An architectural style is a classification of buildings based on a set of characteristics and features, including overall appearance, arrangement of the components, method of construction, building materials used, form, size, structural design, and regional character.
The Architect's Dream by Thomas Cole (1840) shows a vision of buildings in the historical styles of the Western tradition, including ancient Egyptian, ancient Greek, ancient Roman, and Gothic.
In the visual arts, style is a "... distinctive manner which permits the grouping of works into related categories" or "... any distinctive, and therefore recognizable, way in which an act is performed or an artifact made or ought to be performed and made". Style refers to the visual appearance of a work of art that relates to other works with similar aesthetic roots, by the same artist, or from the same period, training, location, "school", art movement or archaeological culture: "The notion of style has long been historian's principal mode of classifying works of art".
