Commentary Par X 43-48

The brightness that Dante saw in these souls, which made them stand out from the Sun, not by being a different color, but by being even brighter than the brightest thing known to our mortal vision, simply cannot be described by the poet, outdone by God's art, as it were.  For discussion of this contrast in these lines between Dante's limited ability as artist in comparison to God's, see Barolini (Baro.1992.1), pp. 196-97.
