Cyclops strength vs Odysseus and his men

After a time, a Cyclops, whose name was Polyphemus, returned to the cave. Leading his flock of giant sheep into the cave, he rolled a huge stone against the mouth of the cave to close the entrance. On finding Odysseus and his men in the cave, the Cyclops became enraged, grabbed two of the men, smashed their heads against the rocks, ate them, and fell asleep. Odysseus dared do nothing to the Cyclops, since only the Cyclops was strong enough to move the stone away from the mouth of the cave.
