Knowra Mural Mural A large-scale artwork painted or applied directly to a wall, ceiling, or other permanent surface. Its composition is shaped by the architecture and setting it occupies.
Fresco : A mural technique in which pigments are applied to wet lime plaster and become part of the wall as it dries. This durable method makes the wall itself the painting’s support.
Sistine Chapel ceiling : Michelangelo’s painted ceiling in the Vatican’s Sistine Chapel, completed between 1508 and 1512. Its biblical scenes demonstrate how a vast ceiling can become a unified painted environment.
Cave painting : Images made on the walls or ceilings of caves, often using mineral pigments or charcoal. Some of the earliest known wall images establish a deep history for art on fixed surfaces.
Public art : Art created for public spaces or intended to be accessible to a broad public. Murals are a prominent form of art placed directly in shared environments.
Mural conservation : The documentation, treatment, and care of murals to slow deterioration while preserving their material and historical value. Conservators must address fragile paint, architectural damage, and changing environmental conditions.
Secco : A painting technique that applies pigment to dry plaster, usually with a binding medium. It offers a wall-painting alternative to applying pigment on wet plaster.
The Last Supper : Leonardo da Vinci’s mural painting of Jesus and his disciples in Milan’s Santa Maria delle Grazie. Its deteriorating experimental technique shows the risks of departing from traditional fresco.
Ancient Egyptian art : The visual arts of ancient Egypt, including tomb paintings, reliefs, sculpture, and decorated objects. Egyptian tomb walls preserve extensive examples of images designed for architectural settings.
Street art : Visual art created in public spaces, often outside conventional galleries and institutions. Many contemporary murals overlap with street art in their sites and audiences.
Fresco secco deterioration : The loss or damage of paint applied to dry plaster, often caused by weak adhesion or environmental stress. This vulnerability can threaten murals made with dry-plaster techniques.
