> In the middle ages in Europe, IIII was generally used, not IV, to express the Roman numeral 4 until around the 17th century. This definitely stuck around much longer. I've seen plenty of wall clocks from the late 19th and early 20th century which also had the IIII instead of IV - and always wondered why some clocks from that time used IV and some used IIII (maybe it was just a retro-fashion at that time though, don't know).
