As Aeneas continues his underworld journey, his father Anchises shows him the future Marcellus, tragic nephew and adopted son and heir of the Emperor Augustus, whose great promise will be cut short by death at the age of nineteen.

The illustration reflects the tradition that Marcellus’s mother, Octavia, was so moved at hearing Virgil recite this passage that she fainted dead away.
