Lesson plan
Devācārya
Devācārya was an Indian astronomer hailing from Kerala, India who flourished during the second half of 7th century CE. He is the author of a karaņa text on astronomy titled Karaņaratna which deals with almost every aspect of planetary astronomy generally discussed in other Indian texts on astronomy. This work is important in the study of history of astronomy in India as it sheds valuable light on the methods used by the astronomers of South India, in the seventh century CE, in their astronomical computations. No personal information about Devācārya is known except that his father's name was Gojanma and that Devācārya was a great devotee of Viṣṇu, Ŝiva and Brahma. That he flourished during the second half of the seventh century CE is inferred from the fact the epoch (the date from which the planetary computations are to be commenced) specified in Karaņaratna is the first day of the year 611 Saka Era which corresponds to 26 February 689 CE.
