From Inferno: Canto XXII:
Ever upon the pitch was my intent, To see the whole condition of that Bolgia, And of the people who therein were burned. So upon every side the sinners stood; But ever as Barbariccia near them came, Thus underneath the boiling they withdrew. I saw, and still my heart doth shudder at it, One waiting thus, even as it comes to pass One frog remains, and down another dives; And Graffiacan, who most confronted him, Grappled him by his tresses smeared with pitch, And drew him up, so that he seemed an otter. I knew, before, the names of all of them, So had I noted them when they were chosen, And when they called each other, listened how. "O Rubicante, see that thou do lay Thy claws upon him, so that thou mayst flay him," Cried all together the accursed ones. And I: "My Master, see to it, if thou canst, That thou mayst know who is the luckless wight, Thus come into his adversaries' hands." Near to the side of him my Leader drew, Asked of him whence he was; and he replied: "I in the kingdom of Navarre was born; My mother placed me servant to a lord, For she had borne me to a ribald knave, Destroyer of himself and of his things. Then I domestic was of good King Thibault; I set me there to practise barratry, For which I pay the reckoning in this heat." Infuriate at the mockery, Calcabrina Flying behind him followed close, desirous The other should escape, to have a quarrel. And when the barrator had disappeared, He turned his talons upon his companion, And grappled with him right above the moat. But sooth the other was a doughty sparhawk To clapper-claw him well; and both of them Fell in the middle of the boiling pond. A sudden intercessor was the heat; But ne'ertheless of rising there was naught, To such degree they had their wings belimed. Lamenting with the others, Barbariccia Made four of them fly to the other side With all their gaffs, and very speedily This side and that they to their posts descended; They stretched their hooks towards the pitch-ensnared, Who were already baked within the crust, And in this manner busied did we leave them.
