Commentary Par XXVI 64-66

Scartazzini (DDP Scartazzini.Par.XXVI.65) was apparently the first (and still among the few) to see that Dante was again resorting to the text of John's Gospel (15:1): 'Ego sum vitis vera et Pater meus agricola est' (I am the true vine, and my Father is the vinedresser).  See also Singleton (DDP Singleton.Par.XXVI.64-66), Bosco/Reggio (DDP Bosco.Par.XXVI.64-66), and Getto (Gett.1968.1), p. 941.  It is also true that none of these cites Scartazzini, or indeed anyone else.
