Pingali Surana (16th century C E) was a Telugu poet and was one of the Astadiggajas. Surana wrote Garuda Puranam, Prabhavatee Pradyumnamu, Raghava Pandaveeyam and Kalapurnodayamu in 1500 C E. He dedicated Garuda Puranam to his father and Kalapurnodayam to the Nandyal King. Kalapurnodayam is more of a novel than poetry and Raghava Pandaveeyam is in dvayarthi (double meaning) style. Kalapurnodayamu means full bloom of art. Surana used advanced literary techniques in Indian literature such as flashbacks and character transformation.
