Sundarar (
Tamil Cundarar), also known affectionately as
Tampiran Tōḻan (
Comrade of the Master, meaning
Shiva) was an eighth-century poet who was one of the most prominent
Nayanars, the
Shaiva bhakti (devotional) poets of
Tamil Nadu. He was a contemporary of
Cheraman Perumal and
Kotpuli Nayanar who also figure in the 63 Nayanmars. The songs of praise are called Thiruthondathogai and is the original nucleus around which the
Periyapuranam is based. The
Periya Puranam, which collects the legends of the Nayanars, starts and ends with him. The hymns of seventh volume of the
Tirumurai, the twelve-volume compendium of the poetry of Tamil
Shaiva Siddhanta, were composed by him.
