Fresco (plural<em> frescos</em> or <em>frescoes</em>) is a technique of mural painting executed upon freshly laid ("wet") lime plaster. Water is used as the vehicle for the dry-powder pigment to merge with the plaster, and with the setting of the plaster, the painting becomes an integral part of the wall. The word fresco (Italian: <em>affresco</em>) is derived from the Italian adjective fresco meaning "fresh", and may thus be contrasted with fresco-secco or secco mural painting techniques, which are applied to dried plaster, to supplement painting in fresco. The fresco technique has been employed since antiquity and is closely associated with <u>Italian Renaissance painting</u>.

Fresco. Fresco (Italian: “fresh”) is the traditional medium for painting directly onto a wall or ceiling. It is the oldest known painting medium, surviving in the prehistoric cave mural decorations and perfected in 16th-century Italy in the buon' fresco method.
