The magical substance known as ‘starmoon

A magical substance made by the Elves from mithril, that could only be seen by the light of the Moon and stars, and even then remained hidden until a magical word was said. Gandalf translated its name as 'starmoon', but 'moon-sparkle' would perhaps be a more literal rendering. The designs on the West-gate of Moria were made from this substance.



II 1697 is the first mention in history of the Doors of Durin that were marked with ithildin, so the substance must have been in existence at this date. Of course this is the absolute latest possible date for its creation; it presumably dated back farther this, perhaps by centuries or even millennia. The fact that it incorporated mithril, however, implies that it was probably first devised in Eregion, and therefore no earlier than about II 750.


It is not clear how widely ithildin was used. Gandalf was familiar enough with the substance to remember the specific spell that brought it to life, which rather implies that he had come across it before, though he may have gained the same information through research rather than experience. The substance contained mithril, which could be found only in Khazad-dûm, but in earlier days the Dwarves would trade far afield. Thus it was conceivable for Elves outside the particular region around Khazad-dûm to have worked with the substance.


Gandalf's translation of ithildin as 'starmoon' is close, but not completely literal. The name comes from ithil, 'Moon' and din, 'glint', 'sparkle', also used of small faint stars. So the name would literally be 'moon-sheen', or poetically 'moonstar'.
