Sripathy

During Ninth Century, a then Indian kingdom called Mahodayapuram, which is currently in the state of Kerala currently called Kodungalloor there lived a king called Ravi Varma Devan. He built a star bungalow in which he invited great mathematicians of the time to stay. This made, Mahodayapuram to a mathematical research area until the eleventh century.

Currently only one of the names of mathematicians called Sripathy, who lived there is known to historians. His works available now, Dhikotidakarana (written in 1039), a work of twenty verses on solar and lunar eclipses; Dhruvamanasa (written in 1056), a work of 105 verses on calculating planetary longitudes, eclipses and planetary transits; Siddhantasekhara a major work on astronomy in 19 chapters; and Ganitatilaka, an incomplete arithmetical treatise in 125 verses based on a work by Shridhara. These are the sources available for knowing the period. There is mention of the name Govindaswamy, a mathematician of the time in some literature of the time. Many of the mathematicians now known of the period uses this name with a lot of respect. But none of his literature are now available.

There are no much literature or any other proof available for the period between eleventh century and thirteenth century. The known of the time is a drop and the unknown an ocean. It is believed in my place that abundance of knowledge of the period was lost in the cycle of time.
