"Then he cunningly made his wife offer his bow and a quantity of iron to be contended for by us ill-fated suitors; and this was the beginning of our end, for not one of us could string the bow- nor nearly do so. When it was about to reach the hands of Ulysses, we all of us shouted out that it should not be given him, no matter what he might say, but Telemachus insisted on his having it. When he had got it in his hands he strung it with ease and sent his arrow through the iron. Then he stood on the floor of the cloister and poured his arrows on the ground, glaring fiercely about him. First he killed Antinous, and then, aiming straight before him, he let fly his deadly darts and they fell thick on one another. It was plain that some one of the gods was helping them, for they fell upon us with might and main throughout the cloisters, and there was a hideous sound of groaning as our brains were being battered in, and the ground seethed with our blood. This, Agamemnon, is how we came by our end, and our bodies are lying still un-cared for in the house of Ulysses, for our friends at home do not yet know what has happened, so that they cannot lay us out and wash the black blood from our wounds, making moan over us according to the offices due to the departed."
