Brahmagupta

Brahmagupta, whose father was Jisnugupta, wrote important works on mathematics and astronomy. In particular he wrote BrahmasphutasiddhantaⓉ, in 628. The work was written in 25 chapters and Brahmagupta tells us in the text that he wrote it at Bhillamala which today is the city of Bhinmal. This was the capital of the lands ruled by the Gurjara dynasty.

Brahmagupta became the head of the astronomical observatory at Ujjain which was the foremost mathematical centre of ancient India at this time. Outstanding mathematicians such as Varahamihira had worked there and built up a strong school of mathematical astronomy.

In addition to the BrahmasphutasiddhantaⓉ Brahmagupta wrote a second work on mathematics and astronomy which is the KhandakhadyakaⓉ written in 665 when he was 67 years old. We look below at some of the remarkable ideas which Brahmagupta's two treatises contain. First let us give an overview of their contents.

The BrahmasphutasiddhantaⓉ contains twenty-five chapters but the first ten of these chapters seem to form what many historians believe wa
