Discovered from across Srisailam, Palnadu, Chāḍa, and Kōdada, the inscriptions date from the 2nd century CE to the late Vijayanagara period (1336 to 1646 CE). Written in languages such as Prākṛit, Sanskrit, and regional scripts like Brāhmī, Nāgari, and Telugu, they reflect the evolving literary and political landscape of South India.
