Which done, he discovered himself to Sordello, and said, ‘Enough; abstain in future from doing so foul a deed in so foul a place.’ Sordello, terrified, humbly besought pardon; promising never more to return to his sister. But the accursed Cunizza again enticed him into his former error. Wherefore, fearing Ezzelino, the most formidable man of his time, he left the city. But Ezzelino, as some say, afterwards had him put to death.” He says, moreover, that Dante places Sordello alone and separate from the others, like Saladin in Inferno IV 129, on account of his superiority, or because he wrote a book entitled “The Treasure of Treasures”; and that Sordello was a Mantuan of the village of Goïto⁠—“beautiful of person, valiant of spirit, gentle of manner.” Finally, Quadrio, Storia d’ogni Poesia , II 130, easily cuts the knot which no one can untie; but unfortunately he does not give his authorities.
