The yellow/blue cube in f102v2

[Scarecrow]

You are right Koen about the symbolism, that began after the 14th, but that was not the thing I was referring to with my quote.
The thought I had was about the Arabic and Greek translations, and thus also their glyphs and symbols. 

Now if someone had access to both language books, and decided to invent a new series of glyphs to combine/streamline two in one, the Arabic and the Greek glyphs, and maybe even position-dependent glyphs/characters as Arabic has; same characters can have different glyphs depending on the position in the vord, on the line.
