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 wooden surface provides a sturdy base, enabling artists to achieve fine details and rich colors. 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 exquisite panel works. Over time, this technique evolved, leading to the development of canvas painting, which became more common in the Baroque period.
