[PAULUS libro secundo epitomarum Alfeni digestorum. ] §8.2.16.prLumen id est, ut caelum uideretur, et interest inter lumen et prospectum: nam prospectus etiam ex inferioribus locis est, lumen ex inferiore loco esse non potest.
[PAULUS in the second book of the Epitomes of Alfenus' Digest.] Light is this, that the sky is seen, and there is a difference between light and prospect: for prospect is possible even from lower places, but light cannot be from a lower place.
