"From their philosophical truth and universal reception I am strongly inclined to refer them to the authors of the Neros, or to that enlightened race, supposed by Bailly to have formerly existed, and to have been saved from a great catastrophe on the Himalaya Mountains. This is confirmed by an observation which the reader will make in the sequel, that these doctrines have been, like all the other doctrines of antiquity, gradually corrupted—incarnated, if I may be permitted to compose a word for the occasion."

Of this cycle, Bailly says: "No person could have invented the Neros who had not arrived at much greater perfection in astronomy than we know was the state of the most ancient Assyrians, Egyptians, and Greeks."

Toward the close of the eighteenth century the celebrated astronomer, Bailly, published a work entitled The History of Ancient Astronomy, in which he endeavored to prove that a nation possessed of profound wisdom and great genius, and of an antiquity far superior to the Hindoos or Egyptians, "inhabited the country to the north of India, or about fifty degrees north latitude." This writer has shown that "the most celebrated astronomical observations and inventions, from their peculiar character, could have taken place only in these latitudes, and that arts and improvements gradually travelled thence to the equator."

A colony of Brahmins settled near the Imans, and in Northern Thibet, where in ancient times they established celebrated colleges, particularly at Nagraent and Cashmere. In these institutions the treasures of Sanskrit literature were supposed to be deposited. The Rev. Mr. Maurice was informed that an immemorial tradition prevailed at Benares that all the learning of India came from a country situated in forty degrees of northern latitude. Other writers are of the opinion that civilization proceeded from Arabia; that the old Cushite race carried commerce, letters, and laws to all the nations of the East. Which of these theories is true, if either, may not with certainty be proved at present; yet that in the far distant past a race of people existed whose achievements exceeded those of any of the historic nations may not be doubted.

That the length of the year was calculated with greater exactness by an ancient and forgotten people than it was by early historic nations is proved by the cycle of the Neros. This cycle, which was formed of 7,421 lunar revolutions of 29 days, 12 hours, 44 minutes, and 3 seconds, or 219,146 days and a half, was equal to 600 solar years of 365 days, 5 hours, 51 minutes, and 36 seconds, which time varies less than three minutes from the present observations of the year's length. The length of the year as calculated by the Egyptians and other early historic nations was 360 days, which fact would seem to indicate that a science of astronomy had been developed in an earlier age which by the most ancient peoples of whom we have any historic records has been lost or forgotten. It has been said that if this cycle of the Neros "were correct to the second, if on the first of January at noon a new moon took place, it would take place again in exactly 600 years at the same moment of the day, and under all the same circumstances."(61)

The Varaha Calpa has the famous cycle of 4,320,000,000 years for its duration. This system makes the Cali Yug begin 3098 years B.C. A dodecan consisted of 5 days, and 72 dodecans formed a natural year of 360 days. According to the earlier calculations, 360 solar diurnal revolutions constituted a natural year. The doctrine of the ancients concerning these cycles is thus set forth by Godfrey Higgins:

"The sun, or rather that higher principle of which the sun was the emblem or the shekinah, was considered to be incarnated every six hundred years. Whilst the sun was in Taurus, the different incarnations, under whatever names they might go, were all considered but as incarnations of Buddha or Taurus. When he got into Aries, they were in like manner considered but as incarnations of Cristna or Aries, and even Buddha and Cristna were originally considered the same, and had a thousand names in common, constantly repeated in their litanies—a striking proof of identity of origin. Of these Zodiacal divisions the Hindoos formed another period, which consisted of ten ages or Calpas or Yugs, which they considered the duration of the world, at the end of which a general renovation of all things would take place. They also reckoned ten Neroses to form a period, each of them keeping a certain relative location to the other, and together to form a cycle. To effect this they doubled the precessional period for one sign—viz: 2160 years—thus making 4320, which was a tenth of 43,200, a year of the sun, analogous to the 360 natural days, and produced in the same manner, by multiplying the day of 600 by the dodecans 72 = 43,200. They then formed another great year of 432,000 by again multiplying it by 10, which they called a Cali Yug, which was measurable both by the number 2160, the years the equinox preceded in a sign, and by the number 600. They then had the following scheme:

A Cali Yug, or 600 (or a Neros) 432,000
A Dwapar, or Duo-par Age....864,000
A Treta, or tree-par Age... 1,296,000
A Satya, or Satis Age....1,728,000
————-
4,320,000

altogether 10 Ages, making a Maha Yug or Great Age. These were all equimultiples of the Cycle of the Neros 600, and of 2160, the twelfth part of the equinoctial precessional Cycle, and in all formed ten ages of 432,000 years each."(62)
