Commentary Inf X 60

Cavalcante's mournful question about his son's whereabouts has reminded some commentators (perhaps the first was Daniello, in 1568 [DDP Daniello.Inf.X.52-63]) of Andromache's equally mournful question about the whereabouts of her husband Hector, 'Hector ubi est?' (Aen III.312). But see Durling (Durl.1981.2), p. 25n., arguing for the resonance of Genesis 4:9: 'Ubi est Abel frater tuus?' (Where is Abel your brother?). Durling points out that both these 'fratricidal' stories culminate in an exile, Cain sent forth from the land a fugitive (Gen. 4:12-16), while Guido was literally sent into exile by the action of Dante and the five other Priors of Florence.
