[37] In _Purg._ xxx. 109-117, Dante thus distinguishes between the _ovra de le rote magne_ and the _larghezza di grazie divine_ in his own case. St. Gregory the Great, speaking of the correspondence of men with the angelic orders, uses the phrase: _divinae largitatis munere refecti_ (_Hom. in Evangelia_, ii. 34). [38] I venture to retain this reading, although the _testo critico_ now gives: _E’n la sua volontade_. [39] The Vulgate has _virtutes caelorum_, in Matt. xxiv. and Luke xxi., where the English Bible reads “the powers of the heavens.” [40] St. John of Damascus. [41] Note the scansion of the previous line (37): _Io che al divino da l’umano_. There is no syneresis in _ïo_, no elision of the _e_ in _che_; thus emphasising Dante’s personal experience, his wonder that it should be vouchsafed to him, and producing the slow movement, the solemn intonation of the line.
