This isn't THE clock, just A clock. But they ALL have the "wrong" 4 for roman numerals. After a spot of googling it turns out the Romans didn't really use "IV", we just sort of invented it later on, presumably for symmetry with IX. But there you go, never noticed it before.
Anyway, I thought that was semi-interesting (look out for my new series S.I.) and weird because after years of looking at those sorts of clocks I never noticed it was totally at odds with everything I'd been taught. Anyone else got a similar observation of wrongness?*
