Odysseus blinds the cyclops with a sharpened spear. They escape by attaching themselves to the bottom of the sheep. The cyclops is feeling the ground but does not hurt the sheep because he loves them. So when the Cyclops feels the tops of the sheep, he lets them go, letting Odysseus and his men go in the process.
He uses it to stab the Cyclops in the eye so him and his crew could later escape.
The entrance to the cave of Polyphemus is blocked by a gigantic stone, that him and his entire crew couldn't move. If Polyphemus were to be killed, then his entire crew would be trapped in the cave.
Odysseus blinded Polyphemus so that him and his men could escape.
In the Odyssey, the 72 men were killed by the Cyclops named Polyphemus. Odysseus and his crew became trapped in the Cyclops' cave, and to escape, they blinded Polyphemus. As a result, the enraged Cyclops killed some of Odysseus' men as they were leaving the island.
When Odysseus reaches the land of the Cyclops, his responsibilities are to protect his crew, find a way to escape the Cyclops Polyphemus, and ensure the safe return home of himself and his men. This includes devising a plan to blind Polyphemus and then escape from his cave without being caught.
Odysseus and the crew rescue themselves from the cyclops. Odysseus later escapes under Polyphemus' largest ram.
In "The Odyssey," Odysseus demonstrates his cleverness by figuring out a way to escape the Cyclops that wants to eat them. He first stabs the monster in its one eye, then he and his crew wrap themselves in sheepskins. This allowed escape because the Cyclops thought they were just his livestock.
Odysseus blind the Cyclops. The way he does this, is that he had seen some large logs burning in the cave. So, Odysseus and his crew had managed to lift up one of the logs and shove the burning end of the log into the eye of the Cyclops, which does NOT kill him, but does blind him.
Polyphemus
Odysseus escaped the Cyclops by offering him wine to drink. The Cyclops got drunk and passed out and Odysseus and his men then fled.
The Cyclops Polyphemus starts a conversation with Odysseus and his men, asking who they are, where they are from, and what they are doing in his cave.
Odysseus and his crew went into the cyclop's cave. They drank his wine and ate his food. Then, they finally discovered that the cyclops (or Polyphemus) lived here. The cyclops was first angry, but Odysseus offered him some wine to lull him to sleep. Soon after, Polyphemus asked Odysseus what his name was and Odysseus replied that his name was "Nobody". After the cyclops had fallen asleep, Odysseus and his crew sharpened a large stick and jammed it into Polyphemus' eye. He started bumbling around blind and yelled out to his fellow cyclopes that Nobody had attacked him. The crew tied themselves to the belly of the sheep that were in the cave and made a narrow escape through Polyphemus' legs. Then, Polyphemus called to his father, Poseiden.
