Many scientific works, like "Ganitasarasangrahamu" by Pavuluri Mallana and "Prakirnaganitamu" by Eluganti Peddana, were written in the 12th century. "Sumati Shatakam", which is a "neeti" ("moral"), is one of the most famous Telugu Shatakams. Shatakam is composed of more than a 100 "padyalu" (poems). According to many literary critics "Sumati Shatakam" was composed by Baddena Bhupaludu () (CE 1220–1280). He was also known as Bhadra Bhupala. He was a Chola prince and a vassal under the Kakatiya empress Rani Rudrama Devi, and a pupil of Tikkana. If we assume that the "Sumati Shatakam" was indeed written by Baddena, it would rank as one of the earliest Shatakams in Telugu along with the "Vrushadhipa Satakam" of Palkuriki Somanatha and the "Sarveswara Satakam" of Yathavakkula Annamayya. The "Sumatee Shatakam" is also one of the earliest Telugu works to be translated into a European language, as C. P. Brown rendered it in English in the 1840s. Srinatha () (1365–1441) popularised the "Prabandha" style of composition. He was a minister in the court of Pedakomati Vemareddy of Kondaveedu and wrote "Salivahana Saptasati", "Shivaratri Mahatyam", "Harivilasa", "Bhimakanda", "Kashi khandam", "Shringara Naishadham", "Palanati Veera charitra", "Dhananjaya Vijayam", "Sringara Dipika". These works were concerned with history and mythology. Srinatha's "Srungara Naishadhamu" is a well-known example of the form. Srinatha was widely regarded as the "Kavi Sarvabhowma" ("the emperor among poets"). Kumaragiri Vema Reddy (), popularly known as Yogi Vemana, was a 14th-century Telugu poet. His poems were written in the popular vernacular of Telugu, and are known for their use of simple language and native idioms.
