What is a Roman numerals clock?
Most modern or vintage watches and clocks rely on a mix of additive notation and subtractive notation (where the 4 is IIII and the 9 is IX). This way, the dial features the following numerals: I, II, III, IIII, V, VI, VII, VIII, IX, X, XI, XII.
Why is the 4 in Roman numeral clocks wrong?
The reason isn’t all that far fetched. Using four I’s instead of IV for the “four” is due to the casting process of the numerals. Since some numerals were cast out of metal, or carved out of wood or bone, you need 20 I’s, 4 V’s, and 4 X’s, even numbers of each, if you use four I’s for “four”.
Why is the 6 upside down on a Roman numeral clock?
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.
