Center Flow and Loop Back Dynamics in Pictograms
Image A deserves more attention, (it was on my previous post). Image B shows a similar wings shape as image A, and wings are a barrier symbol.
Image C is showing an example of a handle representing a "side flow" originating from the side of the lower container and it goes up too high, above the brim, (the brim representing the boundary between our-reality and the next-higher-reality, and then the handle does a "loop-back" and comes down. I think the horse head is there as an extra hint.
Image C uses diverging horse heads with their noses or mouths connecting to downward side flow. This is equivalent to my recent post about double-eagle-head symbols. Image E shows this too, a central flow diverging and looping back into side flows.
Image F shows an upward side flow via that cornucopia and a central flow via the horse's body, and then the horse head makes a loop back downward to become a side flow (using the horn symbol).
All this shown above, to show it is plausible that image A's head is a "loop back" symbol of center flow that went above the wings barrier and then is going to loop back down to that side flow dude with his arm up.
I bet you've heard famous 'people who make guesses about symbols', refer to image A in a derogatory way. I only see proper use of symbols in a pictogram.
