Overview
The period of writing of the poem is believed to be between the beginning and the end of the 13th century. From the references in this work itself, Ulloor postulates that the Unniachicharitam must have been written before 1346 AD. The theme of Unniyachi Charitham is the infatuation of a Gandharvan with Unniyachi, the younger of the two daughters of Nangaiah's daughter Achiyar, who came from Atiyamanallur in Salem to Kolathunath and from there to Tirumaruthur in Purakizhanadu (present Kottayam).
