A triptych by Giovanni del Biondo, 1370
A triptych (from the Greek tri- "three" + ptychē "fold") is a painting which is divided into three sections, or three carved panels which are hinged together to form a complete artwork.
Triptychs were most common with Renaissance painters and sculptors, especially those who presented religious themes, like Hans Memling and Hieronymus Bosch.
Altarpieces in churches and cathedrals, both in Europe and elsewhere, were often in triptych-form. One such cathedral is Llandaff Cathedral. The Cathedral of Our Lady in Antwerp, Belgium contains two examples by Rubens.
A triptych is also a type of branching on a printed circuit board as well as a music festival in Scotland.
Triptych is also a computer game by Chronic Logic.
