Brian Sewell ( ; 15 July 1931 – 19 September 2015) was an English art critic and media personality.
 He wrote for the "London Evening Standard" and was noted for his acerbic view of conceptual art and the Turner Prize. "
The Guardian" described him as "Britain's most famous and controversial art critic", while the "Standard" called him the "nation’s best art critic", and Artnet News called him the United Kingdom's "most famous and controversial art critic".
John Ruskin (8 February 1819 – 20 January 1900) 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.
 Ruskin also penned essays and treatises, poetry and lectures, travel guides and manuals, letters and even a fairy tale.
 The elaborate style that characterised his earliest writing on art was later superseded by a preference for plainer language designed to communicate his ideas more effectively.
 In all of his writing, he emphasised the connections between nature, art and society.
 He also made detailed sketches and paintings of rocks, plants, birds, landscapes, and architectural structures and ornamentation.
Modern Painters (1843–60) is a five-volume work by the eminent Victorian art critic, John Ruskin, begun when he was 24 years old.
 Ruskin argues that recent painters emerging from the tradition of the picturesque are superior in the art of landscape to the old masters.
 The book was primarily written as a defence of the later work of J.M.W. Turner.
 Ruskin used the book to argue that art should devote itself to the accurate documentation of nature.
 In Ruskin's view, Turner had developed from early detailed documentation of nature to a later more profound insight into natural forces and atmospheric effects.
 It was in his 1842 visit to Switzerland that Ruskin collected material used to form the basis of Vol One.

 It was painted by the Pre-Raphaelite artist John Everett Millais (1829–1896) during 1853–54.

The Seven Lamps of Architecture is an extended essay, first published in May 1849 and written by the English art critic and theorist John Ruskin.
 The 'lamps' of the title are Ruskin's principles of architecture, which he later enlarged upon in the three-volume "The Stones of Venice".
 To an extent, they codified some of the contemporary thinking behind the Gothic Revival.
 At the time of its publication A. W. N. Pugin and others had already advanced the ideas of the Revival and it was well under way in practice.
 Ruskin offered little new to the debate, but the book helped to capture and summarise the thoughts of the movement.
 "The Seven Lamps" also proved a great popular success, and received the approval of the ecclesiologists typified by the Cambridge Camden Society, who criticised in their publication "The Ecclesiologist" lapses committed by modern architects in ecclesiastical commissions.
