Panel painting is a technique where artists create images on flat wooden panels, often using oil or tempera paints. This method was popular during the Renaissance and allowed for detailed and vibrant artwork. The smooth surface of the panel provides a stable base, enabling fine brushwork and intricate designs. Historically, panel paintings were often used for altarpieces in churches and private homes. Artists like Jan van Eyck and Sandro Botticelli are well-known for their contributions to this art form. Over time, panel painting evolved, leading to the development of canvas painting, which became more common in the Baroque period.
