Madhurakavi Alvar is one of the twelve azhwar saints of South India, who are known for their affiliation to Vaishnava tradition of Hinduism. Mathurakavi is considered the sixth in the line of the twelve azhwars. He was the disciple of Nammazhwar, considered the greatest among the twelve azhwars, and his contributions amount to 11 among the 4000 stanzas in the Nalayira Divya Prabandam. Mathurakavi is believed to have recorded and compiled the works of Nammazhwar namely, Thiruvaymozhi (1102 verses). One can say that the 11 verses of Kanninun Siru Thambu composed by Swami Madhurakavi Alvar can be considered as the key which opened the treasure to the 4000 verses of Nalayira Divya Prabandham.
