Catalogue entry

Made by Turner for his lectures as Professor of Perspective at the Royal Academy, Diagram 72 depicting an Ionic capital is based on the right-hand part of an illustration from A Compleat Treatise on Perspective in Theory and Practice on the True Principles of Dr Brook Taylor (1775, pl.XXII, fig.104) by the elder Thomas Malton (1726–1801). It is associated by Maurice Davies with a large group of diagrams illustrating the production of shadows; see note to Diagram 60 (Tate D17085; Turner Bequest CXCV 115). Turner also refers to a diagram numbered ‘72’ when discussing Diagram 52 (Tate D17070; Turner Bequest CXCV 100), a perspective construction of an Ionic capital based on the left portion of Malton’s plate.1 For the preliminary drawing from which Turner traced this diagram, see Tate D17098 (Turner Bequest CXCV 127).
The same capital is represented in perspective, and then with entablature in Diagrams 73 and 73+ (Tate D17097, D17100; Turner Bequest CXCV 126, 129).
