Diagram 55 is a perspective construction of a Tuscan entablature. In his discussion of the architectural orders in Lecture 4 as Professor Perspective at the Royal Academy, Turner compares it together with Diagram 56 (Tate D17079; Turner Bequest CXCV 109) to Diagrams 53 and 54 (Tate D17073, D17074; Turner Bequest CXCV 103, 104) which are both examples of the Corinthian order.1 Indications of transfer process on the back indicate that he traced the drawing to make the guiding lines of Diagram 56 (Tate D17079, see also D17077).
