Note 698 — CANTO XXVII.
James Romanes Sibbald translation
Over the city, etc.: Forlì. The reference is to one of the most brilliant feats of war performed by Guido of Montefeltro. Frenchmen formed great part of an army sent in 1282 against Forlì by the Pope, Martin IV., himself a Frenchman. Guido, then lord of the city, led them into a trap and overthrew them with great slaughter. Like most men of his time Guido was a believer in astrology, and is said on this occasion to have acted on the counsel of Guido Bonatti, mentioned among the diviners in the Fourth Bolgia (Inf. xx. 118).
