Several Tamil literary works, such as Iraiyanar Akapporul, mention the legend of three separate Tamil Sangams lasting several centuries before the Christian Era and ascribe their patronage to the Pandyas. The Sangam poem "Maduraikkanci" by Mankudi Maruthanaar contains a full-length description of Madurai and the Pandyan country under the rule of Nedunjeliyan II. The "Nedunalvadai" by Nakkirar contains a description of the king's palace. The "Purananuru" and "Agananuru" collections of the third century BCE contain poems sung in praise of various Pandyan kings and also poems that were composed by the kings themselves. "Kaliththokai" mentions that many Dravidian tribes such as Maravar, Eyinar, Oliar, Oviar, Aruvalur and Parathavar migrated to the Pandyan kingdom and started living there in the Third Tamil Sangam period 2000 years ago.
