Protracted works (5)
I believe the answer is:
epics
'protracted works' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for epics that I've seen before include "Spice up with adventurous poems or stories" , "Long narrative poems telling of deeds of heroes" , "Long poems about great events" , "Long tales of heroic deeds" .)
