Reliefs are three-dimensional representations of a subject, often created on a flat surface. They can be classified into different types, such as bas-relief, where the figures project slightly from the background, and high relief, where the figures stand out more prominently. Reliefs are commonly made from materials like stone, wood, or metal and are used in various forms of art, including sculptures and architectural decorations. Reliefs have been used throughout history to convey stories, commemorate events, or depict important figures. They can be found in ancient structures, such as Egyptian temples and Roman monuments, as well as in modern art. The technique allows for intricate details while maintaining a connection to the surface it is carved from.
