Around the same time, the Chalukya kings of Telangana also began using Telugu for inscriptions. Telugu was more influenced by Sanskrit than Prakrit during this period, which corresponded to the advent of Telugu literature. One of the oldest Telugu stone inscriptions containing literature was the 11-line inscription dated between 946 and 968 found on a hillock known as Bommalagutta in Kurikyala village of Karimnagar district, Telangana. The sing-song Telugu rhyme was the work of Jinavallabha, the younger brother of Pampa who was the court poet of Vemulavada Chalukya king Arikesari III. This literature was initially found in inscriptions and poetry in the courts of the rulers, and later in written works such as Nannayya's "Mahabharatam" (1022 ). During the time of Nannayya, the literary language diverged from the popular language. This was also a period of phonetic changes in the spoken language.
