v. 123. Cain with fork of thorns.] By Cain and the thorns, or what is still vulgarly called the Man in the Moon, the Poet denotes that luminary. The same superstition is alluded to in the Paradise, Canto II. 52. The curious reader may consult Brand on Popular Antiquities, 4to. 1813. vol. ii. p. 476.

CANTO XXI

v. 7. In the Venetians’ arsenal.] Compare Ruccellai, Le Api, 165, and Dryden’s Annus Mirabilis, st. 146, &c.

v. 37. One of Santa Zita’s elders.] The elders or chief magistrates of Lucca, where Santa Zita was held in especial veneration. The name of this sinner is supposed to have been Martino Botaio.

v. 40. Except Bonturo, barterers.] This is said ironically of Bonturo de’ Dati. By barterers are meant peculators, of every description; all who traffic the interests of the public for their own private advantage.

v. 48. Is other swimming than in Serchio’s wave.]

Qui si nuota altrimenti che nel Serchio.
Serchio is the river that flows by Lucca. So Pulci, Morg. Mag.

Qui si nuota nel sangue, e non nel Serchio.

v. 92. From Caprona.] The surrender of the castle of Caprona to the combined forces of Florence and Lucca, on condition that the garrison should march out in safety, to which event Dante was a witness, took place in 1290. See G. Villani, Hist. l. vii. c. 136.

v. 109. Yesterday.] This passage fixes the era of Dante’s descent at Good Friday, in the year 1300 (34 years from our blessed Lord’s incarnation being added to 1266), and at the thirty-fifth year of our poet’s age. See Canto I. v. 1.
