Определение и Значение "diptych"

What is a "diptych"?

A diptych is a type of artwork, often a painting or engraving, created on two separate panels of wood or other materials that are intended to be viewed together. These panels are typically connected by hinges, allowing them to open and close like a book. Each panel can stand alone as an individual piece, but when placed side by side, they form a unified image or theme. Diptychs are often used to tell a story, show contrasting or complementary images, or create a more complex visual experience. Historically, diptychs were commonly used as decorative pieces in churches, where they could be opened to display religious scenes and closed for protection.
