Periyalvar Tirumoli

The Periyalvar Tirumoli (பெரியாழ்வார் திருமொழி) is a Tamil Hindu work of literature written by Periyalvar, one of the twelve Alvars, the poet-saints of Sri Vaishnavism. Comprising 473 verses, it is part of the compendium of hymns called the Nalayira Divya Prabandham, dating back to the 9th century CE.

Hymns
A hymn of the Periyalvar Tirumoli describes the temple of Srirangam as the home of the Dashavatara, as translated by Vasudha Narayanan:

"This is the temple of him who became the divine fish, tortoise, boar, lion, and dwarf. He became Rama in three forms, he became Kanna, and as Kalki, he will end [these worlds]."Periyalvar also extols Krishna's act of lifting the mountain, Govardhana: "Like the king of the serpents opening his many hoods and supporting the vast worlds on it, The five fingers of Damodara's hand opened like the petals of a flower and held aloft Govardhana."
