Ruskin's revised catalogue of 300 works for the instruction of undergraduates and his notes on the use of particular examples.
Two broad, shallow dishes are shown one above the other, seen from above. The upper, seen more from the side, is yellow inside and orange outside. The lower, seen more from above, is coloured yellow and decorated with thin radiating stripes of red and blue combined. Beneath the watercolour and bodycolour can be seen two networks of ruled graphite lines, each organised aound two horizontals and two sets of orthogonals receding to points beyond the upper left and right corners respectively, which define the perspective construction of the each dish. A crudely-drawn rectangle is indicated in graphite, defining the area to be made visible through the mount, approximately 16 x 20 cm.
According to Taylor, this perspective drawing, its companion in the frame, and those in frame 215 of the Educational Series, were made by Ruskin during a period of intense work on the Teaching Collection in the spring of 1871. They do not appear in the "Catalogue of Examples" (1870), but are listed in the first catalogue of the Educational Series (1871) in Case IX, 'Illustrations of the Connection between Decorative and Realistic Design', as nos 2 and 2 A. They remained in the same positions in the 1874, although renumbered 214 and 215 respectively, but are not mentioned in the 1878 reorganisation of the series.
Taylor relates the drawings in frame 214 to problem XIV, 'To draw a Truncated Circular Cone', in Ruskin's "Elements of Perspective" (XV.287-289), although they do not seem to have been intended as direct illustrations of that particular text.
Presented by John Ruskin to the Ruskin Drawing School (University of Oxford), 1875; transferred from the Ruskin Drawing School to the Ashmolean Museum, c.1949.
