I don't really know if you can call Icarus a hero. Icarus was the son of Dedalus...both human. Dedalus was the genius who created the labyrinth where the minator was kept. He escaped with his son by creating wax wings, but Icarus flew too close to the sun and plunged into the Icarian sea.I like the fallen hero's. Prometheus, Icarus and Sisyphus.
Nike is an interesting goddess, though it would seem that she isn't a very popular one; there aren't many stories featuring Nike aside from when she is accompanying Minerva during battles. I think that the most beautiful image of them together is the recreation of the golden statue in Ancient Athens' Parthenon of Minerva holding Nike in her hand. I think it was actually shown in the movie Percy Jackson.My favorite Greek deity is the winged goddess Victory, called the Nike. Nike, the company, derived their name from her but it is pronounced different. The Nike would fly down and alight on a ship during a major naval battle and announce the victor. Her image is also supposedly where we get our imagery of angels in Judeo-Christian art. The most famous example of the Nike in art is the Nike of Samothrace currently housed in the Louvre. Give it a google, she's wonderful.
