is feast upon the head of his foe!

"Thus having spoke,
Once more upon the wretched skull his teeth
He fasten'd like a mastiff's 'gainst the bone,
Firm and unyielding."

Dante, passing on, discovers many other victims encased in the ice,
and is so chilled by a glacial breeze that his face muscles stiffen.
He is about to ask Virgil whence this wind proceeds, when one of the
ice-encrusted victims implores him to remove its hard mask from his
face. Promising to do so in return for the man's story, Dante learns
he is a friar who, in order to rid himself of inconvenient kinsmen,
invited them all to dinner, where he suddenly uttered the fatal words
which served as a signal for hidden assassins to despatch them. When
Dante indignantly exclaims the perpetrator of this heinous deed is on
earth, the criminal admits that, although his shadow still lingers
above ground, his soul is down here in Ptolomea, undergoing the

ice, and excuses himself to his readers by stating "ill manners were
best courtesy to him." _Canto XXXIV._ Virgil now directs Dante's
glance ahead, until our poet dimly descries what looks like an immense
windmill. Placing Dante behind him to shield him a little from the
cruel blast, Virgil leads him past countless culprits, declaring they

death, Dante now beholds Dis or Satan,--Emperor of the Infernal
Regions,--sunk in ice down to his waist, and discovers that the wind
is caused by the constant flutter of his bat-like wings. He also
perceives that Satan is as much larger than the giants just seen, as
they surpass mankind, and states that, were the father of evil as fair
as he is foul, one might understand his daring to defy God.

"If he were beautiful
As he is hideous now, and yet did dare
To scowl upon his Maker, well from him
May all our misery flow."

Then Dante describes Satan's three heads, one red, one yellow and
white, and one green, declaring that the arch-fiend munches in each
mouth the sinners Judas, Cassius, and Brutus. After allowing Dante to
gaze a while at this appalling sight, Virgil informs his charge that,
having seen all, it behooves them to depart. With a brief order to
Dante to cling tightly around his neck, Virgil, seizing a moment when
