Yerrapragada: (Telugu: ఎర్రాప్రగడ) who lived in the 14th century, finished the epic by completing the third chapter. He mimics Nannaya's style in the beginning, slowly changes tempo and finishes the chapter in the writing style of Tikkana. These three writers – Nannaya, Tikanna and Yerrapragada – are known as the Kavitraya ("three great poets") of Telugu. Other such translations like Marana's Markandeya Puranam, Ketana's Dasakumara Charita, Yerrapragada's Harivamsam followed. Many scientific works, like Ganitasarasangrahamu by Pavuluri Mallana and Prakirnaganitamu by Eluganti Peddana, were written in the 12th century.[citation needed]
