This perspective construction of a Corinthian entablature is partly based on diagrams from John Joshua Kirby’s The Perspective of Architecture (1761, pl.XXVII, fig.B and pl.XXIX, fig.B). Turner does not seem to have developed the pen and wash drawing into a full-scale diagram for his lectures as Professor of Perspective at the Royal Academy. However, Maurice Davies relates the subject to Turner’s discussion of the problems of circles in standard perspective, where the artist refers to the Corinthian capital and particularly to the crushed appearance of the entablature.
