"(Gesenius would here translate 'fire-hearth of God,' after Arab. arr; elsewhere in O.T. the same word occurs as a man's name, and appellation of Jerusalem, where it is taken as = 'lion of God.') Ariel in T. Heywood and Milton is the name of an angel, in Shakespeare of 'an Ayrie spirit'; in Astron. of one of the satellites of Uranus." [OED]
"It was a tacit conviction of the learned during the Middle Ages that no such thing as an insoluble question existed. There might be matters that presented serious difficulties, but if you could lay them before the right man -- some Arab in Spain, for instance, omniscient by reason of studies into the details of which it was better not to inquire -- he would give you a conclusive answer. The real trouble was only to find your man." [Gertrude Bell, "The Desert and the Sown," 1907]"Peple žat cleped hem self Saracenys, as žogh žey were i-come of Sarra" [John of Trevisa, transl. Higdon's Polychronicon, 1387] The name Greeks and Romans gave to the nomads of the Syrian and Arabian deserts. Specific sense of "Middle Eastern Muslim" is from the Crusades.
