Monday, the day of Moon:
Pb10-33	Pb10-34	Pb10-35	Pb10-36	Pb10-37	Pb10-38
growing moon		descending		full moon	black moon
Friday, the day of Venus:
		Venus has two visible faces (phases) - morning and evening 'star' - and in between a 'season' where she cannot be seen.
Pb10-53	Pb10-54

Moon and Venus are 'in hiding' at times. The other planets do not hide in this obvious way.

The two visible phases of Venus, as depicted in Pb10-54, leave an invisible space between them, the form of which - we can imagine - is a rhomb, the same rhomb which is depicted in the mauga glyph.

Mercury is a special case. Mercury is difficult to observe at all times because he (?) is close to Sun and therefore often below the horizon when it is night. But he sometimes is between Sun and Earth like Moon and Venus. In P there is no mauga glyph in Wednesday, but in H there are two.
