Venvaroha
Veṇvāroha is a work in Sanskrit composed by Mādhava of Sangamagrāma (c. 1350 – c. 1425), the founder of the Kerala school of astronomy and mathematics. It is a work in 74 verses describing methods for the computation of the true positions of the Moon at intervals of about half an hour for various days in an anomalistic cycle. This work is an elaboration of an earlier and shorter work of Mādhava himself titled Sphutacandrāpti.[1] Veṇvāroha is the most popular astronomical work of Mādhava.[2]
