Already in the fifth century BC, Pindar had mentioned a cult of Achilles on a "bright island" (φαεννά νᾶσος, phaenná nâsos) of the Black Sea, while in another of his works, Pindar would retell the story of the immortalized Achilles living on a geographically indefinite Island of the Blest together with other heroes such as his father Peleus and Cadmus.
