Wow I’d never seen that before. Also just curious on the reasoning, why would they use IIII for symmetry but not do anything about VI, VII and so on? Is it more to do with the width of the number when written down maybe?
VI would be IIIIII which is severely over-wide. The balance is really against VIII and XII, you don’t want one leg of that triangle to have a limp and IIII makes IV just a bid wider and chunkier to provide that balance. “Symmetry” was probably a poor choice of word this isn’t a mathematical thing but perceptual, those three points being equal visual weight evoke an equilateral triangle standing on its side which says “yep this won’t tip over, ever”, because, well, things shaped such don’t.
The IVPPITER explanation definitely also makes sense but it doesn’t explain why people continued to do it after standardisation on IV in arithmetic and the fall of Roman paganism.
When Roman numerals were in use by the Roman Empire, the name of the Romans’ supreme deity, Jupiter, was spelled as IVPPITER in Latin. There was a feeling that using the start of Jupiter’s name on a clock dial, and it being upside down where it fell, would be disrespectful to the deity, so IIII was introduced instead.

I was taught that dividing the numbers naturally into thirds:
Visually looks more “balanced” than having an extra V

That’s really cool info
