A closed fist was used as a sign of 'nothing as yet counted':

... The practice of turning down the fingers, contrary to our practice, deserves notice, as perhaps explaining why sometimes savages are reported to be unable to count above four. The European holds up one finger, which he counts, the native counts those that are down and says 'four'. Two fingers held up, the native counting those that are down, calls 'three'; and so on until the white man, holding up five fingers, gives the native none turned down to count. The native is nunplussed, and the enquirer reports that savages can not count above four ... (Dr. Codrington in Melanesian Languages, p. 222, note 1, as related in Churchill 2)

 

This fact suggests a pair of fists will correspond to 5 + 5 = 10:

... Whare-patari, who is credited with introducing the year of twelve months into New Zealand, had a staff with twelve notches on it. He went on a visit to some people called Rua-roa (Long pit) who were famous round about for their extensive knowledge. They inquired of Whare how many months the year had according to his reckoning. He showed them the staff with its twelve notches, one for each month. They replied: 'We are in error since we have but ten months. Are we wrong in lifting our crop of kumara (sweet potato) in the eighth month?' Whare-patari answered: 'You are wrong. Leave them until the tenth month. Know you not that there are two odd feathers in a bird's tail? Likewise there are two odd months in the year.'

Finally I would like to suggest a correspondence beetween our glyph and the place where according to ancient Egypt the Canoe of the Sun was bound to reach the end of the night side journey:

 

Here there was a kind of Net for catching the prow of the ship, and the pair of star signs attatched by a pair of strings to one of the corners of this net ought to correspond to the pair of fists attatched by a pair of limbs to the waterfilled canoe:

 

 

In Egypt the direction 'up' towards the mountain region from where the Nile originated was not in the north (as the rest of the world though), instead it was in the south. Therefore the nighttime strings had to be changed into daytime limbs.

 

But the orientation must correspond to that in Egypt, i.e. to the vertical - the orientation of the force of gravitation pushing the water downwards in spring.
