An altarpiece is a work of art, often a painting or sculpture, placed behind or above an altar in a church or chapel. It serves both decorative and devotional purposes, enhancing the spiritual atmosphere of the space. Altarpieces can depict religious scenes, figures, or symbols, and they are typically designed to inspire worship and reflection. Historically, altarpieces have varied in style and complexity, ranging from simple panels to elaborate multi-part structures. Notable examples include the Ghent Altarpiece by Jan van Eyck and the Isenheim Altarpiece by Matthias Grünewald. These works are significant in the study of Renaissance and Baroque art.
