A work of art consisting of two panels or sections, typically hinged together so they can be folded like a book. Originally used for religious altarpieces, the format allows for narrative sequences, contrasts, or complementary imagery across the two panels.
From Greek 'diptychos' meaning 'folded in two,' from 'di-' (two) and 'ptychē' (fold). Originally referred to Roman writing tablets with two wax-covered wooden panels that could be folded together.
