This is the second volume of the catalogue raisonne of the work of the American painter John Singer Sargent (1856-1925). It comprises over 150 formal portraits and portrait sketches in oil and watercolour that he painted between 1889 and 1900. The catalogued works have been grouped into chronological sections, each with its own introduction to set the particular group in context. In addition, an overall introduction places Sargent in the context of European portraiture of the past and of his own time. Each work is documented in depth: entries include traditional data about the painting or watercolour; details of the work's provenance, exhibition history, and bibliography; a short biography of the sitter; a discussion of the circumstances in which the work was created; and a critical discussion of its subject matter, style, and significance in Sargent's career. With very few exceptions, all the works are reproduced in colour. There is also an illustrated inventory of Sargent's studio props and accessories and a cross-referenced checklist of the portraits in which they appear.
