1690s, present participle adjective from revolve (v.). Revolving door attested from 1856 in industrial processes, 1896 in buildings.

late 14c., “to change direction, bend around, turn (the eyes) back,” from Old French revolver and directly from Latin revolvere “roll back, unroll, unwind; happen again, return; go over, repeat,” from re- “back, again” (see re-) + volvere “to roll” (see volvox). In 15c., “to turn over (in the mind or heart), meditate.” Meaning “travel around a central point” first recorded 1660s (earlier “cause to travel in an orbit around a central point,” mid-15c.).
