Odysseus returns successfully to Ithaca to reclaim his throne and his family. He triumphed over many challenges and never gave up on his family. His return shows how important family was to the Greeks and how necessary it is to never give up.
We can see Greek family values based on Penelope who waited for Odysseus for 10 years to come home and did not want to marry any of the suitors. His Son is also always on his side and believes that he'll come back. Even his dog is faithful and is one of the rare Ithacians who recognizes him.
