What is the theme of the test of the great bow?

The theme is for Penelope to find her house band or who the man she will marry is. The only problem is that she knows that no one will be able to do it except for Odysseus. But she had no idea that he was actually there. Odysseus had gone through all of that trouble and the long travel to reunite with his lovely wife Penelope and now here she is giving a test out to the men to choose which one she would marry. Odysseus wasn't very happy when he saw what was happening, but little did he know that Penelope has no intention of marry any of those guys. In fact, she doesn't want to marry any of them, that's why she chose a challenge that only Odysseus could have done.
