LXXIII. 1. And after this law I saw another law dealing with the smaller
luminary, which is named the Moon. 2. And her circumference is like the
circumference of the heaven, and her chariot in which she rides is
driven by the wind, and light is given to her in (definite) measure. 3.
And her rising and setting changes every month: and her days are like
the days of the sun, and when her light is uniform (_i. e._ full) it
amounts to the seventh part of the light of the sun. 4. And thus she
rises. And her first phase in the east comes forth on the thirtieth
morning: and on that day she becomes visible, and constitutes for you
the first phase of the moon on the thirtieth day together with the sun
in the portal where the sun rises. 5. And the one half of her goes forth
by a seventh part, and her whole circumference is empty, without light,
with the exception of one-seventh part of it, (and) the fourteenth part
of her light. 6. And when she receives one-seventh part of the half of
her light, her light amounts to one-seventh part and the half thereof.
7. And she sets with the sun, and when the sun rises the moon rises with
him and receives the half of one part of light, and in that night in the
beginning of her morning [in the commencement of the lunar day] the moon
sets with the sun, and is invisible that night with the fourteen parts
and the half of one of them. 8. And she rises on that day with exactly a
seventh part, and comes forth and recedes from the rising of the sun,
and in her remaining days she becomes bright in the (remaining) thirteen
parts.
