Frescoes are a type of mural painting created on freshly laid wet plaster. As the plaster dries, the pigments bond with it, making the artwork an integral part of the wall. This technique has been used since ancient times, notably in ancient Rome and during the Renaissance. Artists often used frescoes to depict religious scenes, historical events, or daily life. Famous examples include the ceiling of the Sistine Chapel painted by Michelangelo and the walls of Pompeii. Frescoes are valued for their vibrant colors and durability, as they can last for centuries when properly maintained.
