The seventh pit is appointed for the punishment of thieves. Serpents and dragons are here introduced. In some cases the body is reduced to ashes in consequence of the bite, and presently recovers its shape; in others man and serpent blend; in others, again, they exchange natures, the sinners themselves being transmuted into the reptiles, and becoming the instruments of torment to their fellows. A kind of reckless and brutal joviality seems to characterise the malefactors whom we meet with in this region. Among them are many Florentines, a fact which prompts Dante to an apostrophe full of bitter irony, with which Canto xxvi. opens. In the following pit a curious change of tone is manifest. The image chosen to illustrate the scene is an agreeable one--fireflies flitting in summer about a mountain valley; and the punishment though terrible is in no way loathsome or degrading, like most of those which have hitherto been described in the present circle. The sinners, too, who are mentioned are men who on earth had played heroic parts; the manner of their speech is dignified, and Dante treats them with respect. They are those who have sinned by giving wicked counsel to others, and so leading them to commit sin; and the two who are especially distinguished and who relate their stories at length are Ulysses (Canto xxvi.) and Count Guy of Montefeltro, a great Ghibeline leader (xxvii.). The former probably owes his place here to Virgil’s epithet _scelerum inventor_, deviser of crimes. In a passage which has deservedly become famous, he gratifies Dante’s curiosity as to the manner of his end. The passage, apart from its poetic beauty, is remarkable as being, so far as can be traced, due entirely to the poet’s own invention. At all events, beyond two or three words in the _Odyssey_, nothing in either classical or mediæval legend is known which can have given the suggestion for it. In the case of the Count of Montefeltro, who is alleged to have given treacherous counsel to Boniface VIII., it also appears difficult to understand how the facts, if facts they are, became known to Dante. Villani no doubt gives the story, but in language so similar to that of the poem that a suspicion arises whether he may not be relying on it as his authority.
