"As for the stranger, though,
the man’s an old family friend, from Taphos,
wise Anchialus’ son. He says his name is Mentes,
lord of the Taphian men who love their oars."
So he said
but deep in his mind he knew the immortal goddess.

– Homer

The Odyssey, Book 1, lines 475-479. When Eurymachus questions Telemachus on who his guest is, Telemachus answers that his name is Mentes. Telemachus, aware that Mentes is the disguised goddess Athena, shows cunning by hiding her real identity from the suitors.
