Archaeology
Archaeology has found epigraphic evidence of the early Cheras in the recorded history of South India: some inscriptions trace the dynasty even from the mythical Puranic kings of the Lunar dynasty. Two identical inscriptions at Pugalur dated to 2nd century describe three generations of Chera rulers of the Irumporai clan. They record the construction of a rock shelter for Jains on the occasion of the investiture of the Crown Prince Ilam Kadungo, son of Perum Kadungo, and the grandson of Athan Cheral Irumporai (perhaps Selva Kadumko Valiathan). Inscriptions found at Edakkal Caves, Wynad also describes the Cheras as "kadummipudha chera". The Aranttar Malai iscription at Pugalur, Tamil Nadu assigned by historians to the 1st century AD mentions three generations of Chera kings.
