"The courtesan who never from the dwelling Of Caesar turned aside her strumpet eyes, Death universal and the vice of courts, Inflamed against me all the other minds, And they, inflamed, did so inflame Augustus"

(Canto 13, lines 64-68)

The "courtesan" is probably the envy that Dante is so fond of blaming for almost every evil on earth. The circular, formal diction in Pier's monologue has often been viewed as a conscious imitation of his personality in life - here he uses both Caesar and Augustus in place of Frederick's name.
