In Federico de Montefeltro's cipher ledger book (You are not allowed to view links. Register or Login to view., 1440-1469), several cipher alphabets based on simple substitution are recorded.
Take a look at the first one, intended to be used by Sigismondo Pandolfo Malatesta, looks like this:
[attachment=19040]
If you take a closer look at the glyph for the letter "x", you might see something familiar:
[attachment=19047]
In both cases, the glyph seems to be composed of a "left part" that looks like a 4, and a right part, that looks like a loop.
[attachment=19049]
Looking some other ciphers in the ledger, one might notice that it is possible to "construct" such a glyph, looking like an EVA "t", by combining the following two glyphs:
[attachment=19048]
The result is an EVA "t"-looking glyph.
[attachment=19043]
Could this be the way that the EVA glyph "t" was "assembled"? If yes, then it might encode not one, but two letters in one glyph.
