teachers, where he instituted a May Queen festival that endures today. (It was also replicated in the 19th century at the Cork High School for Girls.) Ruskin also bestowed books and gemstones upon Somerville College, one of Oxford's first two women's colleges, which he visited regularly, and was similarly generous to other educational institutions for women. Modern Painters III and IV Both volumes III and IV of Modern Painters were published in 1856. In MP III Ruskin argued that all great art is "the expression of the spirits of great men". Only the morally and spiritually healthy are capable of admiring the noble and the beautiful, and transforming them into great art by imaginatively penetrating their essence. MP IV presents the geology of the Alps in terms of landscape painting, and their moral and spiritual influence on those living nearby. The contrasting final chapters, "The Mountain Glory" and "The Mountain Gloom" provide an early example of Ruskin's social analysis, highlighting the poverty of the peasants living in the lower Alps. Public lecturer In addition to leading more formal teaching classes, from the 1850s Ruskin became an increasingly popular public lecturer. His first public lectures were given in Edinburgh, in November 1853, on architecture and painting. His lectures at the Art Treasures Exhibition, Manchester in 1857, were collected as The Political Economy of Art and later under Keats's phrase, A Joy For Ever. In these lectures, Ruskin spoke about how to acquire art, and how to use it, arguing that England had forgotten that true wealth is virtue, and that art is an index of a nation's well-being. Individuals have a responsibility to consume wisely, stimulating beneficent demand. The increasingly critical tone and political nature of Ruskin's interventions outraged his father and the "Manchester School" of economists, as represented by a hostile review in the Manchester Examiner and Times. As the Ruskin scholar Helen Gill Viljoen noted, Ruskin was increasingly critical of his father, especially in letters written by Ruskin directly to him, many of them still unpublished. Ruskin gave the inaugural address at the Cambridge School of Art in 1858, an institution from which the modern-day Anglia Ruskin University has grown. In The Two Paths (1859), five lectures given in London, Manchester, Bradford and Tunbridge Wells, Ruskin argued that a 'vital law' underpins art and architecture, drawing on the labour theory of value.
