Renaissance frescoes are large paintings created on wet plaster, allowing the colors to bond with the wall as they dry. This technique was popular during the Renaissance, a cultural movement in Europe from the 14th to the 17th century. Artists like Michelangelo and Raphael used frescoes to depict religious scenes, mythology, and human emotion, showcasing their mastery of perspective and anatomy. These artworks were often found in churches, palaces, and public buildings, serving both decorative and narrative purposes. The vibrant colors and intricate details of Renaissance frescoes aimed to inspire viewers and convey complex stories, making them a significant part of art history.
