Commentary Purg XXIV 16-18

'Here' surely refers to this terrace (see C.Purg.XXII.49-51).  Since there is no prohibition against naming names on any other terrace, commentators worry about Forese's motive in speaking this way.  Most currently agree that he is using exaggerated understatement (the trope litotes) to make his point: i.e., on this terrace one must use names to identify the penitents because they are unrecognizable (as was Forese to Dante at [Purg XXIII 43-48]) as a result of their emaciation.
