Ramavataram, popularly referred to as Kamba Ramayanam, is a Tamil epic that was written by the Tamil poet Kambar during the 12th century. Based on Valmiki's Ramayana (which is in Sanskrit), the story describes the life of King Rama of Ayodhya. However, Ramavatharam is different from the Sanskrit version in many aspects – both in spiritual concepts and in the specifics of the storyline.
