The last three mentions of Boniface (in a simile concerning the panderers, by the Simonist Pope Nicholas III, and by fraudulent counselor Guido da Montefeltro) in the Inferno all point to his questionable practice of selling indulgences or absolution. Hmmm, selling the Word? Simony? This one was slightly more predictable in that Pope Nicholas III actually tells us that he’s waiting for Boniface to replace him in his fiery hole:
I stood as does the friar who confesses
the foul assassin who, fixed fast, head down,
calls back the friar, and so delays his death;
and he cried out: "Are you already standing,
already standing there, o Boniface?
The book has lied to me by several years.
Are you so quickly sated with the riches
for which you did not fear to take by guile
the Lovely Lady, then to violate her?"
And I became like those who stand as if
they have been mocked, who cannot understand
what has been said to them and can’t respond. (Inf. XIX, 49-60)
Because he couldn’t put his nemesis in Hell just yet, Dante has reserved a spot for him
