Cook and Wedderburn listed a series of works presented by Ruskin 'on the Walls of the School, or standing on cabinets, etc.' (XXI.300). These were unnumbered, and have been given arbitrary accession numbers, based on their position in Cook and Wedderburn's list, for the purposes of the current catalogue.
Presumably presented by John Ruskin to the Ruskin Drawing School (University of Oxford); first recorded in the Ruskin Drawing School in 1906; transferred from the Ruskin Drawing School to the Ashmolean Museum c.1949
