Telemus

Telemus (Greek: Τήλεμος Telemos) was a figure of Greek mythology, a prophet, son of Eurymus. Telemus warned the Cyclops Polyphemus that he would lose his sight to a man named Odysseus.

'Alas!
Now an ancient prophecy about me
has truly been fulfilled! Telemus,
fine, tall son of Eurymus, a seer
who surpassed all men in prophecy,
reached old age among the Cyclopes
as a soothsayer. He said all these things
would come to pass someday—I'd lose my sight
at the hand of someone called Odysseus.
