda took perhaps 150 years.  Talageri's internal chronology needs "a period of at least two millenniums".³⁶

Put together, these give a window of about 1900 to 1000 BC for the hymns.  Specialists place them toward the middle.  Anthony:  "Most Vedic specialists agree that the 1,028 hymns of the Rig Veda were compiled into what became the sacred form in the Punjab ... probably between about 1500 and 1300 BCE."¹⁴  The Indologist Asko Parpola dates the arrival of the Rigvedic tribes in northwestern South Asia to "c. 1400-1200 BCE", which he says "agrees with the estimated date most often proposed by others."³⁷

How strong each reason is

Not every reason is equally strong, and a fair reader should know which ones carry the weight.

1. The relative order is solid. Texts that quote the Rigveda are later than it. No one on either side disputes the order of the main layers, only their absolute ages and lengths.
2. The Mitanni evidence is solid but indirect. It proves that Indo-Aryan speakers who worshipped Mitra, Varuṇa, Indra and the Nāsatyas were in Syria by the fourteenth century BC. It does not date a single hymn. Witzel's argument that the Mitanni forms are older than the Rigveda's is linguistic and reasonable, but a conservative dialect could keep old forms. Talageri reads the same evidence as a sign that the late books were already current. Both readings fit a Rigveda in the second millennium BC. Neither fits one in the fourth.
3. The iron bound is the weakest. Witzel himself notes that "dates for iron had been creeping up over the last few decades".¹⁵ In 2003 the archaeologist Rakesh Tewari reported "iron artefacts, furnaces, tuyeres and slag in layers radiocarbon dated between 1800 and 1000 BC" in the Ganges plain.¹⁶ If iron was worked there that early, the upper bound loosens, though the Rigveda's own country is the Punjab, further west. But loosening an upper bound does not push the Rigveda earlier; it only removes a reason to keep it late.
4. The lower bounds are the ones that matter for the early dates. The absence of cities, and the horse and chariot, are what rule out a Rigveda in the fourth or third millennium BC. These are tested in Parts 4 and 5.

Edwin Bryant's survey of the whole debate is a fair measure of where this leaves things.  He calls the Mitanni evidence "one of the few happy occasions when archaeology and linguistics coincide unambiguously".³⁸  But on the purely linguistic and textual arguments for the date he is agnostic:  they "are not sufficiently solid to convince even a majority of the parties in this debate of either an earlier or a later date."³⁸  His conclusion sets out the migration account, which "still has much to recommend itself", and says the indigenous position "can by no means carry the day" but "at least merits a serious response."³⁸  Since 2001 the decisive new evidence has come from neither philology nor astronomy, but from ancient DNA.

Part 4: What the ancient DNA shows

Genes do not speak languages, and every author cited here says so.  A population can change its language without changing its ancestry, and the reverse.  What ancient DNA can do is say who moved where and when, and whether that pattern fits one account of the language's arrival better than another.

The studies

Reich and colleagues, 2009.  The first large study of Indian genomes found that most Indians descend from a mixture of two ancient populations.  The "Ancestral North Indians" were related to people of the Middle East, Central Asia and Europe;  the "Ancestral South Indians" were not.  The northern share "is higher in traditionally upper caste and Indo-European speakers."  The authors found it "tempting to hypothesize" that the northern ancestors spoke Proto-Indo-European, "although we cannot be certain without a date for ANI-ASI mixture."³⁹

Moorjani and colleagues, 2013, supplied the date.  From the length of mixed stretches of DNA in 73 Indian groups they dated the mixture to "about 1,900 to 4,200 years ago", after which India shifted "to endogamy", marriage within closed groups.⁴⁰  The Indo-European-speaking groups gave younger dates than the Dravidian-speaking ones, which the authors explain as a second wave of mixture in the north.

Narasimhan, Reich and colleagues, 2019, is the study that changed the debate.  It added the genomes of 523 ancient people from South and Central Asia.  Its main findings:

1. Before about 2000 BC the people around the Indus world, known from eleven individuals buried at trading sites in Turkmenistan and eastern Iran, had "no detectable Steppe ancestry".¹⁷
2. Steppe ancestry first appears in Central Asia "by the turn of the second millennium BCE" and then "integrated further south in the first half of the second millennium BCE, contributing up to 30% of the ancestry of modern groups in South Asia."¹⁷
3. In ancient people of the Swat valley in northern Pakistan, the mixing date is "on average 26 generations before the date that they lived, corresponding to a 95% confidence interval of ~1900–1500 BCE."¹⁷
4. In modern South Asians this ancestry came mostly through men, as an earlier study of Y chromosomes by Marina Silva and colleagues had also found: the Bronze Age influx from Central Asia "was strongly male-driven".⁴¹
5. It is highest in groups of "traditionally priestly status". Of the six groups with the most excess steppe ancestry, five were Brahmins or Bhumihars, though such groups were only 7-11% of the 140 analysed. The authors add that "this is not a formal test".¹⁷
6. The steppe ancestry in South Asia "has the same profile as that in Bronze Age Eastern Europe", where an earlier movement from the steppe took place early in the third millennium BC.¹⁷

Shinde and colleagues, 2019, reported the first genome from an Indus city.  The team sampled 61 skeletons from the cemetery at Rakhigarhi in Haryana.  One, a woman, yielded usable DNA, covering 31,760 genetic markers after the damaged sequences were screened.  The bones could not be radiocarbon dated, and the burial is dated by its Harappan pottery and by charcoal from the town, "spanning 2800–2300 BCE".¹⁸  She fits the same mixture as the eleven Indus-related individuals and carries no steppe ancestry.  The authors are explicit about the limits:  "a single sample--or even the gradient of 12 likely IVC samples we have identified--cannot fully characterize a cosmopolitan ancient civilization."¹⁸  On language they conclude that "a natural route for Indo-European languages to have spread into South Asia is from Eastern Europe via Central Asia", in the first half of the second millennium BC.¹⁸

Later work confirms the pattern without dating it more closely.  A 2025 study of 2,762 modern Indian genomes by Elise Kerdoncuff, Priya Moorjani and colleagues finds steppe-related ancestry "between ~0% and 45%" in individuals, modelled on steppe populations "dated to ~2,000–900 BCE".⁴²  Iosif Lazaridis, Reich and colleagues traced the Indo-European languages to the Yamnaya people of the steppe and the Indo-Iranian branch through the Sintashta culture, though their study has no South Asian genomes.⁴³

What the studies did not find

No ancient genome has yet been published from Harappa, Mohenjo-daro, the Ganges plain or the Punjab of the Vedic period.  The Rakhigarhi woman is one person without a direct date.  The eleven Indus-related individuals were buried outside India.  The Swat valley people are the nearest to the Vedic homeland, and they lived from about 1200 BC onward, at the northwest edge of it.  Narasimhan's team also admits that "there are so few material culture similarities between the central Steppe and South Asia" that "some archaeologists recognize no evidence of a connection".¹⁷  Any reader who wants to keep an open mind has real gaps to point to.

What the studies mean for the date

The genetic pattern fits the mainstream account closely.  The account needs Indo-Aryan speakers to reach the northwest between about 2000 and 1500 BC, from the steppe through Central Asia, and to be remembered in the priestly lineages that kept their hymns.  That is when steppe ancestry arrives, where it comes from, through whom it comes, and in whom it is concentrated today.

The early-date account fits less well.  It needs the Rigveda's Sanskrit to be spoken in the Punjab and Haryana before 2500 BC, by people like the Rakhigarhi woman who had no steppe ancestry.  It then has to explain why the castes that preserved the hymns carry more of an ancestry that arrived a thousand years later.  The genetic direction is also against it.  Steppe ancestry is in Eastern Europe early in the third millennium BC, in Central Asia about 2000 BC and in South Asia after that.  That is the trail of a movement into India, not out of it.

How the defenders of an early date answer

The answers divide in two.  Vasant Shinde, the Rakhigarhi paper's archaeologist and first author, told the press that "the Harappans were the Vedic people", that the research "completely sets aside the Aryan Migration/Invasion Theory", and that the Vedic culture "was developed by the indigenous people of South Asia."⁴⁴  None of this is in the paper, which does not mention the Vedas and which proposes the steppe route for Indo-European.  Narasimhan, a co-author of both papers, answered that the arriving steppe people "clearly adopted local cultural practices, which we call today Vedic culture", and that the steppe ancestry "must have come later".⁴⁵

Talageri, to his credit, did not defend the press statements.  He wrote that the papers contain "clear statements in support of the theory that Indo-European languages originated in the Steppes", and that on the scientists' contradictory public positions "I cannot contest the criticism".¹⁹  His answer is a different one, and it is the strongest available:  that the claim that the Harappans did not speak Indo-European "cannot be proved by any amount of genetic data and quibbling, and can only be proved by conclusively disproving my case for the composition of the Old Rigveda before 2500 BCE".¹⁹

He is right that genes do not prove language.  But the argument also works the other way.  If the genetic evidence cannot decide the language, his case must stand on the Rigveda's internal chronology, the Mitanni names, the Sarasvati and the absence of horses and chariots in the record, and those were weighed in Parts 2, 3 and 5.  The genetics add a pattern that his account must explain and the mainstream account predicts.  That does not prove the mainstream date, but it is the kind of independent check that a date resting on texts alone rarely gets.

Part 5: The Sarasvati, the horse and the chariot

The river

The Rigveda praises the Sarasvatī as a great river, "Pure in her course from mountains to the ocean".²⁰  In the river hymn of the tenth book it is named between the Yamunā and the Śutudrī, the Sutlej, which places it where the dry Ghaggar-Hakra channel now runs between them.²⁰  That identification is reasonable, and it is a point for the Out-of-India side.  Their argument is that the hymns describe this river at its height, and so must be older than its drying.  Kak puts the drying "around 1900 BCE" and the hymns "generally anterior" to it;  Talageri says it was "a mighty river, mightier than the Indus" long before the mid-second millennium BC.³¹⁷  The argument is not only theirs.  In 1995 Witzel himself wrote that the "mountains to the sea" description "would put the battle of ten kings prior to 1500 BC or so", as Talageri points out.⁷

The geology has moved since then, and it is now the test.  Five studies bear on it.

1. Clift and colleagues, 2012, dated the zircon grains in the buried channel sands. The Yamuna, which once fed the system, left "as early as 49 ka and no later than 10 ka", that is between about 49,000 and 10,000 years ago, and the change "significantly predated" the collapse of the Harappan cities. The channels themselves "were active until after 4.5 ka".⁴⁶
2. Singh and colleagues, 2017, dated sand grains by luminescence and found that the Sutlej's flow in this channel "terminated considerably earlier than Indus occupation, with diversion to its present course complete shortly after ~8 ka". "Indus urban settlements thus developed along an abandoned river valley rather than an active Himalayan river."²²
3. Giosan and colleagues, 2012, mapped the whole Harappan plain and found that "only monsoonal-fed rivers were active there during the Holocene", rivers fed by rain rather than glaciers. Those rivers were real and "undoubtedly active in this region during the Urban Harappan Phase".⁴⁷
4. Chatterjee and colleagues, 2019, the strongest study for the early-date side, traced Himalayan sediment in the Ghaggar's deposits: "during 80-20 ka and 9-4.5 ka the river was perennial and was receiving sediments from the Higher and Lesser Himalayas", fed by branches of the Sutlej. They write that this river "can be correlated with the Saraswati". But they add: "by the time the civilization matured, the river had already lost its glacial connection."²¹
5. Khonde and colleagues, 2017, cored the Great Rann of Kachchh, where such a river would have met the sea. They found that "a large Himalayan or Sub-Himalayan Saraswati-like river may have discharged into the Arabian Sea until 10 ka", and that their method could not detect a smaller river after that.²³

The geologists disagree about when the Himalayan water left the channel:  about 8,000 years ago on Singh's dating, about 4,500 on Chatterjee's.  On the conventional calendar, 4.5 ka is about 2500 BC.⁴⁸  Even on Chatterjee's reading, the most favourable to the early dates, the glacier-fed river was gone before the Indus cities reached their height.  And the only evidence of such a river reaching the sea, as the hymn says, is from before 10 ka, some 8,000 years before Christ.  Read literally, then, the Sarasvati hymn proves too much:  it would date Book 7 to a time thousands of years before Talageri's own 3400 BC.

The more modest reading is that the hymn proves very little either way.  Poets praise rivers, and a hymn's "mountains to the ocean" is not a measured discharge.  A Rigveda of 1500-1200 BC sung beside a shrunken, monsoon-fed Ghaggar is possible;  so is a Rigveda of 3000 BC sung beside Chatterjee's Sutlej-fed one.  The Sarasvati cannot carry the weight the early-date argument puts on it, and it is not strong evidence for the mainstream date either.

The horse and the chariot

The Rigveda's world is a horse world.  Its gods ride chariots, its patrons give horses, and its battles are fought from chariots, including the Battle of the Ten Kings in Book 7.²⁰  That makes the horse a test of any early date.

The horse-drawn chariot with spoked wheels was invented on the steppe east of the Urals.  Anthony dates the oldest chariot graves at Sintashta and Krivoe Ozero to about 2000 BC.¹⁴  A 2021 study of 273 ancient horse genomes led by Pablo Librado and Ludovic Orlando found that the ancestors of all modern domestic horses spread from the western steppe "from about 2000 bc, synchronously with equestrian material culture, including Sintashta spoke-wheeled chariots".  In Asia, unlike Europe, "Indo-Iranian languages, chariots and horses spread together, following the early second millennium bc Sintashta culture."⁴⁹

In the Indus cities themselves, the horse is all but absent.  Witzel, citing the zooarchaeologist Richard Meadow, writes that "not one clear example of horse bones exists in the Indus excavations and elsewhere in North India before c. 1700 BCE", and that the bones claimed from Surkotada in Gujarat belong to wild asses, "not to true horses".¹⁵  His 2000 article with Steve Farmer, citing the same work, gives "before c. 2000 BCE";  the primary study by Meadow and Ajita Patel was not available for this article.⁵⁰  Both figures fall at or after the end of the Indus cities' prime, about 1900 BC.

The most famous counter-claim was a forgery.  In 2000 N. S. Rajaram and N. Jha published a "horse seal" from Mohenjo-daro in The Deciphered Indus Script.  Witzel and Farmer showed that it was "a computer distortion of a broken 'unicorn bull' seal", the commonest seal type at the site.⁵⁰  The chariots announced in 2018 from Sanauli near Delhi, dated by their excavators to about 1900 BC, are a real find and a remarkable one.  But the excavators' own report describes their "solid wheels", and it does not say what animal drew them.⁵¹  A solid-wheeled vehicle is not the spoked chariot of the Rigveda, and nothing at Sanauli shows a horse.

This is an argument from absence, and absence can be overturned by one good find.  But it is a strong argument here, because the Indus sites have been dug for a century, and the evidence that has turned up, from the steppe chariot graves to the horse genomes, points the same way.  A horse-and-chariot Rigveda fits the second millennium BC.  In the fourth millennium it would describe animals and vehicles that did not yet exist anywhere.

Part 6: When the Vedas were written down

Oral for more than two thousand years

The Vedas were composed and handed down without writing.  Witzel:  "The Vedic texts were orally composed and transmitted, without the use of script, in an unbroken line of transmission from teacher to student that was formalized early on."¹³  Reciters are taught from childhood techniques that, in UNESCO's description, rest on "tonal accents, a unique manner of pronouncing each letter and specific speech combinations".⁵²  For the Rigveda the key step was the padapāṭha, a word-by-word version composed by the grammarian Śākalya in the late Brāhmaṇa period, which fixed the text his school has kept since.⁵³  The tradition's own indexes, the Anukramaṇīs, list for each hymn "the names of the authors and the deities, and the metres", and, as Max Müller pointed out, they already presuppose the ten books of the Rigveda "in all its important features exactly such as we now possess it".¹

The earliest outside witness is al-Bīrūnī, writing about AD 1030:  "They do not allow the Veda to be committed to writing, because it is recited according to certain modulations, and they therefore avoid the use of the pen, since it is liable to cause some error, and may occasion an addition or a defect in the written text."  He adds that "not long before our time" a Kashmiri Brahmin named Vasukra had undertaken "the task of explaining the Veda and committing it to writing", because he feared it would be forgotten.²⁴  Witzel's summary agrees:  "the Vedas have been written down only during the early second millennium CE".  He adds that "almost all printed editions depend on the late manuscripts that are hardly older than 500 years, not on the still extant and superior oral tradition."¹³  The two oldest Veda manuscripts known are copies of the White Yajurveda from Nepal and western Tibet, of about AD 1150.⁵⁴

So the claim that Vyāsa "put the Vedas in writing" five thousand years ago, and the Prime Minister's Office's "Vedas written 5000 years ago", are not just unproved but contrary to the tradition's own practice.  The Brahmins refused to write the Veda, and the first writing of it known to an outside witness is about a thousand years old.

How good was the oral tradition?

This is where a Christian reader should be fair, because the evidence is strong.  Witzel, no friend of exaggerated Vedic claims, calls the result "an impeccable textual transmission superior to the classical texts of other cultures; it is, in fact, something like a tape-recording of ca. 1500—500 BCE. Not just the actual words, but even the long-lost musical (tonal) accent (as in old Greek or in Japanese) has been preserved up to the present."¹³  In 2001 he put it more plainly:  "the wording and even tone accents, long lost from popular speech, have been preserved perfectly, almost like a tape recording."¹⁵

But the tape had gaps.  Witzel himself notes that between the first complete collection and Śākalya's word-by-word text lay "a gap of several centuries during which the transmission of the collected RV text was affected by some unknown, rather erratic individuals who made some minor, not always consistent changes in the received text."⁵³  Only one recension of the Rigveda survives, that of the school of Śākalya;  others "have been lost or are only rumored about so far."¹³  UNESCO reports that "only thirteen of the over one thousand Vedic recitation branches have survived", the thousand being the tradition's own count, and Witzel notes that "some texts have been lost even during the past few decades."¹³⁵²  And before each school fixed its text, the same verses circulated in different forms.  Maurice Bloomfield's concordance of Vedic verse and formula has about 90,000 entries.  Nearly a third occur more than once, and about a third of those differ between their occurrences:  "roughly 10,000" variant mantras.  The variations "range all the way from change of a single letter in a single word, to radical rearrangements of the whole text".²⁶  His collaborator Franklin Edgerton concluded that "Faults of memory no doubt entered largely into these variations".²⁶

The fair verdict is that each school's text was preserved with extraordinary exactness once it was fixed, and that the fixing came after a period of oral variation that left about ten thousand variants behind.

The same standard applied to the Bible

The series this article belongs to applies one standard to every scripture.  If a long gap between composition and the oldest copy counts against one text, it counts against all.  On that measure the Rigveda stands behind the Bible.

The comparison cuts both ways.  The Bible's manuscripts are far closer to its composition.  But the Vedic tradition bridged its longer gap by a method that, for verbatim wording within a school, is at least as exact as any scribe's.  A skeptic who trusts the Rigveda's wording across 2,300 unwritten years cannot reasonably call a century between the Gospels and their first papyri fatal.  And a Christian who points to the Gospels' early papyri should grant that the Vedic reciters achieved a different kind of fidelity.  The details of the biblical evidence are in New Testament Manuscripts & Variants and Which Bible Text Gives the Right Date for Creation?.  The Historical Buddha and the Early Texts makes the same comparison for the Pāli canon.

Faithful transmission is one question and the truth of what is transmitted is another.  A perfectly preserved hymn tells us what its poet said, not that its gods exist.  That question is outside this article.

Part 7: The Vedas and the Bible's chronology

The biblical dates for the Flood depend on which text of Genesis is followed.  On the Masoretic Hebrew text the Flood falls about 2518 BC, or 2348 BC on Ussher's older reckoning;  on the Samaritan, about 3108 BC;  on the Greek Septuagint, about 3298 BC.  The arithmetic is set out in Which Bible Text Gives the Right Date for Creation?.  Young-earth dates for Babel run from about 2500 to 2000 BC on the Masoretic text, as When Was the Tower of Babel? explains.

Against those dates the claims tested here sort themselves out:

So the mainstream date, which this article accepts on the evidence, sits comfortably inside a young-earth history:  the Rigveda's poets were descendants of the dispersion, composing some centuries after it.  The early dates conflict with the Bible, but this article has not rejected them for that reason.  Talageri's chronology fails on the horse and chariot, on the genetic sequence and on the weakness of its anchors;  the astronomical dates fail because they date observations in later texts and depend on assumptions the texts do not state.  A reader who rejects the Bible altogether has the same reasons to reject them.

The family to which Vedic Sanskrit belongs is another matter.  Indo-European is older than the Rigveda, and the time needed for its branches to diverge is a real difficulty for a young-earth Babel.  That is tested in How Old Are the Language Families? and Is There Time Since Babel for the Language Families?, which find that Hittite and Vedic diverged too far for the fastest measured rates of change on a Masoretic Babel, while the Septuagint date with small founding groups nearly fits.

One more difficulty should be stated plainly.  This article has used conventional dates throughout:  the Indus cities at about 2600-1900 BC, the Rakhigarhi burial at about 2800-2300 BC by radiocarbon on charcoal, the Sintashta chariots at about 2000 BC, the geologists' thousands of years.  Several of these fall before the Masoretic Flood.  A young-earth reader must hold that radiocarbon and luminescence ages reaching back before the Flood are too old, as discussed in Radiocarbon Dating and Egypt and the Flood Date.  That is a problem for the Indus civilisation and for every early culture, and it is not solved here.  But it does not touch the Rigveda's date much, because that date rests on the Mitanni treaty of the fourteenth century BC, which is fixed by Near Eastern written chronology, and on the order of events:  the Indus cities first, then the steppe ancestry and the chariot, then the hymns, then iron.  Compressing the earlier radiocarbon dates would squeeze that sequence, not reverse it.

Objections and responses

"The Aryan migration is a colonial invention, made to tell Indians their civilisation came from outside."  The nineteenth-century story was told in racial and colonial terms, and Indian suspicion of it is understandable.  Bryant, who is sympathetic to that suspicion, writes that there are "some very good reasons for Indian scholars to be highly suspicious of the fact that the ancient history of their country was constructed by an imperial power", and adds:  "This does not justify replacing one perceived myth with another."³⁸  The evidence weighed here is not colonial.  The Mitanni texts came to light in Hugo Winckler's excavations at Boğazköy in 1907, the Sintashta chariots and the ancient genomes are recent finds, and the Rakhigarhi skeletons were excavated and sampled by Indian teams.³⁸¹⁸  Nor does that evidence show an "invasion".  Niraj Rai, a co-author of the Rakhigarhi study, put it carefully:  "There is a difference between migration and movement. There was certainly some mixing and assimilation, but we can't call that an invasion."⁶⁰

"The Rakhigarhi study's own lead author says it disproves the migration."  He said so in a press note, not in the paper.  The paper says the opposite about language, and its co-author Narasimhan disagreed in public, as Part 4 shows.  Even Talageri conceded the point.

"Genes are not languages."  True, and this article does not claim the DNA proves the date.  The DNA shows a movement of people from the steppe into South Asia between about 1900 and 1500 BC, concentrated in the lineages that kept the Vedas.  The mainstream account predicts that pattern;  the early-date account has to explain it away.

"No horse bones in the Indus cities is an argument from silence."  It is.  One securely dated horse skeleton in a mature Harappan layer, or a spoked chariot wheel before 2000 BC anywhere in India, would change the case.  But the two best-known claims of that kind, the "horse seal" and the Sanauli "chariots", turned out to be an altered photograph and a solid-wheeled vehicle with no horse.

"The astronomy is exact.  The Pleiades rose due east about 2950 BC, and the Vedic texts say so."  The arithmetic is right, as Part 2 shows.  But the statement is in a Brāhmaṇa that knows iron, so it records an inherited observation or a loose one, and its date moves by eight centuries with the observer's assumed horizon.  It says nothing about when the Rigveda's hymns were composed.

"The Sarasvati really was a great Himalayan river in early Harappan times."  On Chatterjee's 2019 study, it was fed by Himalayan sediment until about 4.5 ka, and that is a genuine point for the early-date side.  But the same study says the river "had already lost its glacial connection" by the time the cities matured, Singh's team puts the Sutlej's departure thousands of years earlier, and the only evidence of such a river reaching the sea is from before 10 ka.  The Sarasvati cannot fix the Rigveda's date in either direction.

"Max Müller admitted the date was a guess."  He did, of his 1859 method.  The date has since been supported by the Mitanni treaty, the horse and chariot, and the genetics, none of which he knew.

"Iron in the Ganges plain by 1800 BC means the Rigveda could be older."  An earlier iron date weakens the upper bound only.  It does not move the lower bounds set by the chariot, the absence of cities and the arrival of steppe ancestry.

"Christians accept the late date because it fits their chronology."  The date argued here is the one held by secular specialists, and every source for it is secular.  This article also states plainly, in Part 7, where the same conventional dates make trouble for a young-earth chronology.

"The Vedas were preserved more faithfully than the Bible, so the Bible deserves less trust."  For verbatim wording within a school, the Vedic recitation is at least as exact as any scribal tradition.  But it also left about 10,000 variant mantras between schools, and its oldest written copies are more than 2,300 years younger than the hymns.  The Gospels' oldest papyri are within about 150 years of their writing, as Part 6 sets out.  Each tradition should be judged by its own evidence and by the same standard.

Issues and unanswered questions

1. No ancient genome from the Vedic heartland. The Rakhigarhi woman is one undated individual from one Indus town. No ancient DNA has been published from Harappa, Mohenjo-daro, the Ganges plain or the Punjab of 1500-1000 BC. Such genomes could confirm or upset Part 4.
2. The horse figures were not checked at source. Witzel gives Meadow's date for the first horse bones in north India as "before c. 1700 BCE" in 2001 and "before c. 2000 BCE" in 2000. Meadow and Patel's 1997 paper could not be obtained for this article.
3. The geologists disagree. Singh's team in 2017 and Chatterjee's in 2019 give incompatible histories for the Sutlej's flow in the Ghaggar channel. This article does not resolve them.
4. The Pleiades statement is a real residue. A strict reading of the Śatapatha Brāhmaṇa's "never swerve from the east" fits about 3000 BC. The mainstream answer, that it is inherited or loosely meant, is reasonable but is an interpretation, not a measurement.
5. The Indus script is undeciphered. Bryant called its decipherment the only thing that could "convincingly settle this entire debate". If it proved Indo-Aryan, much of this article would need revision.³⁸
6. Talageri's internal chronology was not tested in detail. His ordering of the books by composers and kings is a large argument, and this article has answered only its anchors. A full reply would weigh Witzel's "five generations" against Talageri's two millennia hymn by hymn.
7. The oldest Rigveda manuscript specifically was not dated from a primary source. The oldest known Veda manuscripts, of about AD 1150, are of the Yajurveda.
8. Jamison and Brereton's 2014 translation, the standard modern Rigveda, could not be read for this article, so its introduction's dating and its account of the text's transmission are not used.
9. The young-earth problem with Indus dates is real. The Indus civilisation's conventional radiocarbon dates begin before the Masoretic Flood. This article relies on those dates for the order of events and leaves the absolute calibration to Radiocarbon Dating.

Verdict

The Rigveda was composed in the second millennium BC, most likely between about 1500 and 1200 BC, and was carried by memory until it was first written down about a thousand years ago.  The date rests on independent lines that agree:  the Mitanni treaty's Vedic gods in the fourteenth century BC, the horse and spoked chariot that appear on the steppe about 2000 BC, the absence of cities and of iron, and ancient DNA that shows steppe ancestry entering South Asia about 1900-1500 BC and concentrating in the Brahmin lineages that kept the hymns.

The early dates are argued in good faith, and some of their pieces are real:  the Pleiades arithmetic, a Sarasvati with Himalayan water into early Harappan times, iron in the Ganges plain before 1200 BC, and the honest truth that genes do not prove language.  But none of these dates a hymn, and each early chronology runs into the horse, the chariot and the genetic sequence.  The claims that the Vedas were written five thousand years ago are contradicted by the Brahmins' own refusal to write them.

The Vedic oral tradition deserves its reputation.  Within each school it preserved wording and even pitch accents with an exactness that scribes did not match.  It also shows, in its ten thousand variant mantras and its lost schools, the marks of a long and imperfect oral prehistory.  By the same standard applied to the Bible, the Rigveda is an old text faithfully kept, from a much later and much thinner written record.
