John Ruskin was the leading English art critic of the Victorian era, as well as an art patron, draughtsman, watercolourist, a prominent social thinker and philanthropist. He wrote on subjects as varied as geology, architecture, myth, ornithology, literature, education, botany and political economy.
His writing styles and literary forms were equally varied. He penned essays and treatises, poetry and lectures, travel guides and manuals, letters and even a fairy tale. He also made detailed sketches and paintings of rocks, plants, birds, landscapes, and architectural structures and ornamentation.
In 1869, Ruskin became the first Slade Professor of Fine Art at the University of Oxford, where he established the Ruskin School of Drawing.
