It is also like the story of Odysseus that I told you about in your other thread about the tapestry. My exact post was this:
"As for Odysseus, his first attempt to leave Calypso's island was by a raft he built. He fought with many natives on the lands he visited because all of them for some reason didn't let him leave. The most importand thing it must be that in order to find his way home he had to overcome his arrogance and pride, 2 things that got him in trouble with Poseidon. And last, about the tapestry Odysseus had the help of Zeus and Athena, thus the writting about God's giving you what your heart desires. His only desire was to go back home. I know I probably bored you with all this mythological refferances (we Greeks love our mythology!) but I had to in order to show my point. The losties will find the way home with the help of Jacob (he who will save us all?) only if they overcome their bad side of themselves and in the end make the right choice. I think that is the connection, since Jacob is pro free will and the progress that is made through the journey."
In most Greek myths we have people struggling their way home, overcoming obstacles and by the help of s'one and of course by never losing hope they manage to get their purpose fulfilled.
