What's the Meaning of Immortality?

I think an artist also, whether they're conscious of it or not, they seek to attain immortality through their work. To be able to create the piece that's going to transcend their own short little lifespan. Like Elysses in Homer's Odyssey. The idea is he only went on his whole adventure because he was so longing with homesickness for his native land of Ithaca. That's what makes the epic poetry happen.
