Commentary Inf V 100-106
The use of anaphora (repetition) here at the beginning of each tercet, 'Amor... Amor... Amor...,' underlines the rhetorical skill of Francesca, who presses her case with listening Dante: it was Love's fault that she and Paolo fell into carnal passion. 'Amor' appears three times as the first word in a tercet after an end-stopped line and thus must be capitalized. It seems also reasonable to believe that Francesca is here referring to her 'god,' the Lord of Love, Cupid, whose name is 'Amor.' He is the only god she seems to own, since, by her account ([Inf V 91]), the 'King of the universe' is not her friend.
