BHARAT (India)
In Bharat records exist today which point clearly to a highly developed knowledge of astrology as far back as about 6,500 BCE and actual manuscripts are still extant which were written about 3,700 BCE.
Some of the originals have been destroyed or lost but actual copies of these originals were made by alter astrologers. These are to be found in the libraries of Maharajas and in the libraries of certain states in Bharat.
Actual, detailed records of astrological science are continuous from about 6,500 BCE.
One of the earliest authors of Vedic astrology, copies of whose work are still to be found, is Pita
Maha who wrote a treatise on astrology called Pita Maha Siddhant(a). He lived and wrote this book about 3,000 BCE.
Five hundred years later, another author-astrologer named Vashishtth(a) wrote several books on astrology, astronomy and philosophy. His most important work, and one which was used as an authority by all subsequent writers on the subject, is Vashishtth(a) Siddhant(a), but he wrote may other equally erudite and authoritative texts such as the Panch Siddhant(a) Kosh(a), Soory(a)
Siddhant(a), Nityanand(a), Brhat Jatak(a), Aryabhat, Mansagari, Ranveer, and the Laghu Parashar.
E. M. Plunkett writes in his book Ancient Calendars and Constellations:
"The opinion of the Greek writers at the beginning of the Christian era may be quoted as showing the high estimation in which Indian astronomy was held.
In the Life of Appollonius of Tyana, the Greek philosopher and astrologer, written by Philostratus about 210 CE, the wisdom and learning of Appollonius are set high above his contemporaries because he had studied astronomy and astrology with the sages of India."
In a book called You and Your Hand by the late Count Louis Hamon, known better as Cheiro, this statement is found:
"People who in their ignorance disdain the wisdom of ancient races forget that the great past of
India contained secrets of life and philosophy that following civilizations could not controvert, but
were forced to accept.
For instance, it has been demonstrated that the ancient Hindus understood the precession of the equinoxes and made the calculation that it [a complete cycle] took place once in every 25,870 years.
The observation and mathematical precision necessary to establish such a theory has been the
wonder and admiration of modern astronomers. They, with their modern knowledge and up-to-date instruments, are still quarrelling among themselves as to whether the precession, the most important feature in astronomy, takes place every 25,870 years or every 24,500 years.
The majority believe that the Hindus made no mistakes, but how they arrived at such a calculation is as great a mystery as the origin of life itself."
