Tirumular, also known as Suntaranāthar, was a TamilShaivite mystic and writer, considered one of the sixty-three poet-saints called the Nayanars, and is listed among a group of 18 sages called the Siddhars. His magnum opus, the ''Tirumantiram'', consisting of over 3000 verses, forms a part of the key text of the Tamil Shaiva Siddhanta compilation called the ''Tirumurai''.
