Greek numerals

[eve_prime]

J is now playing the early access version of Hades II, the sequel to our beloved Hades, and as a result, I learned something new. The main antagonist is Chronos, the Titan who rules over time, and our character, Melin oë, the daughter of Hades and Persephone, has met him several times. The art for Chronos includes the Roman numerals from one (I) to twelve (XII), but that struck me as wrong. Rome comes later than the era of Greek mythology. Why not Greek numerals? (Unless the anachronism of using the Roman ones is some sort of deliberate pun, I guess.)

For whatever reason, I had never given thought to Greek numerals before, but thanks to Wikipedia, I now know that they worked basically like Roman numerals, but using Greek letters, of course. Per Wikipedia:
Ι = 1, Γ = 5, Δ = 10, ΓΔ = 50, Η = 100, ΓΗ = 500, Χ = 1000, ΓΧ = 5000, Μ = 10000 and ΓΜ = 50000

I'd never thought about Greek numerals before, so that was interesting. Of course Greek letters are used a lot in maths, but with different and modern meanings.

Yes, exactly - I'd never thought about it before, but when I saw the Roman ones, I thought, wait, this can't be right...
