ομβρος ἱερος - ombros hieros - sacred, or holy, rain. This is from line 1428 of Sophocles' Oedipus Tyrannus, Oedipus the King. Hence, in English, hieratic, priestly or of priests; hierarchy, a graded priesthood, etc. I don't know if French ombre, shade, & hence English umbrage, umbrella, etc, is derived from ombros or not. Perhaps someone can tell me?
