The Ceiling of the Stanza della Segnatura as a diagram of the Macrocosm with the Four Elements

The 4 Elements in Red refer to Wind's identification of the Mythological and Roman History scenes with the Four Elements. The 4 Elements in Blue refer to the identification of the different disciplines with the Four Elements.

Edgar Wind ("The Four Elements in Raphael's 'Stanza della Segnatura,'" Journal of the Warburg Institute, II, 1937/38, pp.75-79) identifies the scenes in the framework joining the personifications of the disciplines with the four elements. The upper pictures, in grisaille, are drawn from Roman history, while the lower ones, in color, have mythological subject matters. The following table summarizes Wind's arguments.
