Veṇvāroha is a work in Sanskrit composed by Mādhava (c.1350 – c.1425) of Sangamagrāma 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.Veṇvāroha is the most popular astronomical work of Mādhava. It is dated 1403 CE. Acyuta Piṣārati (1550–1621), another prominent mathematician/astronomer of the Kerala school, has composed a Malayalam commentary on Veṇvāroha. This astronomical treatise is of a type generally described as Karaṇa texts in India. Such works are characterized by the fact that they are compilations of computational methods of practical astronomy. The title Veṇvāroha literally means Bamboo Climbing and it is indicative of the computational procedure expounded in the text. The computational scheme is like climbing a bamboo tree, going up and up step by step at measured equal heights.
