Who gave Penelope the idea of the axe head challenge?

Penelope was inspired to create the axe head challenge after observing the skill of her husband, Odysseus. When he returned home disguised as a beggar, she devised the contest using the axes that Odysseus had once owned, knowing that only he would be able to string his great bow and shoot an arrow through the axe heads. This challenge served as a means to test the suitors and ultimately reveal Odysseus's identity.
