Ilango Adigal (Tamil: இளங்கோவடிகள்) was a Jain monk and a poet, sometimes identified as a Chera prince. He is traditionally credited as the author of Cilappatikaram, one of the Five Great Epics of Ancient Tamil literature. He is one of the greatest poets from Cheranadu (now Kerala). In a patikam (prologue) to the epic poem, he identifies himself as the brother of a famous Chera king Ceṅkuṭṭuvan (Senguttuvan). This Chera king, as stated by Elizabeth Rosen, ruled over his kingdom in late 2nd or early 3rd century CE. However, this is doubtful because a Sangam poem in Patiṟṟuppattu – the fifth ten – provides a biography of Ceṅkuṭṭuvan, his family and rule, but never mentions that he had a brother who became an ascetic or wrote one of the most cherished epics. This has led scholars to conclude
