The best assumption i also have that they are a crossing between a zodiac symbol and a seagull.

If you look at my user image, you see a squirrel. The right upper glyph also resembles a squirrel from the side.
However, nowadays i believe the left glyphs represent a (capital or magical) letter of some sort. But, what exactly i do not know.
