A painting or relief sculpture that consists of two parts that are intended to be viewed and appreciated together. The term diptych is derived from an ancient Roman term for a hinged writing tablet common at the time. Small, hinged diptychs became popular during the European middle ages as a way to carry devotional artwork for a little prayer on the road. Today, diptychs are a rarely used but still interesting compositional format. Think three is better than two? Check out the triptych!
