Tallapaka is a village in Rajampet mandal of Kadapa district. The village is famous for being the birth place of renowned Saint, Annamacharya, who is believed to be the incarnation of Lord Venkateshwara's Nandaka or Sword. His bountiful contributions for Telugu literature doubled the fame of Tallapaka. There are poems called as "Dwipada", written by Tallapaka Chinnanna, grandson of Annamacharya, which highlights the life and work of this great saint.
Annamacharya is the earliest known musician to compose devotional songs on Lord Venkateshwara in Telugu and who also made invaluable contribution to music and literature, during 15th century. He composed more than thirty two thousand "Sankeerthanas" or Sacred Hymns, on palm leaves, in praise of Lord Venkateshwara, which were later engraved on copper plates by his son Tirumalacharya. Most of these copper plates lay unnoticed for nearly 400 years in a rock built cell opposite to the Hundi in the Tirumala Temple. About twenty five hundred copper plates, comprising of about fourteen thousand Sankeerthanas were found in the year 1922.
