Commentary Purg XXX 109-114

Pietrobono (DDP Pietrobono.Purg.XXX.109-111) points out that in Convivio (Conv.IV.xxi.7-8) Dante had already revealed his theory of the relationship among the elements of the individual human soul: the fathering sower, the embryo, and the astral influences of the constellations of the zodiac that shape its human talents.  In this passage we hear about God, who breathes in last the vital element, the intellectual, or rational, soul.  The passage at [Purg XXV 68-75] explains that the generation of the rational soul is performed directly by God; here we learn that not even the saved in the Empyrean nor the angels can understand the love that moves God in the creation of that soul in each of his human creatures.
