The use of astronomical symbols for the Sun and Moon dates to antiquity. The forms of the symbols that appear in the original papyrus texts of Greek horoscopes are a circle with one ray for the Sun and a crescent for the Moon.

Crest and trough in a wave. A Crest point on a wave is the highest point of the wave. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point of the wave.
Venus reaches its greatest magnitude of about −4.5 when it is an intermediate crescent shape at the point in its orbit, when it is 68 million km away from the Earth, at which point the illuminated part of its disk reaches its greatest angular area as seen from the Earth (a combination of its closeness and the fact that it is 28% illuminated).
During the crescent phase, the darker side of the Moon reflects indirect sunlight, reflected from Earth, while the other side reflects direct sunlight. An 80 mm shot of a crescent Moon with a 10-second exposure, revealing earthshine. The green ghost image was caused by a UV filter on the lens.
