India has a rich history, with many artists and mathematicians being parts of the Kings’ courts across the sub-continent. One such distinguished man was Varahamihira, an astronomer from Ujjain. Varahamihira was born in Malwa (now Madhya Pradesh) in 505 AD and was educated at Kapitthaka. He then went on to write several texts that have now become an important part of Indian history.

Varahamihira is believed to be a part of the nine jewels or “Navaratnas” of King Yashodharman Vikramaditya of Malwa’s court. Navratanas were usually extraordinary individuals of specific calibres found across courts of many kings. These gifted people would not only entertain the king, but the emperor would often rely on these nine people for advice whenever it was required.
2. Clever all around.
Varahamihira was not just astronomer extraordinaire, he also seemed to be dexterous with languages. After learning the Greek language he praised the Greeks for being “Well trained in sciences.”
It is believed that it was Aryabhata who inspired Varahamihira to pursue mathematics and astronomy. A young Varahamihira apparently met Aryabhata at Kusumapura (present-day Patna) and was supremely impressed by the famous mathematician.
4. The Persian connection.
Verses of Varahamihira’s work have been quoted by famous Persian scholar Al Biruni, who is recognised as the Father of Comparative Religion.
5. Varahamihira’s most important text.
Varahamihira’s Pancha-Siddhantika (575 CE) is an important text as it is based on older works that are now all lost. It is a discussion on mathematical astronomy that compiles earlier works by five other authors. These works are Surya Siddhanta, Vashishtha Siddhanta, Romaka Siddhanta, Paitamaha Sidhanta and Paulisa Siddhanta.
