Sangam literature, the earliest writings in the Tamil language, thought to have been produced in three chankams, or literary academies, in Madurai, India, from the 1st to the 4th century ce. The Tolkappiyam, a book of grammar and rhetoric, and eight anthologies (Ettuttokai) of poetry were compiled—Ainkurunuru, Kuruntokai, Narrinai, Akananuru, Kalittokai, Patirruppattu, Purananuru, and Paripatal. A ninth anthology, Pattupattu, consists of 10 idylls that present a picture of early Tamil life.
Sangam writings are possibly unique in early Indian literature, which is almost entirely religious. The poems are concerned with two main topics: those of the first five collections are on love (akam), and those of the next two are on heroism (puram), including the praise of kings and their deeds. Paripatal, the eighth collection, contains poems of both types. Many of the poems, especially on heroism, display great freshness and vigour and are singularly free from the literary conceits of much of the other early and medieval literatures of India. Since they deal almost entirely with nonreligious subjects, these poems are also free from the complex mythical allusions that are such an outstanding feature of most Indian art forms. There are nonetheless some instances of religious works in sangam poetry. Paripatal, for example, is believed to be a collection of 70 poems, of which only 22 remain in full today. It contains, among others, poems about Tirumal, Murugan, and the river Vaiyai (personified as a goddess).
