Homeric work one mislaid? (5)

I believe the answer is:

iliad

I'm a little stuck... Click here to teach me more about this clue!

'homeric work' is the definition.
(I've seen this in another clue)

I don't understand how the rest of the clue works.

(Other definitions for iliad that I've seen before include "A work by 7" , "Homer's tale" , "Homer's great poem" , "Classic" , "Work on war" .)

I've seen this clue in the Evening Standard.
