Etymology: "Patinae" is simply the plural of "patina," so the story belongs to that word. The original sense was literal: Latin "patina" meant a shallow dish or pan, borrowed from Ancient Greek "patánē" with the same meaning. The surface film sense came later, when Italian used "patina" for the greenish crust that forms on old bronze and copper, and English took the word from Italian. The Greek and Latin word is a doublet of "paten," the shallow plate used for the bread at Communion, and of "patine," an older English form that shares the same dish-shaped ancestor. Scholars are unsure whether the Greek word goes back to a Proto-Indo-European root meaning "to spread" or comes from an earlier, non-Indo-European language of the Greek region, so the ultimate origin of the dish idea remains open.
