Brief and to the point, the story of Manu and the Flood served its purpose of introducing a new progenitor of the human race and, incidentally, explaining the name of a mountain. Such, however, was too modest an interpretation for later generations. Myth, the smoke of history, is seen to signal new and more relevant meanings when espied from the distance of later millennia. In time the predicament of the small fish liable to be devoured by larger fish became a Sanskrit metaphor for an anarchic state of affairs (matsya-nyaya) equivalent to ‘the law of the jungle’ in English. Manu’s flood, like Noah’s, came to be seen as the means of putting a stop to this chaos. And who better to orchestrate matters and so save mankind than Lord Vishnu? A minor deity when the Vedas were composed, Vishnu had since soared to prominence as the great preserver of the world in the Hindu pantheon and the second member of its trinity. Thus, in due course, the Flood became a symbol of order-out-of-chaos through divine intervention, and the fish (matsya) came to be recognised as the first of the nine incarnations (avatara) of Lord Vishnu. Myth, howsoever remote, serves the needs of the moment. So does history, in India as elsewhere.
Some historians have dated the Flood very precisely to 3102 BC, this being the year when, by elaborate computation, they conclude that our current era, the Kali Yug in Indian cosmology, began and when Manu became the progenitor of a new people as well as their first great king and law-giver. It is also the first credible date in India’s history and, being one of such improbable exactitude, it deserves respect.
Other historians, while conceding the importance of 3102 BC, have declared it to be not the date of the Flood but of the great Bharata war. A Trojan-style conflict fought in the vicinity of Delhi, the war involved both gods and men and was immortalised in the Sanskrit verse epic known as the Mahabharata, the composition of whose roughly 100,000 stanzas constituted something of an epic in itself. This war, not the flood, was the event that marked the beginning of our present era and must, it is argued, therefore belong to the year 3102 BC. Complex astronomical calculations are deployed in support of this dating, and an inscription carved on a stone temple at Aihole in the south Indian state of Karnataka is said to confirm it.
But the Aihole memorialist, endowing his temple 1600 kilometres from Delhi and nearly four thousand years later, may have got it wrong. According to the genealogical listings in the Puranas, a later collection of ‘ancient legends’, ninety-five generations passed away between the Flood and the war; other evidence based on sterner, more recent, scholarship agrees that the war was much later than the fourth millennium BC. This greatest single event in India’s ancient history, and the inspiration for the world’s longest poem, did not occur until ‘C1400 BC’ according to the History and Culture of the Indian People, a standard work of many volumes commissioned in the 1950s to celebrate India’s liberation from foreign rule and foreign scholarship.
Nevertheless, 3102 BC sticks in the historical gullet. Such are the dismal uncertainties of early Indian chronology that no slip of the chisel is going to deny the historian the luxury of a real date. Corroboration of the idea that it may, after all, apply to a Flood has since come from the excavations in distant Iraq of one of Mesopotamia’s ancient civilisations. There too archaeologists have found evidence of an appalling inundation. It submerged the Sumerian city of Shuruppak, and has been dated with some confidence to the late fourth millennium BC. In fact, 3102 BC would suit it very well.
This Sumerian inundation, and the local Genesis story in the Epic of Gilgamesh which probably derived from it, is taken to be the origin of the legend of the Flood which eventually found its way into Jewish and Christian tradition. Yet in many respects the Sumerian account is more closely echoed in the Indian version than in the Semitic. For instance, just as in later Hindu tradition Manu’s fish becomes an incarnation of the great god Vishnu, so the Sumerian deity responsible for saving mankind is often represented in the form of a fish. ‘It is the agreement in details which is so striking,’ according to Romila Thapar.2 The details argue strongly for some common source for this most popular of Genesis myths, and scholars like Thapar, ever ready to expose cultural plagiarism, see both Manu and Noah as relocated manifestations of a Sumerian prototype.
The tendency to synchronise and subordinate things Indian to parallel events and achievements in the history of countries to the west of India is a recurrent theme in Indian historiography and has rightly incurred the wrath of some Indian historians. So much so that they sometimes go to the other extreme of denying that any creative impetus, any technological invention, even any stylistic convention, ever reached India from the west – or, indeed, the West. And in the case of the Flood they may have a point. Subject to the annual deluge of the monsoon and living for the most part on the flat alluvial plains created by notoriously errant river systems, the people of north India have always had far more experience of floods, and far more reason to fear them, than their neighbours in the typically more arid lands of western Asia.
Floods, though now associated more with the eastern seaboard of the Indian subcontinent and Bangladesh, still annually inundate vast areas of the Ganga and Indus basins. They have always done so. One such Gangetic flood, dated by archaeologists to about 800 BC, destroyed the town of Hastinapura which, after the great Bharata war, had become the capital of the descendants of Arjuna, one of the war’s main protagonists. Since the flooding of Hastinapura is also recorded in Sanskrit textual tradition, and since the same tradition says that the town was then under its seventh ruler since the war, an approximate date for the war itself of about 975 BC has been postulated.
Thus, for the titanic struggle recorded in the Mahabharata, we already have three dates: 3102 BC, C1400 BC and C950 BC. A couple of millennia one way or the other is a long time even in prehistoric terms. India’s history, though undoubtedly ancient, leaves much room for manoeuvre. A mistranslated word from one of the many voluminous, difficult and defective texts wherein, long after their composition, the Vedic verses were eventually written down, can create havoc. Similarly a chance discovery of no obvious provenance can prompt major revisions.
Another flood, later than the Sumerian one but much earlier than that at Hastinapura and so perhaps a serious contender for the one which Manu survived, is thought by some to have once inundated the plains of the lower Indus in what is now Pakistan. Geologists date it to some time soon after 2000 BC, and believe that it may in fact have been a succession of inundations. Whether they were the result of climate change, of tectonic action lower down the river resulting in damming and the formation of inland lakes, or simply the cumulative effect of annual siltation is not clear. But whatever the cause, the floods were bad news for those agriculturalists who had pioneered a highly productive economy based on growing cereals in the fine soil alongside the river. Managing the river’s seasonal rise so as to enrich and irrigate their fields was the key to their success. An annual surplus had generated wealth, encouraged craft industries and fostered trade. Settlements had become cities. Along the lower Indus and its tributaries had grown up one of the world’s first urban societies, a contemporary of those on the Nile and the Euphrates and a rival for the tag of ‘the cradle of civilisation’.
Then, soon after 2000 BC according to the archaeologists, came the floods. If they did not actually overwhelm this precocious civilisation, they certainly obliterated it. In time, layer after layer of Indus mud, possibly wind-blown as well as water-borne, choked the streets, rotted the timbers, and piled high above the rooftops. The ground level rose by ten metres and the water table followed it. Meanwhile the river resumed its regular flow and found new channels down which to flood. On top of the cities, now consigned to oblivion beneath tons of alluvium, other peoples grazed their goats, sowed their seeds and spun their myths. A great civilisation was lost to memory.
Not until nearly four thousand years later, in fact in the early 1920s, was its existence even suspected. It was pure chance that Indian and British archaeologists, while investigating later more visible ruins at Mohenjo-daro in Sind and at Harappa in the Panjab, made
