Homer's work one day will enthral storyteller briefly (5)
I believe the answer is:
iliad
'homer's work' is the definition.
(I've seen this before)
'one day will enthral storyteller briefly' is the wordplay.
I cannot really understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
'day' could be 'd' (abbreviation for day) and 'd' is present in the answer.
The remaining letters 'lia' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for iliad that I've seen before include "Old story" , "Epic piece of writing" , "Homer's tale" , "The -----, Homeric epic" , "Great poem by Homer" .)
