Robert-Houdin Triple Mystery Clock. Paris: Att. Jean Eugène Robert-Houdin, mid-nineteenth  century. A handsome example of “Triple” Mystery Clock by the famous “father of modern magic,” from the fourth series of Robert-Houdin’s mystery clocks. Time is kept by two arrow-shaped hands attached to a clear glass dial. The dial and circular bezel in turn rest on a tall clear glass tube. This delicate and attractive arrangement itself rests atop four figural mythical beasts, each with a ball held by one foot, which elevate it from the ormolu-decorated platform, providing the third of three mysteries in the working of the timepiece. The spectator is left to guess at how the hands turn and keep time when the dial is made of clear glass, the handsome engraved bezel is supported only by glass tubes, and the tubes themselves are separated from the base. Even so, the clock would keep time and chime at intervals when wound, as if it were an ordinary timepiece. Standing 23” high, including plush-covered brass-inlaid ebonized base. Beveled glass dial finely lettered with the name “Robert-Houdin” and Roman numerals. Strikes the hour and half hour. The movement unsigned. Several elements re-gilded or refinished, and other components restored or entirely replaced. Close examination by an expert horologist recommended. Detailed condition report available on request.
