For the record, IIII as opposed to IV dates from uncial lettering and has a religious significance. As most people know, the Chief Honcho of the Roman Gods was Jupiter – but notice that we write that with an initial “Ju-” which were not classic Roman letters, and that the rest of the word is “-piter,” a variant on “pater” meaning “Father.” The actual name in uncials was written with an I for the modern J and a V for the modern U – producing IVPITER, of which the first part was the “name” and the second the father appellation.
Pious Roman pagans avoided writing IV as a separate entity for 4, since it was the name of the Father God – and Christians when they became prevalent avoided it because it was acknowledging a pagan god. Therefore the custom of using IIII on clocks, etc., in lieu of the IV of classic subtractive Roman numerals arose out of religious scruples.
Note, though, that this did not apply to XIV, XXIV, LXIV, etc., where the letters constituting the divine name were simply a part of the number. Only as a standalone IV was it deemed to represent Jupiter’s name and therefore avoided. (To work up a parallel, a devout Og-ite if there were such a person would not find “We slogged through the bog with our tracking dog in search of the lost clog” (presumably Coldfire’s ;)) as referencing their deity; the words merely contain the divine name as letters.)
