He threw the sinner down, then wheeled along
the stony cliff: no mastiff’s ever been
unleashed with so much haste to chase a thief. (Inf. XXI, 43-45)
"Mule that I was, the bestial life pleased me
and not the human; I am Vanni Fucci,
beast; and the den that suited me – Pistoia." (Inf. XXIV, 124-126)
As I kept my eyes fixed upon those sinners,
a serpent with six feet springs out against
one of the three, and clutches him completely.
It gripped his belly with its middle feet,
and with its forefeet grappled his two arms;
and then it sank its teeth in both his cheeks;
it stretched its rear feet out along his thighs
and ran its tail along between the two,
then straightened it again behind his loins.
No ivy ever gripped a tree so fast
as when that horrifying monster clasped
and intertwined the other’s limbs with its.
Then just as if their substance were warm wax,
they stuck together and they mixed their colors,
so neither seemed what he had been before; (Inf. XXV, 49-63)
