About this term
Source: Oxford University Press
Painting applied to an exterior or interior wall surface, especially in a public building or space. During the 19th century a growing sense of national identity in many countries, especially in Europe, and the emergence of new patrons, both private and public, stimulated a revival in didactic and historical mural painting that was closely linked with revivalist movements in architecture. The mural subsequently became a significant art form throughout the modern Western world, where its potential accessibility for a large viewing public and, in some cases, its ability to stimulate public response led to its use in the promotion of a variety of social and political causes. This article discusses the history of this modern development. For discussion of the techniques used in mural painting, and of their development from antiquity to modern times, see Wall painting and Fresco. For discussion of the important role of mural painting in a number of cultures outside the Western world see under the survey article on the appropriate country or civilization.
