Poonthanam Namboothiri (1547-1640) was a contemporary of Melpathur Bhattathiri and Ezhuthachan. He was born in Keezhattur, near Perinthalmanna in the present Malappuram District
. His chief poems in Malayalam
are Bhasha Karnamritam, Kumaraharanam (or Santanagopalam Pana) and Jnanappana. The first is a devotional work intended to create Krishna bhakti in the mind of readers, and the second is a touching narrative. Jnanappana (Song of Divine Wisdom) is a veritable storehouse of transcendental knowledge. A large number of hymns and prayer songs have been attributed to Poonthanam.
