Note 539 — CANTO XIX.
James Romanes Sibbald translation
Like a friar, etc.: In those times the punishment of an assassin was to be stuck head downward in a pit, and then to have earth slowly shovelled in till he was suffocated. Dante bends down, the better to hear what the sinner has to say, like a friar recalled by the felon on the pretence that he has something to add to his confession.
