History depicts three main branches of astrology in its record: Western astrology, Indian astrology, and Chinese or East Asian astrology.
Astrology in Babylon and Greece
Ancient Babylonians are founders of the study of Western astrology and all the belief associated with it, which came as a part of astronomy. Directly or indirectly through the Babylonians, this astrology got spread all over the world. It started spreading in Greece about the middle of the 4th century BC and it had arrived Rome before the advent of the Christian era.
Astrology in Rome, Egypt and Hellenistic period
History says that during the Hellenistic and Roman periods, both astronomy and astrology were practiced in the Nile region while Greek culture introduced into Egypt.
Astrology in Arab
Astrology took another shape while Arabs included its own definition into it during 7th to the 13th century.
Astrology in Europe and America
During 14th and 15th centuries, Astrologers from Europe started influencing the whole world. At that time, The Mayans of Central America and the Aztecs also took place in the list of astrology.
Astrology in India
India developed knowledge in astrology about 6,500 BCE and it is found that original manuscripts were written about 3,700 BCE.
It is said that few original manuscripts have been destroyed or lost and then actual copies of these original manuscripts were again written by alter astrologers. These are kept in the libraries of Maharajas and in the libraries of certain states of India.
One of the prominent ancient authors of Vedic astrology is Pita Maha. He wrote a treatise on astrology, which is famously known as Pita Maha Siddhant(a) about 3,000 BCE. Another name in astrology is Vashishtth(a) who wrote several books on astrology, astronomy and philosophy. His most famous work is Vashishtth(a) Siddhant(a). He wrote many 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.
Astrology in China
Apart from Vedic records of India, if any country has written its name in the history of ancient astrology, then it is supposed to be the name of China. This country is highly painstaking in keeping record of all the manuscripts, original or re-written, just like India.
