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.
[2] The title Veṇvāroha literally means 'Bamboo Climbing' (Veṇu 'bamboo' + āroha 'climbing') and it is indicative of the computational procedure expounded in the text.
Acyuta Piṣārati (1550–1621), another prominent mathematician/astronomer of the Kerala school, has composed a Malayalam commentary on Veṇvāroha.
[4] Veṇvāroha has been studied from a modern perspective and the process is explained using the properties of periodic functions.
