END OF SHADOWY GLOOM.
The rising of the dawn always anticipates the rising of the sun. And before the shining brightness of the sun’s rays shed light upon the earth, dawn brings an end to the darkness of the night. Little by little, once the blindness of darkness has been vanquished, a certain shape and light is poured out on everything. Though the earth had lain in disarray, as if under the substance of darkness, once the dawn arrives, different things are distinguished by the variety of their appearances. In other words, although all things had been blind, now the eyes of all are restored. For night removes the eyes from the world, if you will, but dawn gives them back again.
