Homer's mythical Greek hero (8)
I believe the answer is:
odysseus
'homer's mythical greek hero' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for odysseus that I've seen before include "Legendary Greek king" , "Greek name for Ulysses" , "Hero of an epic poem attributed to Homer" , "Homer's wandering hero" , "Greek hero of an epic journey home from Troy" .)
