Etymology: In Latin, "lumen" meant light, and "luminare" was a thing that gave it off: a lamp, a window, or any source of shining. Its most consequential use came in the Latin Bible, where the Vulgate applied the plural "luminaria" to the two great lights God set in the sky in Genesis, the sun and moon. A word for an ordinary lamp thus came to name the heavenly bodies. English mostly took this family of words through Old French, producing "luminary," which kept the sense of a celestial body and later came to mean a person who guides or inspires others. "Luminare" itself survives as a rarer learned borrowing from Latin, used for a light source in the literal sense.
