Amethystos
(Ancient Greek) - IPA(key)
Amethystos (/ɑː.mɛ.ˈθuːs.toʊs/) is an unusually dark moon approximately 70,000 kilometers away from Eos. During the day, its sky glows with fuchsia and a light purple, to which it owes its namesake. Since its atmosphere is held closely to the surface, ground-level fog quickly obscures the relatively flat terrain, with notable exception in mountainous regions which often extend above the atmospheric layer.
Nomenclature
Amethyste or Amethystos is supposedly a nymph in Greek mythology who is turned into a precious stone by the goddess Diana in order to avoid a worse fate at the hands of the god Dionysus, thus explaining the origin of the semi-precious stone amethyst. Although this tale has circulated a lot in various sites and books, no ancient source attests to it, and its origin is much later than either ancient Greece or Rome.
