Modern Painters, Volume 1

Anger at criticism in the press gives John Ruskin's discussion of landscape painting its argumentative edge. In this first volume, he defends Turner while setting out broader standards for judging art. He asks that comparisons rest on demonstrable truth rather than the reputation of a painter or school. His preface also draws a careful distinction between challenging an artist's relative standing and denying the value of that artist's work.

The argument becomes concrete in his account of how the eye sees distance. A simple experiment with a square and a circle shows how forms grow indistinct without disappearing. Leaves, windows and masonry help explain why a painted landscape cannot give every object equal clarity. These passages bring aesthetics into contact with practical observation. Readers interested in painting, visual perception or the language of art criticism can follow Ruskin as he tests pictures against the appearances of the natural world.
