Avoid This Common Tattoo Mistake
The most common mistake in Roman numeral tattoos: using IIII instead of IV for 4, or writing dates incorrectly. September 15, 1990 should be IX · XV · MCMXC, not IX · XV · 1990. Always double-check your conversion before it becomes permanent. Tattoo artists are great at lettering but not always at Roman numeral math.

Roman numerals didn't start in Rome. The system evolved from Etruscan tally marks used in central Italy centuries before the Roman Republic. The stroke I for one finger, V for an open hand, X for two hands crossed — these were counting gestures turned into written symbols. Rome adopted and formalized what was already a working system.

It is thought Roman numerals come from hand signals and tally marks. The stroke I represents a finger, the V represents the gap between thumb and fingers for five, and the X represents hands crossed for ten. The L, C, D, and M come from modifications of Greek letters like chi, theta, and phi to represent 50, 100, 500, and 1,000. Over time, these marks changed into the Latin letters people recognize today. There is no 0 in the Roman alphabet, as the concept for the number 0 didn't fully develop until India invented it around 600 CE / 10600 HE.
