Person: Varahamihira
Varahamihira was an Indian astrologer whose main work was a treatise on mathematical astronomy which summarised earlier astronomical treatises. He discovered a version of Pascal's triangle and worked on magic squares.
Mathematical Profile (Excerpt):
 The school of mathematics at Ujjain was increased in importance due to Varahamihira working there and it continued for a long period to be one of the two leading mathematical centres in India, in particular having Brahmagupta as its next major figure.
 The most famous work by Varahamihira is the Pancasiddhantika (The Five Astronomical Canons) dated 575 AD.
 One treatise which Varahamihira summarises was the RomakaSiddhanta which itself was based on the epicycle theory of the motions of the Sun and the Moon given by the Greeks in the 1st century AD.
 Other works which Varahamihira summarises are also based on the Greek epicycle theory of the motions of the heavenly bodies.
 There is, however, quite a debate about interpreting data from Varahamihira's astronomical texts and from other similar works.
 Varahamihira made some important mathematical discoveries.
 In particular he examines a pandiagonal magic square of order four which occurs in Varahamihira's work.
Born 505, Kapitthaka, India. Died 587, India.
