The Vishńu Puráńa has kept very clear of particulars from which an approximation to its date may be conjectured. No place is described of which the sacredness has any known limit, nor any work cited of probable
recent composition. The Vedas, the Puráńas, other works forming the body of Sanscrit literature, are named; and so is the Mahábhárata, to which therefore it is subsequent. Both Bauddhas and Jains are adverted to. It was therefore written before the former had disappeared; but they existed in some parts of India as late as the twelfth century at least; and it is probable that the Puráńa was compiled before that period. The Gupta kings reigned in the seventh century; the historical record of the Puráńa which mentions them was therefore later: and there seems little doubt that the same alludes to the first incursions of the Mohammedans, which took place in the eighth century; which brings it still lower. In describing the latter dynasties, some, if not all, of which were no doubt contemporary, they are described as reigning altogether one thousand seven hundred and ninety-six years. Why this duration should have been chosen does not appear, unless, in conjunction with the number of years which are said to have elapsed between the great war and the last of the Andhra dynasty, which preceded these different races, and which amounted to two thousand three hundred and fifty, the compiler was influenced by the actual date at which he wrote. The aggregate of the two periods would be the Kálí year 4146, equivalent to A. D. 1045. There are some variety and indistinctness in the enumeration of the periods which compose this total, but the date which results from it is not unlikely to be an approximation to that of the Vishńu Puráńa.
It is the boast of inductive philosophy, that it draws its conclusions from the careful observation and accumulation of facts; and it is equally the business of all philosophical research to determine its facts before it ventures upon speculation. This procedure has not been observed in the investigation of the mythology and traditions of the Hindus. Impatience to generalize has availed itself greedily of whatever promised to afford materials for generalization; and the most erroneous views have been confidently advocated, because the guides to which their authors trusted were ignorant or insufficient. The information gleaned by Sir Wm. Jones was gathered in an early season of Sanscrit study, before the field was cultivated. The same may be said of the writings of
lxxiii:96 Systema Brahmanicum, &c.
lxxiii:97 Asiatic Researches.
lxxiii:98 Account of the Hindus.
lxxiii:99 Mythologie des Hindous, edited by Canoness Polier.
