Fresco (it. affresco — “fresh”) is a technique for painting walls on lime plaster. Depending on the state of the base, a distinction is made between fresco, when the painting is made on a damp plastered wall, and fresco-secco, when the basis of the image is an already dry wall. Artists use aqueous solutions of pigments that are resistant to alkaline reactions. On the surface of the plaster, moistened with lime water, pigments are absorbed into the top layer, which calcifies after drying and becomes very resistant to moisture.
It is known for sure that during the time of the ancient Aegean culture, frescoes have already become a popular decoration of the house walls. The artists of Ancient Egypt, the ancient Greeks and Romans used painting on lime plaster quite professionally to decorate the interiors of temples, as well as noble palaces, e. g. the famous frescoes found by archaeologists during excavations of ancient Pompeii. The craftsmen used several layers of plaster with different fillers, increasing its drying time thereby and giving themselves the opportunity for comfortable painting on a damp surface. The ancient fresco painting of Byzantium, like the Greek technique, involved at least two layers of lime mortar and the surface carefully smoothed after painting.
The new heyday of fresco painting fell on the Renaissance. By the beginning of the 14th century, Italian artists moved away from the Byzantine art canons and began to develop their own artistic and technical methods. After developing of the composition, the area of the future fresco was divided into sections that could be sketched in one working day — giornatas, which were joined together according to the picture outlines. The image was transferred from the cardboard to the wall in parts. An experienced artist could paint 3 to 4 square meters of walls during a day. Bright green and blue colours could only be applied after the fresco was completely dry: there were no water-soluble pigments of such colours that were resistant to alkali at that time.
Most of the Renaissance artists, including Michelangelo and Raphael, preferred to apply frescoes on wet or slightly damp plaster surfaces. Later, Tiepolo, Tintoretto, Vasari joined their choice. The works created during this period predominantly had religious content (less often, mythological) and adorned the external and internal walls of temples, and the spatial dimensions of the frescoes were amazing.
Today, almost any pictorial interior design is called a fresco - regardless of the technique of its execution. This is primarily due to the extremely rare use of lime plasters for wall covering. Most people associate modern fresco with painted decor; it is rather a design than an artistic solution.
