Hi Chris Aldrich. Interesting approach.
Yes, there are many hidden, arcane
and cryptic notions in many artifacts of medieval Art.

By the way since I’m Greek (born/raised/living),
we just spell Simonides as Σιμωνίδης o Κείος.
“Σιμωνίδης ὁ Κεῖος” is not a name written in Ancient Greek but a form of Modern Greek using the old Polytonic system (which was abandoned in late 1970’s.)
(basic polytons= oksia/οξεία, psily/ψιλή, perispomeni/περισπωμένη and some more)

Ask any Classical scholar about this, and he’ll say that in Ancient Greece they would write his name in inscriptions as:
"ΣΙΜΟΝΙΔΗΣΟΚΕΙΟΣ " because they neither used spaces nor small letters.

So, it was all capitalised. This may seem familiar from the 3 inscriptions in the Rosetta Stone. (Hieroglyphic/ Demotic Egyptian/ Capital Greek). The last bottom section of Rosetta Stone is capitalised Classical Ancient Greek.

Latin, Hebrew, Ancient Greek, Old Germanic(or Gothic) and Old English languages , are often very important in order to decipher some cryptic medieval European messages.
Those were probably the 5 main Linguae Francae (“main languages”) in the Ancient and Medieval Western World.
