Aa1-35 Ha6-19 (294) Pa5-64 (299)

A and P, which have the Sun (not egg) in the center are here depicted with two heads, whereas H has only one head.

Why two heads? I imagine it could mean that there are two Suns involved. When the Old Sun is going down in the west it is mirrored in the sea, that makes two.

But that is just an idea. We need to take a 'global view'. Martin P. Nilsson and his "Primitive Time-Reckoning" gives us clues.

After reading him I believe we can be fairly sure that this glyph means ahi-ahi, twice ahi.
