Most of the inscriptions in the Bhuvarahasvami temple belong to the period of the Vijayanagara kings starting from the 15th century A.D. Some of the inscriptions are also the feudatories of the Vijayanagara kings. The inscriptions also narrate that some of the sub shrines of the temple constructed by the Nayaka kings. An inscription of the Vijayanagara king, Virupaksha II dated 1471 A.D is found on the walls of the temple. This inscription states the story of the gift of a village to this temple called in this epigraph as Aadivaraha Naayanar Koil. Inscriptions of other rulers like Sriranga I (1572-1585 A.D.) and Venkata II (1586-1614 A.D.), some of which are in Telugu are also found here, which depict the legendary stories associated with this Bhuvarasvami temple.
Apart from the major inscriptions described above, there are some other inscriptions, which narrate the stories of other kings associated with the Bhuvarasvami Temple. The Nayaka ruler of Tanjavur, Achyutappa Nayaka (1560-1614 A.D.) rendered great service to this temple. He was responsible for the construction of the Purushasukta mandapa and also many of the smaller shrines. He was entrusted with the task of temple administration and control of its treasury and also donated many villages for the maintenance of this temple.
The inscriptions are significant enough to denote the date of the construction of the temple and the accounts of those kings who offered their valuable contribution to the temple.
