How does Odysseus escape Polyphemus's cave in the odyssey?

Odysseus escapes Polyphemus's cave by employing cunning and trickery. He tells the Cyclops that his name is "Nobody," so when he blinds Polyphemus with a sharpened stake, the giant's cries for help go unheard, as he claims that "Nobody" is attacking him. To flee the cave, Odysseus and his men hide under the sheep as Polyphemus lets them out to graze, allowing them to escape unnoticed. Once they are safely at sea, Odysseus reveals his true identity, provoking Polyphemus's wrath.
