Lonnie's right - The Odyssey is the story of Odysseus's wanderings on his way home to Ithaca after the Trojan War. Homer's only account of the Trojan War ( and hence the siege) is The Iliad - which ain't 7 letters. Where did the question come from? Maybe the questioner has some wires crossed....?
Well done, Fibonacci - I should have thought of that as I'm actually learning modern Greek! I should also have read the question more carefully......:-)
