epyllion (plural epyllia)
- (literary) a "little epic".
- (literary) A brief narrative poem with a romantic or mythological theme.
It refers primarily to the type of erotic and mythological long elegy of which Ovid remains the master; to a lesser degree, the term includes some poems of the English Renaissance, particularly those influenced by Ovid. An example of a classical epyllion may be seen in the story of Nisus and Euryalus in Book IX of The Aeneid.
