Thatha.--Thathan is the name given to mendicants who profess Vaishnavism. Such Paraiyans are Vaishnavites, and some are beggars. In the Census Report, 1901, Mr. Francis notes that the term Paraiyan "is now almost a generic one, and the caste is split up into many sub-divisions, which differ in manners and ways. For example, the Koliyans, who are weavers, and the Valluvans, who are medicine men and priests and wear the sacred thread, will not intermarry or eat with the others, and are now practically distinct castes." As occupational titles of Paraiyans Mr. Francis gives Urumikkaran and Pambaikkaran, or those who play on drums (urumi and pambai), and Podarayan or Podara Vannan, who are washermen. The title Valangamattan, or people of the right-hand division, is assumed by some Paraiyans. Mr. Clayton states that he knows of no legend or popular belief among the Paraiyans, indicating that they believe themselves to have come from any other part of the country than that where they now find themselves. There is, however, some evidence that the race has had a long past, and one in which they had independence, and possibly great importance in the peninsula. Mr. Stuart mentions [52] that the Valluvans were priests to the Pallava kings before the introduction of the Brahmans, and even for some time after it. He quotes an unpublished Vatteluttu inscription, believed to be of the ninth century, in which it is noted that "Sri Valluvam Puvanavan, the Uvacchan (or temple ministrant), will employ six men daily, and do the temple service." The inference is that the Valluvan was a man of recognised priestly rank, and of great influence. The prefix Sri is a notable honorific. By itself this inscription would prove little, but the whole legendary history of the greatest of all Tamil poets, Tiruvalluvar, "the holy Valluvan," confirms all that can be deduced from it. His date can only be fixed approximately, but it is probable that he flourished not later than the tenth century A.D. It is safe to say that this extraordinary sage could not have attained the fame he did, or have received the honours that were bestowed upon him, had not the Valluvans, and therefore the Paraiyans, been in the circle of respectable society in his day. This conjecture is strengthened by the legend that he married a Vellala girl. The same hypothesis is the only one that will account for the education and the vogue of the sister of the poet, the aphoristic poetess Avvei. In the Census Report, 1901, Mr. Francis mentions an inscription of the Chola King Raja Raja, dated about the eleventh century A.D., in which the Paraiyan caste is called by its own name. It had then two sub-divisions, the Nesavu or weavers, and Ulavu or ploughmen. The caste had even then its own hamlets, wells and burning-grounds.
