Nanmukan Tiruvantati

The Nanmukan Tiruvantati is a Tamil Hindu work of literature composed by Tirumalisai Alvar, one of the twelve Alvars of Sri Vaishnavism. Comprising 100 verses in the form of a poetic device known as the antati, it is part of the compendium of hymns called the Nalayira Divya Prabandham. It is dedicated to the preserver deity, Vishnu.
Scholars have posited that the primary purpose of the Nanmukan Tiruvantati was to establish the supremacy of Narayana over Nanmukan and Shankaran.
