The ancient Babylonians were probably the first to use Astrology. After that this science moved to countries like China and India. Greek astronomer Ptolemy was the first ever person to write a book on Astrology. He codified the sun sign astrology that we know today. Ptolemy tried to predict the positions of celestial bodies relative to each other and the earth through knowledge of their orbital motions. During his time, astrology was a part of astronomy. Later, astronomy became an exact science and Astrology remained a part of Theology. Planetary observation is the basis of Astrology.

History of Astrology is an important part of civilization and goes back to the early days of the human race. Apart from being centers of learning in medicine, Baghdad and Damascus were also known as centers of astrology and astronomy. Arabs were pioneers in astronomy before the advent of Islam. The Babylonians were the first to name the days of the week after the Sun, Moon, and planets. They were also the first to set out the twelve houses of the horoscope. Egypt was one of the most important places in the development of astrology. It is thought that some of the astrological signs of the zodiac originated in Egypt. Astrology was practiced even in the Vedic times in India. Astrology is one of the six disciplines of vedanga. The Hindus believe that human fortune or misfortune in life is due to karma, and karma is believed to be influenced by the movements of the planets. Among the Hindus, Brahmins are considered to be the best authorities on astrology. In Modern India too, astrology is extensively used to determine the future and improve life. Astrology is studied and practiced by many in India. It is regarded as vital in Indian culture. It is used to make decisions about marriage, starting of new business, and moving into a new house etc. Ancient Hindu Scriptures too gives a lot of importance to the various aspects of planetary motions and its effects on humans. Chinese astrology stresses on the five elements, metal, wood, water, fire, and earth. Even the zodiac signs used by them are also different from other forms of astrology. China was isolated from the western for a long time. That is why Chinese astrology was unknown to the western world. As Chinese astrology developed independently, a lot of difference can be seen between the western concepts of astrology and the Chinese version. But the Chinese and Indian astrologers were in touch every now and then. Therefore, these two schools have a few things in common. In spite of the geographical isolation, there are a few surprising similarities between the western and the Chinese thoughts on astrology.
