Kenneth Clark in the context of "Bernard Berenson"

Joseph Mallord William Turner RA (23 April 1775 – 19 December 1851), known in his time as William Turner, was an English Romantic painter, printmaker and watercolourist. He is known for his expressive colouring, imaginative landscapes and turbulent, often violent marine paintings. His artistic style developed over his lifetime, moving away from Romanticism—bypassing the following rising style of Realism—and, instead, with his later works being a significant precursor of and presaging the later Impressionist and Abstract Art movements that arose in the decades after his death. He left behind more than 550 oil paintings, 2,000 watercolours, and 30,000 works on paper. He was championed by the leading English art critic John Ruskin from 1840, and is today regarded as having elevated landscape painting to an eminence rivalling history painting. In 1969 art historian Kenneth Clark wrote of Turner: "He was a genius of the first order—far the greatest painter that England has ever produced..."

Turner was born in Maiden Lane, Covent Garden, London, to a modest lower-middle-class family and retained his lower-class accent, while assiduously avoiding the trappings of success and fame. A child prodigy, Turner studied at the Royal Academy of Arts from 1789, enrolling when he was 14, and exhibited his first work there at 15. During this period, he also served as an architectural draftsman. He earned a steady income from commissions and sales, which he often only begrudgingly accepted owing to his troubled and contrary nature. He opened his own gallery in 1804 and became professor of perspective at the academy in 1807, where he lectured until 1828. He travelled around Europe from 1802, typically returning with voluminous sketchbooks.

The Return of the Prodigal Son (Dutch: De terugkeer van de verloren zoon) is an oil painting by Rembrandt, part of the collection of the Hermitage Museum in St. Petersburg. It is among the Dutch master's final works, likely completed within two years of his death in 1669. Depicting the moment of the prodigal son's return to his father in the Biblical parable, it is a renowned work described by art historian Kenneth Clark as "a picture which those who have seen the original in St. Petersburg may be forgiven for claiming as the greatest picture ever painted".

In the painting, the son has returned home in a wretched state from travels in which he has wasted his inheritance and fallen into poverty and despair. He kneels before his father in repentance, wishing for forgiveness and the position of a servant in his father's household, having realized that even his father's servants had a better station in life than he. His father receives him with a tender gesture and welcomes him as his own son. His hands seem to suggest mothering and fathering at once; the left appears larger and more masculine, set on the son's shoulder, while the right is softer and more receptive in gesture. Standing at the right is the prodigal son's older brother, who crosses his hands in judgment; in the parable he objects to the father's compassion for the sinful son:

Roger Eliot Fry (14 December 1866 – 9 September 1934) was an English painter and critic, and a member of the Bloomsbury Group. Establishing his reputation as a scholar of the Old Masters, he became an advocate of more recent developments in French painting, to which he gave the name Post-Impressionism. He was an early figure to raise public awareness of modern art in Britain, and he emphasised the formal properties of paintings over the "associated ideas" conjured in the viewer by their representational content. He was described by the art historian Kenneth Clark as "incomparably the greatest influence on taste since Ruskin ... In so far as taste can be changed by one man, it was changed by Roger Fry". The taste Fry influenced was primarily that of the Anglophone world, and his success lay largely in alerting an educated public to a compelling version of recent artistic developments of the Parisian avant-garde.

The Flagellation of Christ (1459–1460) is a painting by Piero della Francesca in the Galleria Nazionale delle Marche in Urbino, Italy. Called by one writer an "enigmatic little painting," the composition is complex and unusual, and its iconography has been the subject of widely differing theories. Kenneth Clark called The Flagellation "the greatest small painting in the world".

The Third of May 1808 in Madrid (commonly known as The Third of May 1808) and also known, in Spanish, as El tres de mayo de 1808 en Madrid or Los fusilamientos de la montaña del Príncipe Pío, or Los fusilamientos del tres de mayo, is a painting completed in 1814 by the Spanish painter Francisco Goya, now in the Museo del Prado, Madrid. In the work, Goya sought to commemorate Spanish resistance to Napoleon's armies during the occupation of Madrid in 1808 at the start of the Peninsular War. Along with its companion piece of the same size, The Second of May 1808 (or The Charge of the Mamelukes), it was commissioned by the provisional government of Spain at Goya's own suggestion shortly after the ousting of the French occupation and the restoration of King Ferdinand VII.

The painting's content, presentation, and emotional force secure its status as a ground-breaking, archetypal image of the horrors of war. Although it draws on many sources from both high and popular art, The Third of May marks a clear break from convention. By diverging from the traditions of Christian art and traditional depictions of war, it has no distinct precedent, and is acknowledged as one of the first paintings of the modern era. According to the art historian Kenneth Clark, it is "the first great picture which can be called revolutionary in every sense of the word, in style, in subject, and in intention".

The office of the Surveyor of the King's/Queen's Pictures, in the Royal Collection Department of the Royal Household of the Sovereign of the United Kingdom, is responsible for the care and maintenance of the royal collection of pictures owned by the Sovereign in an official capacity – as distinct from those owned privately and displayed at Sandringham House and Balmoral Castle and elsewhere. The office has only been full-time since 1972. It now operates in a professional capacity with a staff of a dozen people.

Although the office dates from 1625, during the reign of Charles I (a noted art connoisseur), there has always been someone responsible for pictures in the Royal Household. Notable recent office-holders have included Sir Lionel Cust (1901–1927), Sir Kenneth Clark (1934–1944), Professor Anthony Blunt (1945–1972), one of the Cambridge Five Soviet spies, and Sir Oliver Millar (1972–1988). The current surveyor is Anna Reynolds, who was appointed in December 2023. She is the first woman to hold the position.

The marble Kritios Boy or Kritian Boy belongs to the Early Classical period of ancient Greek sculpture. It is the first statue from classical antiquity known to use contrapposto; Kenneth Clark called it "the first beautiful nude in art" The Kritios Boy is thus named because it is attributed, on slender evidence, to Kritios, who worked together with Nesiotes (sculptors of Harmodius and Aristogeiton) or their school, from around 480 BC. As currently mounted, the statue is considerably smaller than life-size at 117 cm (3 ft 10 ins), including the supports that replace the missing feet.
