Servius in his note on Aeneid iv. 92 comments that Virgil uses the epithet Saturnia of Iuno only ‘when she is about to do mischief, for he knows that the planet Saturn has a baleful influence’. An astrological interpretation of Virgil is doubtless interesting, but if, as none will question, Virgil is a poet before he is an astrologer, the only satisfactory explanation of an epithet is one that elucidates its poetic significance. An examination of Virgil's use of the epithet Saturnia does, I think, make it clear both that the epithet has poetic significance and that its significance is intimately bound up with Iuno's role in the poem. Her intervention in the action of the Aeneid determines that action in a way that distinguishes it from the interventions of the various gods and goddesses in the actions of the Iliad and the Odyssey, and even from the interventions of other gods in the Aeneid itself. Venus behaves in the Aeneid in much the same way as the Homeric gods and goddesses do. She is at hand to perform little miracles for her son, as Athena was at hand to help Odysseus or Telemachus. Now it is a striking fact that the epithets used of Venus in the Aeneid have no special significance. On twenty-one occasions she is referred to as Venus without an epithet, once she is Venus aurea, and four times she is Cytherea. These are all conventional, and agree well with the conventional nature of Venus' intervention in the action.
