Tamil literature and Tamil epics and classics have many references to Vedic gods and culture. The Tolkaappiyam, 1st century BCE grammar book, mentions non-Vedic, early-Vedic (Indra, Varuna) and Puranic (Vishnu) gods. The Paripadal (8; 3; 9 etc.), one of the Eight Anthologies of poetry (or ettuttokai), has homages to Vishnu, Lakshmi, Brahma, the twelve Adityas, the Ashvins, the Rudras, the Saptarishis, Indra, the Devas etc. The Kural, written by Tiruvalluvar, mentions gods like Indra (25) and Lakshmi (e.g. 167).
