The Gupta period witnessed a brilliant activity in the sphere of mathematics, astronomy, astrology and medicine. Aryabhatta wasa great mathematician and astronomer. He wrote the book Aryabhatiya in 499 A.D.
It deals with mathematics and astronomy. It explains scientifically the occurrence of solar and lunar eclipses. Aryabhatta was the first to declare that the earth was spherical in shape and that it rotates on its own axis. However, these viewswere rejected by later astronomers like Varahamihira and Brahmagupta. Varahamihira composed Pancha Siddhantika, the fiveastronomical systems.
He was also a great authority on astrology. His work Brihadsamhita is a great work in Sanskrit literature. It deals with a variety of subjects like astronomy, astrology, geography, architecture, weather, animals, marriage and omens. His Brihadjataka is considered to be a standard work on astrology. In the field of medicine, Vagbhata lived during this period.
He was the last of the great medical trio of ancient India. The other two scholars Charaka and Susruta lived before the Gupta age. Vagbhata was the author Ashtangasamgraha (Summary of the eight branches of medicine).
