In one of the earliest Nivids, Rishi Kutsa, a Hindu sage of the remotest antiquity, explains the allegory of the first laws given to the celestial bodies. For doing "what she ought not to do," Anâhit (Anaïtis or Nana, the Persian Venus), representing the earth in the legend, is sentenced to turn round the sun. The Sattras, or sacrificial sessions * prove undoubtedly that so early as in the eighteenth or twentieth century B.C., the Hindus had made considerable progress in astronomical science. The Sattras lasted one year, and were "nothing but an imitation of the sun's yearly course. They were divided, says Haug, into two distinct parts, each consisting of six months of thirty days each; in the midst of both was the Vishuvan (equator or central day), cutting the whole Sattras into two halves, etc."† This scholar, although he ascribes the composition of the bulk of the Brahmanas to the period 1400-1200 B.C., is of opinion that the oldest of the hymns may be placed at the very commencement of Vedic literature, between the years 2400-2000, B.C. He finds no reason for considering the Vedas less ancient than the sacred books of the Chinese. As the Shu-King or Book of History, and the sacrificial songs of the Shi-King, or Book of Odes, have been proved to have an antiquity as early as 2200, B.C., our philologists may yet be compelled before long to acknowledge, that in astronomical knowledge, the antediluvian Hindus were their masters.
At all events, there are facts which prove that certain astronomical calculations were as correct with the Chaldeans in the days of Julius Cæsar as they are now. When the calendar was reformed by the Conqueror, the civil year was found to correspond so little with the seasons, that summer had merged into the autumn months, and the autumn months into full winter. It was Sosigenes, the Chaldean astronomer, who restored order into the confusion, by putting back the 25th of March ninety days, thus making it correspond with the vernal equinox; and it was Sosigenes, again, who fixed the lengths of the months as they now remain.
In America, it was found by the Montezuman army, that the calendar of the Aztecs gave an equal number of days and weeks to each month. The extreme accuracy of their astronomical calculations was so great, that no error has been discovered in their reckoning by subsequent verifications; while the Europeans, who landed in Mexico in 1519, were, by the Julian calendar, nearly eleven days in advance of the exact time.
It is to the priceless and accurate translations of the Vedic Books, and to the personal researches of Dr. Haug, that we are indebted for the
