[254] I understood, etc.: From the nature of the punishment, which, like all the others invented by Dante, bears some relation to the sin to which it is assigned. They who on earth failed to exercise self-restraint are beaten hither and thither by every wind that blows; and, as once they were blinded by passion, so now they see nothing plainly in that dim and obscure place. That Dante should assign the least grievous punishment of all to this sin throws light upon his views of life. In his eyes it had more than any other the excuse of natural bent, and had least of malice. Here, it must be remarked, are no seducers. For them a lower depth is reserved (Inf. xviii. See also Purg. xxvii. 15).

[255] The cranes: ‘The cranes are a kind of bird that go in a troop, as cavaliers go to battle, following one another in single file. And one of them goes always in front as their gonfalonier, guiding and leading them with its voice’ (Brunetto Latini, Tesoro, v. 27).

[256] What folk are these: The general crowd of sinners guilty of unlawful love are described as being close packed like starlings. The other troop, who go in single file like cranes, are those regarding whom Dante specially inquires; and they prove to be the nobler sort of sinners—lovers with something tragic or pathetic in their fate.

[257] The next: Dido, perhaps not named by Virgil because to him she owed her fame. For love of Æneas she broke the vow of perpetual chastity made on the tomb of her husband.

[258] At the last, etc.: Achilles, when about to espouse Polyxena, and when off his guard, was slain.

[259] Paris ... and Tristram: Paris of Troy, and the Tristram of King Arthur’s Table.

[260] So light: Denoting the violence of the passion to which they had succumbed.

[261] If none: If no Superior Power.

[262] Doves: The motion of the tempest-driven shades is compared to the flight of birds—starlings, cranes, and doves. This last simile prepares us for the tenderness of Francesca’s tale.

[263] Dido: Has been already indicated, and is now named. This association of the two lovers with Virgil’s Dido is a further delicate touch to engage our sympathy; for her love, though illicit, was the infirmity of a noble heart.
