A revolving stage is a mechanically controlled platform within a theatre that can be rotated in order to speed up the changing of a scene within a show. A fully revolving set was an innovation constructed by the hydraulics engineer Tommaso Francini for an elaborately produced pageant, Le ballet de la délivrance de Renaud, which was presented for Marie de Medici in January 1617 at the Palais du Louvre and noted with admiration by contemporaries. Such a stage is also commonly referred to as a turntable.
