Glyph counts between Gallows

[Barbrey]

Barbrey, that's a neat suggestion. Effectively some glyphs would have multiple "registers" and the following glyph "selects" which register is to be read. So rather than 14 glyphs having 14 values, they could have 10 * 4 = 40 values. Some ancient writing systems did have polysemic glyphs, with signs being able to be read as whole words, sounds, or alternative words in different languages. I'm not sure the exact system you suggest is known, but is something which could have been devised at the time.

Thanks Emma May, I've just moved it to its own thread.  I think it's an adaptation of Llull, actually.  That's where i got the idea!
