The story of Aristæus, which closes the fourth Georgic, is the most beautiful of the Latin epyllia. Embodying, as it does, Vergil’s most finished work in the epic style, it has at once the technical perfection, which the Peleus and Thetis lacks, and the poetic beauty of Vergil’s greatest period. So direct is the narrative and so great the charm that it is almost a shock to the critic to discover that it is constructed on the lines of the formal epyllion, and is a genuine product of Alexandria. It is, in fact, an Alexandrian epyllion transfigured by that undefinable quality which constitutes the genius of Vergil.
