Technique and condition
Turner traced this preparatory drawing of a Tuscan column in perspective to make the guiding outlines of Diagrams 40 and 41 (Tate D17059, D17060; Turner Bequest 89, 90) for his lectures as Professor of Perspective at the Royal Academy. A tracing from the drawing (D40003) on the back of the unrelated Diagram 36 (Tate D17052; Turner Bequest CXCV 82) has been obscured by a mount.
See Tate D40004.
