pavilion: [13] Pavilion got its name because some anonymous ancient Roman was reminded by a tent, with its two ‘wings’ spread out from a central crosspiece, of a ‘butterfly’. Latin for ‘butterfly’ was pāpiliō (a word of unknown origin), which hence came to be used for ‘tent’. English acquired it via Old French pavillon.
