(30) And in periods of seven days the moon undergoes its changes. In the first week she becomes half moon; in the second, full moon; and in the third, in her wane, again half moon; and in the fourth she disappears. Further, as Seleucus the mathematician lays down, she has seven phases. First, from being invisible she becomes crescent-shaped, then half moon, then gibbous and full; and in her wane again gibbous, and in like manner half moon and crescent-shaped.

(2) And it came to pass then, on the fifteenth day of the moon in the month Tybi, which is the day on which the moon is full, on that day then, when the sun had come forth in his going, that there came forth behind him a great light-power shining most exceedingly, and there was no measure to the light conjoined with it. For it came out of the Light of lights, and it came out of the last mystery, which is the four-and-twentieth mystery, from within without,--those which are in the orders of the second space of the First Mystery. And that light-power came down over Jesus and surrounded him entirely, while he was seated removed from his disciples, and he had shone most exceedingly, and there was no measure for the light which was on him.

(104) Morning and Evening are and reach only up from the Earth to the Moon, and take their Original from the Light of the Sun, and this makes Evening and Morning, as also the outward Day, and the outward dark Night, as every one knows.

(5) Now when this was done, the Deep became clear, and with the hidden or concealed Heaven the Light was separated from the Darkness, and the Globe of the Earth in the great Wheel of Nature was rolled or turned once about; and accordingly there passed the Time of one Revolution, or of one Day, which contains twenty-four Hours. [The Diurnal Motion of the Earth 24 Hours.]

(4) The reappearance of the moon, and the creation of the month

(1) It came to pass then, when that light-power had come down over Jesus, that it gradually surrounded him entirely. Then Jesus ascended or soared into the height, shining most exceedingly in an immeasurable light. And the disciples gazed after him and none of them spake, until he had reached unto heaven; but they all kept in deep silence. This then came to pass on the fifteenth day of the moon, on the day on which it is full in the month Tybi.

(138) For the Goddess bringeth forth the Vast Sun, and the lucent Moon.
