Diary of John Ruskin

The Diary of John Ruskin - 1861, 1862, 1863, also known as ‘MS12’ or the ‘Rock Book’, was in use between 1859 and 1863. In addition to accounts of his visits to Ireland and the Continent, the notebook contains Ruskin’s translations of Bernhard Studer’s Geologie der Schweiz (Bern: Stämpflische Verlagshandlung, 1851–53), historical notes and geological diagrams.

The image shows the watercolour key that Ruskin developed for the geological diagrams in the following pages. The key does not follow a standard, but his own taxonomical system. Ruskin’s categories enable him to record the detail specific to his own observation of landscape: for example, four different forms of ‘molasse’ (deposits that form in front of mountains), marked in blue.

Ruskin kept diary notebooks throughout his life. The Ruskin Whitehouse Collection includes 29 volumes, dating from 1835 to 1888. The pages contain notes, sketches, diagrams, drawings and paintings; and offer an insight into his wide-ranging interests, from art and architecture, to technology and ecology. Although portions of Ruskin's diary notebooks have been transcribed, many of the pages in the notebooks have never been published.

MS12 is a quarto-sized account book. Bound in vellum, it measures 20.4 x 17 cm and contains 262 pages. The first part of the notebook includes pages 1 to 141, containing historical and geological notes (pages 1-141). The second part of the notebook works backwards from the last page, and includes Ruskin's diary entries for the years 1861 to 1863 (pages 262-145).

Extracts from MS12 appear in the second volume of Joan Evans and John Howard Whitehouse's The Diaries of John Ruskin, 3 vols (Oxford: Clarendon Press, 1956–1959).
