Commentary Purg XX 97-102

To answer Dante's second question, caused by his sense that only one penitent seemed to be crying out the names of the generous, Hugh is equally contorted and long-winded, only clearing up Dante's miscomprehension at [Purg XX 118-123].  When he uttered the name of Mary ([Purg XX 19]) he did what he and his companions do during the day, i.e., name the exemplars of generous lives; at night they turn from names that serve as 'goads' to those that serve as 'bridles,' those of the avaricious.

      For Mary as 'bride of the Holy Spirit,' Singleton (DDP Singleton.Purg.XX.97-98) cites Matthew 1:20: 'For that which is begotten of her is of the Holy Spirit.'
