COSMOGRAPHIAE

signs, bearing its footprints from the Sun, that is, the middle part of the entire Zodiac, is called "Full" by us, and panselene all-moon/full moon by the Greeks, and it appears in the east at the very moment we see the Sun setting. But after it has promoted its course and has traveled through the third part of the Zodiac, that is, nine signs, then it appears "Waning" and as if diminished, and in this state it is again made dichotomos cut in two.

But having finished its course through the twelve signs, when it arrives at the Sun and is situated next to it, then it is deprived of its light, and by that conjunction it becomes "New" again, and thus it wanders continuously.

And lest you perhaps do not know how it receives light in this revolution, and why such a variety of its light happens, take it this way. The body of the Moon is orbicular and spherical, and also opaque, that is, not at all translucent, and it is kindled only by the approach and aspect of the Sun. But both the form and opacity of its body cause it to be able to be illuminated on all sides by the Sun, insofar as the rays of any light are sent in nothing but a straight line.

For which reason, being situated closest to the Sun, as we taught a little earlier, it has so much darkness that no part of it can be seen by us. For with the Sun standing behind it in a higher place, it happens that it shines on the same side on which the Sun above illuminates it. Indeed
