Epic of a wanderer
I believe the answer is:
aeneid
'epic of a wanderer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aeneid that I've seen before include "Virgil narrative poem" , "Virgil's epic Latin poem" , "epic from the past" , "1 28 [EPIC POEM]" , "Work" .)
