Dear list members,
Is anyone familiar with local (pre-modern) traditions, textual, ritual or other, involving Purūravas (with or without Urvaśī)?

In addition, I'm searching for the origin of the phrase "āṟu cakkiravartti",  "The Six Emperors" (Tamiḻ), a list which has some variations but usually includes Nala, Pururavas, Ariccantiran and frequently Mucukuntan and Karttaviriyan?

Thank you,
