Penelope announces a challenge for the suitors and whoever wins gets to have Penelope as their wife. Odysseus, disguised as an old beggar, wins the challenge, reveals himself to the suitors, and then commits mass murder on all of them.
"...I am about to hold a contest. My husband would sometimes set out twelve axes all in a row... Now I will make the suitors compete in this contest. Whichever of them most easily strings the bow and shoots an arrow through all twelve axes-with that man I will go..."(19.570-571,575-578.)
"So give him the bow. Let us see what he will do. I promise that if Apollo grants him the honor of stringing it, I will give him a handsome cloak and tunic..." (21.326-330).
"...And sure in his aim he let go of it, and the arrow flew straight through the holes of each of the twelve axes, from first to last, not missing one of them."(21.411-414).
"The contest is over, gentleman. Now I will see how well I can do with another target, which no one has thought of yet. With Apollo's help I will hit it" (22.4-6).
"But Odysseus shot, and the arrow went for his throat, and the bronze point tore its way through the tender flesh of the neck"(22.13-15).
"...Her knees went limp and her heart melted, and after he finished, She burst into tears and ran up to him and threw her arms around him and kissed his face" (23.174-176).
