A retable is a decorative structure placed behind an altar in a church, often featuring religious artwork or sculptures. It serves both a functional and aesthetic purpose, enhancing the visual appeal of the altar and providing a backdrop for worship. Retables can be made from various materials, including wood, stone, or metal, and are commonly found in Christian churches. Historically, retables have been significant in Christian art, showcasing intricate designs and biblical scenes. They often reflect the artistic styles of their time, such as Gothic or Renaissance, and can vary in size and complexity, from simple panels to elaborate multi-tiered constructions.
