Thus again, the evening star is the most beautiful of the stars: cf. Bion. xvi. 1: ῞Εσπερε, κυανέας ἱερὸν, φίλε, νυκτὸς ἄγαλμα, Τόσσον ἀφαυρότερος μήνας ὅσον ἔξοχος ἄστρων, and Milton, P.L. iv. 605:  “Hesperus, that led The starry host, rode brightest.”  not that the parts of which it is composed form a harmonious whole; but thanks to the unalloyed and beautiful brightness which meets our eyes.  And further, when God proclaimed the goodness of light, it was not in regard to the charm of the eye but as a provision for future advantage, because at that time there were as yet no eyes to judge of its beauty.  “And God divided the light from the darkness;” Gen. i. 4. that is to say, God gave them natures incapable of mixing, perpetually in opposition to each other, and put between them the widest space and distance.
