Hb9-34	Hb9-35	Hb9-36	Hb9-37	Hb9-38

The mama glyph type could describe a certain kind of black limpet (Chiton magnificus), which is named mama on Easter Island:

The irregularity in shape of the mama in Hb9-38 is presumably to be interpreted as a sign of Mercury, which planet is so close to the dominant Sun that there is no room for stability of character, nor of brilliancy of light. Mercury, which planet 'inhabits' Wednesday (and also the time immediately beyond midsummer) must be a weak person, like a liquid rather than a strong tall tree. The orbit of Mercury is quite irregular which proves it:

In the text of G there is a pair of mama glyphs with an outline like that of the glyph type tao:

tao	Ga4-23	Ga4-24

Evidence in G suggests this outline is intended to describe a canoe, and we can then conclude that the mama pair presumably is meant to be a 'dark double-canoe'.

Counting reveals a correlation with midsummer (corresponding to the 15th day in a month):

15
	Ga4-23	Ga4-24 (108)	Ga4-25	Ga4-26	Ga4-27

108 easily transforms into 180 if we just move the zero forward, and if we count from Gb6-18 it becomes 180 if we add 72:

				68
Gb6-17 (400)	Gb6-18	Gb6-19	Gb6-20		Gb8-30 (472)
0	72
