Note 649 — CANTO XXV.
James Romanes Sibbald translation
The robber, etc.: By means of his prophecy Fucci has, after a fashion, taken revenge on Dante for being found by him among the cheating thieves instead of among the nobler sinners guilty of blood and violence. But in the rage of his wounded pride he must insult even Heaven, and this he does by using the most contemptuous gesture in an Italian’s repertory. The fig is made by thrusting the thumb between the next two fingers. In the English ‘A fig for him!’ we have a reference to the gesture.
