Type of object with several panels, usually an altarpiece, although it may also fulfil other functions. The polyptych normally consists of a central panel with an even number of side-panels, which are sometimes hinged to fold. Although in principle every object with two panels or more may be called a polyptych, the word is normally used as a general term for anything larger than a triptych. As with diptychs and triptychs, the size and material can vary.
