According to Jain tradition, which some think is supported by inscriptions at Śravana-Beḷgoḷa,[527] Bhadrabâhu accompanied by Candra Gupta (identified with the Maurya king of that name) led a migration of Jains from the north to Mysore about 300 B.C. The authenticity of this tradition has been much criticized but it can hardly be disputed that Jainism came to southern India about the same time as Buddhism and had there an equally vigorous and even longer existence. Most Tamil scholars are agreed in referring the oldest Tamil literature to the first three centuries of our era and I see nothing improbable in this. We know that Asoka introduced Buddhism into south India. About the time of the Christian era there are many indications that it was a civilized country[528] which maintained commercial relations with Rome and it is reasonable to suppose that it had a literature. According to native tradition there were three successive Sanghams, or Academies, at Madura. The two earlier appear to be mythical, but the third has some historical basis, although it is probable that poems belonging to several centuries have been associated with it. Among those which have been plausibly referred to the second century A.D. are the two narrative poems Śilappadhikaram and Manimêkhalai as well as the celebrated collection of didactic verses known as the Kural. The first two poems, especially the Manimêkhalai, are Buddhist in tone. The Kural is ethical rather than religious, it hardly mentions the deity,[529] shows no interest in Brahmanic philosophy or ritual and extols a householder's life above an ascetic's. The Nâladiyâr is an anthology of somewhat similar Jain poems which as a collection is said to date from the eighth century, though verses in it may be older. This Jain and Buddhist literature does not appear to have attained any religious importance or to have been regarded as even quasi-canonical, but the Dravidian Hindus produced two large collections of sacred works, one Śivaite the other Vishnuite, which in popular esteem rival the sanctity of the Vedas. Both consist of hymns, attributed to a succession of saints and still sung in the temple worship, and in both sects the saints are followed by a series of teachers and philosophers. We will take the Śivaites first. 3
