(Epist. i. p. 664.) This proximity of the Lombards is hard of digestion. Camillo Pellegrini (Dissert. iv. de Ducatu Beneventi, in the Script. Ital. tom. v. p. 172, 173) forcibly reckons the 14th stadia, not from Rome, but from the limits of the Roman duchy, to the first fortress, perhaps Sora, of the Lombards. I rather believe that Gregory, with the pedantry of the age, employs stadia for miles, without much inquiry into the genuine measure.
