Portraiture's roots are likely found in prehistoric times, although few of these works survive today. In the art of the ancient civilizations of the Fertile Crescent especially in Egypt, depictions of rulers and gods abound. However, most of these were done in a highly stylized fashion, and most in profile, usually on stone, metal, clay, plaster, or crystal. Egyptian portraiture placed relatively little emphasis on likeness, at least until the period of Akhenaten in the 14th century BC. Portrait painting of notables in China probably goes back to over 1000 BC, though none survive from that age. Existing Chinese portraits go back to about 1000 AD
From literary evidence we know that ancient Greek painting included portraiture, often highly accurate if the praises of writers are to be believed, but no painted examples remain. Sculpted heads of rulers and famous personalities like Socrates survive in some quantity, and like the individualized busts of Hellenistic rulers on coins, show that Greek portraiture could achieve a good likeness, and subjects were depicted with relatively little flattery - Socrates' portraits show why he had a reputation for being ugly. The successors of Alexander the Great began the practice of adding his head (as a deified figure) to their coins, and were soon using their own.
Roman portraiture adopted traditions of portraiture from both the Etruscans and Greeks, and developed a very strong tradition, linked to their religious use of ancestor portraits, as well as Roman politics. Again, the few painted survivals, in the Fayum portraits, Tomb of Aline and the Severan Tondo, all from Egypt under Roman rule, are clearly provincial productions that reflect Greek rather than Roman styles, but we have a wealth of sculpted heads, including many individualized portraits from middle-class tombs, and thousands of types of coin portraits.
Much the largest group of painted portraits are the funeral paintings that survived in the dry climate of Egypt's Fayum district (see illustration, below), dating from the 2nd to 4th century AD. These are almost the only paintings of the Roman period that have survived, aside from frescos, though it is known from the writings of Pliny the Elder that portrait painting was well established in Greek times, and practiced by both men and women artists. In his times, Pliny complained of the declining state of Roman portrait art, "The painting of portraits which used to transmit through the ages the accurate likenesses of people, has entirely gone out…Indolence has destroyed the arts." These full-face portraits from Roman Egypt are fortunate exceptions. They present a somewhat realistic sense of proportion and individual detail (though the eyes are generally over-sized and the artistic skill varies considerably from artist to artist). The Fayum portraits were painted on wood or ivory in wax and resin colors (encaustic) or with tempera, and inserted into the mummy wrapping, to remain with the body through eternity.
While free-standing portrait painting diminished in Rome, the art of the portrait flourished in Roman sculptures, where sitters demanded realism, even if unflattering. During the 4th century, the sculpted portrait dominated, with a retreat in favor of an idealized symbol of what that person looked like. (Compare the portraits of Roman Emperors Constantine and Theodosius) In the Late Antique period the interest in an individual likeness declined considerably, and most portraits in late Roman coins and consular diptychs are hardly individualized at all, although at the same time early Christian art was evolving fairly standardized images for the depiction of Jesus and the other major figures in Christian art, such as John the Baptist, and Saint Peter.
Most early medieval portraits were donor portraits, initially mostly of popes in Roman mosaics, and illuminated manuscripts, an example being a self-portrait by the writer, mystic, scientist, illuminator, and musician Hildegard of Bingen (1152). As with contemporary coins, there was little attempt at a likeness. Stone tomb monuments spread in the Romanesque period. Between 1350-1400, secular figures began to reappear in frescos and panel paintings, such as in Master Theodoric's Charles IV receiving fealty, and portraits once again became clear likenesses. Around the end of the century, the first oil portraits of contemporary individuals, painted on small wood panels, emerged in Burgundy and France, first as profiles, then in other views. The Wilton Diptych of ca. 1400 is one of two surviving panel portraits of Richard II of England, the earliest English King for whom we have contemporary examples. Leading Early Netherlands masters of the portrait included Jan van Eyck, Robert Campin and Rogier van der Weyden. Portraits of donors began to be shown as present, or participate in the main sacred scenes shown, and in more private court images subjects even appeared as significant figures such as the Virgin Mary.
The Renaissance marked a turning point in the history of portraiture. Partly out of interest in the natural world and partly out of interest in the classical cultures of ancient Greece and Rome, portraits—both painted and sculpted—were given an important role in Renaissance society and valued as objects, and as depictions of earthly success and status. Painting in general reached a new level of balance, harmony, and insight, and the greatest artists (Leonardo, Michelangelo, and Raphael) were considered "geniuses", rising far above the tradesman status to valued servants of the court and the church.
Many innovations in the various forms of portraiture evolved during this fertile period. The tradition of the portrait miniature began, which remained popular until the age of photography, developing out of the skills of painters of the miniatures in illuminated mauscripts. Profile portraits, inspired by ancient medallions, were particularly popular in Italy between 1450 and 1500. Medals, with their two–sided images, also inspired a short-lived vogue for two-sided paintings early in the Renaissance. Classical sculpture, such as the Apollo Belvedere, also influenced the choice of poses utilized by Renaissance portraitists, poses that have continued in usage through the centuries.
Northern European artists led the way in realistic portraits of secular subjects. The greater realism and detail of the Northern artists during the 15th century was due in part to the finer brush strokes and effects possible with oil colours, while the Italian and Spanish painters were still using tempera. Among the earliest painters to develop oil technique was Jan van Eyck. Oil colors can produce more texture and grades of thickness, and can be layered more effectively, with the addition of increasingly thick layers one over another (known by painters as ‘fat over lean’). Also, oil colors dry more slowly, allowing the artist to make changes readily, such as altering facial details. Antonello da Messina was one of the first Italians to take advantage of oil. Trained in Belgium, he settled in Venice around 1475, and was a major influence on Giovanni Bellini and the Northern Italian school. During the 16th century, oil as a medium spread in popularity throughout Europe, allowing for more sumptuous renderings of clothing and jewelry. Also affecting the quality of the images, was the switch from wood to canvas, starting in Italy in the early part of the 16th century and spreading to Northern Europe over the next century. Canvas resists cracking better than wood, holds pigments better, and needs less preparation―but it was initially much scarcer than wood.
Early on, the Northern Europeans abandoned the profile, and started producing portraits of realistic volume and perspective. In the Netherlands, Jan van Eyck was a leading portraitist. The Arnolfini Marriage (1434, National Gallery, London) is a landmark of Western art, an early example of a full-length couple portrait, superbly painted in rich colors and exquisite detail. But equally important, it showcases the newly developed technique of oil painting pioneered by van Eyck, which revolutionized art, and spread throughout Europe.
Leading German portrait artists including Lucas Cranach, Albrecht Durer, and Hans Holbein the Younger who all mastered oil painting technique. Cranach was one of the first artists to paint life-sized full-length commissions, a tradition popular from then on. At that time, England had no portrait painters of the first rank, and artists like Holbein were in demand by English patrons. His painting of Sir Thomas More (1527), his first important patron in England, has nearly the realism of a photograph. Holbein made his great success painting the royal family, including Henry VIII. Dürer was an outstanding draftsman and one of the first major artists to make a sequence of self-portraits, including a full-face painting. He also placed his self-portrait figure (as an onlooker) in several of his religious paintings. Dürer began making self-portraits at the age of thirteen. Later, Rembrandt would amplify that tradition.
In Italy, Masaccio led the way in modernizing the fresco by adopting more realistic perspective. Filippo Lippi paved the way in developing sharper contours and sinuous lines and his pupil Raphael extended realism in Italy to a much higher level in the following decades with his monumental wall paintings. During this time, the betrothal portrait became popular, a particular specialty of Lorenzo Lotto. During the early Renaissance, portrait paintings were generally small and sometimes covered with protective lids, hinged or sliding.
During the Renaissance, the Florentine and Milanese nobility, in particular, wanted more realistic representations of themselves. The challenge of creating convincing full and three-quarter views stimulated experimentation and innovation. Sandro Botticelli, Piero della Francesca, Domenico Ghirlandaio, Lorenzo di Credi, and Leonardo da Vinci and other artists expanded their technique accordingly, adding portraiture to traditional religious and classical subjects. Leonardo and Pisanello were among the first Italian artists to add allegorical symbols to their secular portraits.
One of best-known portraits in the Western world is Leonardo da Vinci's painting titled Mona Lisa, named for Lisa del Giocondo a member of the Gherardini family of Florence and Tuscany and the wife of wealthy Florentine silk merchant Francesco del Giocondo. The famous "Mona Lisa smile" is an excellent example of applying subtle asymmetry to a face. In his notebooks, Leonardo advises on the qualities of light in portrait painting:
"A very high degree of grace in the light and shadow is added to the faces of those who sit in the doorways of rooms that are dark, where the eyes of the observer see the shadowed part of the face obscured by the shadows of the room, and see the lighted part of the face with the greater brilliance which the air gives it. Through this increase in the shadows and the lights, the face is given greater relief."
Leonardo was a student of Verrocchio. After becoming a member of the Guild of Painters, he began to accept independent commissions. Owing to his wide-ranging interests and in accordance with his scientific mind, his output of drawings and preliminary studies is immense though his finished artistic output is relatively small. His other memorable portraits included those of noblewomen Ginevra de’ Benci and Cecilia Gallerani.
Raphael's surviving commission portraits are far more numerous than those of Leonardo, and they display a greater variety of poses, lighting, and technique. Rather than producing revolutionary innovations, Raphael great accomplishment was strengthening and refining the evolving currents of Renaissance art. He was particularly expert in the group portrait. His masterpiece the School of Athens is one of the foremost group frescoes, containing likenesses of Leonardo, Michelangelo, Bramante, and Raphael himself, in the guise of ancient philosophers. It was not the first group portrait of artists. Decades earlier, paolo Uccello had painted a group portrait including Giotto, Donatello, Antonio Manetti, and Brunelleschi. As he rose in prominence, Raphael became a favorite portraitist of the popes. While many Renaissance artists eagerly accepted portrait commissions, a few artists refused them, most notably Raphael's rival Michelangelo, who instead undertook the huge commissions of the Sistine Chapel.
In Venice around 1500, Gentile Bellini and Giovanni Bellini dominated portrait painting. They received the highest commissions from the leading officials of the state. Bellini's portrait of Doge Loredan is considered to be one of the finest portraits of the Renaissance and ably demonstrates the artist's mastery of the newly arrived techniques of oil painting. Bellini is also one of the first artists in Europe to sign their work, though he rarely dated them. Later in the 16th century, Titian assumed much the same role, particularly by expanding the variety of poses and sittings of his royal subjects. Titian was perhaps the first great child portraitist. After Titian succumbed to the plague, Tintoretto and Veronese became leading Venetian artists, helping the transition to Italian Mannerism. The Mannerists contributed many exceptional portraits that emphasized material richness and elegantly complex poses, as in the works of Agnolo Bronzino and Jacopo da Pontormo. Bronzino made his fame portraying the Medici family. His daring portrait of Cosimo L de'Medici, shows the austere ruler in armor with a wary eye gazed to his extreme right, in sharp contrast to most royal paintings which show their sitters as benign sovereigns. El Greco, who trained in Venice for twelve years, went in a more extreme direction after his arrival in Spain, emphasizing his "inner vision" of the sitter to the point of diminishing the reality of physical appearance. One of the best portraitists of 16th-century Italy was Sofonisba Anquissola from Cremona, who infused her individual and group portraits with new levels of complexity.
Court portraiture in France began when Flemish artist Jean Clouet painted his opulent likeness of Francis I of France around 1525. King Francis was a great patron of artists and an avaricious art collector who invited Leonardo da Vinci to live in France during his later years. The Mona Lisa stayed in France after Leonardo died there.
Baroque and Rococo
During the Baroque and Rococo periods (17th and 18th centuries, respectively), portraits became even more important records of status and position. In a society dominated increasingly by secular leaders in powerful courts, images of opulently attired figures were a means to affirm the authority of important individuals. Flemish painters Sir Anthony van Dyck and Peter Paul Rubens excelled at this type of portraiture, while Jan Vermeer produced portraits mostly of the middle class, at work and play indoors. Rubens’ portrait of himself and his first wife (1609) in their wedding attire is a virtuoso example of the couple portrait. Rubens fame extended beyond his art—he was a courtier, diplomat, art collector, and successful businessman. His studio was one of the most extensive of that time, employing specialists in still-life, landscape, animal and genre scenes, in addition to portraiture. Van Dyck trained there for two years. Charles I of England first employed Rubens, then imported van Dyck as his court painter, knighting him and bestowing on him courtly status. Van Dyck not only adapted Rubens’ production methods and business skills, but also his elegant manners and appearance. As was recorded, "He always went magnificently dress’d, had a numerous and gallant equipage, and kept so noble a table in his apartment, that few princes were not more visited, or better serv’d." In France, Hyacinthe Riqaud dominated in much the same way, as a remarkable chronicler of royalty, painting the portraits of five French kings.
One of the innovations of Renaissance art was the improved rendering of facial expressions to accompany different emotions. In particular, Dutch painter Rembrandt explored the many expressions of the human face, especially as one of the premier self-portraitists (of which he painted over 60 in his lifetime). This interest in the human face also fostered the creation of the first caricatures, credited to the Carracci Academy, run by painters of the Carracci family in the late 16th century in Bologna, Italy (see Annibale Carracci).
Group portraits were produced in great numbers during the Baroque period, particularly in the Netherlands. Unlike in the rest of Europe, Dutch artists received no commissions from the Calvinist Church which had forbidden such images or from the aristocracy which was virtually non-existent. Instead, commissions came from civic and businesses associations. Dutch painter Frans Hals used fluid brush strokes of vivid color to enliven his group portraits, including those of the civil guards to which he belonged. Rembrandt benefitted greatly from such commissions and from the general appreciation of art by bourgeois clients, who supported portraiture as well as still-life and landscapes painting. In addition, the first significant art and dealer markets flourished in Holland at that time.
With plenty of demand, Rembrandt was able to experiment with unconventional composition and technique, such as chiaroscuro. He demonstrated these innovations, pioneered by Italian masters such as Caravaggio, most notably in his famous Night Watch (1642). The Anatomy Lesson of Dr. Tulp (1632) is another fine example of Rembrandt's mastery of the group painting, in which he bathes the corpse in bright light to draw attention to the center of the painting while the clothing and background merge into black, making the faces of the surgeon and the students standout. It is also the first painting that Rembrandt signed with his full name.
In Spain, Diego Velazquez painted Las Meninas (1656), one of the most famous and enigmatic group portraits of all time. It memorializes the artist and the children of the Spanish royal family, and apparently the sitters are the royal couple who are seen only as reflections in a mirror. Starting out as primarily a genre painter, Velazquez quickly rose to prominence as the court painter of Philip IV, excelling in the art of portraiture, particularly in extending the complexity of group portraits.
Rococo artists, who were particularly interested in rich and intricate ornamentation, were masters of the refined portrait. Their attention to the details of dress and texture increased the efficacy of portraits as testaments to worldly wealth, as evidenced by Francois Boucher's famous portraits of Madame de Pompadour attired in billowing silk gowns.
The first major native portrait painters of the British school were English painters Thomas Gainsborough and Sir Joshua Reynolds, who also specialized in clothing their subjects in an eye-catching manner. Gainsborough's Blue Boy is one of the most famous and recognized portraits of all time, painted with very long brushes and thin oil color to achieve the shimmering effect of the blue costume. Gainsborough was also noted for his elaborate background settings for his subjects.
The two British artists had opposite opinions on using assistants. Reynolds employing them regularly (sometimes doing only 20 percent of the painting himself) while Gainsborough rarely did. Sometimes a client would extract a pledge from the artist, as did Sir Richard Newdegate from portraitist Peter Lely (van Dyck's successor in England), who promised that the portrait would be "from the Beginning to ye end drawne with my owne hands." Unlike the exactitude employed by the Flemish masters, Reynolds summed up his approach to portraiture by stating that, "the grace, and, we may add, the likeness, consists more in taking the general air, than in observing the exact similitude of every feature." Also prominent in England was William Hogarth, who dared to buck conventional methods by introducing touches of humor in his portraits. His "Self-portrait with Pug" is clearly more a humorous take on his pet than a self-indulgent painting.
In the 18th century, female painters gained new importance, particularly in the field of portraiture. Notable female artists include French painter Elisabeth Viqee-Lebrun, Italian pastel artist Rosalba Carriera, and Swiss artist Angelica Kauffmann. Also during that century, before the invention of photography, miniature portraits―painted with incredible precision and often encased in gold or enameled lockets―were highly-valued.
In the United States, Johm Singleton Copley, schooled in the refined British manner, became the leading painter of full-size and miniature portraits, with his hyper-realistic pictures of Samuel Adams and Paul Revere especially well-regarded. Copley is also notable for his efforts to merge portraiture with the academically more revered art of history painting, which he attempted with his group portraits of famous military men. Equally famous was Gilbert Stuart who painted over 1,000 portraits and was especially known for his presidential portraiture. Stuart painted over 100 replicas of George Washington alone. Stuart worked quickly and employed softer, less detailed brush strokes than Copley to capture the essence of his subjects. Sometimes he would make several versions for a client, allowing the sitter to pick their favorite. Noted for his rosy cheek tones, Stuart wrote, "flesh is like no other substance under heaven. It has all the gaiety of the silk-mercer's shop without its gaudiness of gloss, and all the softness of old mahogany, without its sadness." Other prominent American portraitists of the colonial era were John Smibert, Thomas Sully, Ralph Earl, John Trumbull, Benjamin West, Robert Feke, James Peale, Charles Willson Peale, and Rembrandt Peale.
In the late 18th century and early 19th century, neoclassical artists continued the tradition of depicting subjects in the latest fashions, which for women by then, meant diaphanous gowns derived from ancient Greek and Roman clothing styles. The artists used directed light to define texture and the simple roundness of faces and limbs. French painters Jacques-Louis David and Jean-Auguste-Dominique Ingres demonstrated virtuosity in this draftsman-like technique as well as a keen eye for character. Ingres, a student of David, is notable for his portraits in which a mirror is painted behind the subject to simulate a rear view of the subject. His portrait of Napoleon on his imperial throne is a tour de force of regal portraiture.
Romantic artists who worked during the first half of the 19th century painted portraits of inspiring leaders, beautiful women, and agitated subjects, using lively brush strokes and dramatic, sometimes moody, lighting. French artists Eugene Delacroix and Theodore Gericault painted particularly fine portraits of this type, especially dashing horsemen. Also noteworthy is Géricault's series of portraits of mental patients (1822–1824). Spanish painter Francisco de Goya painted some of the most searching and provocative images of the period, including La maja desnuda (c. 1797-1800), as well as famous court portraits of Charles IV.
The realist artists of the 19th century, such as Gustave Courbet, created objective portraits depicting lower and middle class people. Demonstrating his romanticism, Courbet painted several self-portraits showing himself in varying moods and expressions. Other French realists include Honore Daumier who produced many caricatures of his contemporaries. Henri de Toulouse-Lautrec chronicled some of the famous performers of the theater, including Jane Avril, capturing them in motion. French painter Edouard Manet, was an important transitional artist whose work hovers between realism and impressionism. He was a portraitist of outstanding insight and technique, with his painting of Stephane Mallarne being a good example of his transitional style. His contemporary Edgar Degas was primarily a realist and his painting Portrait of the Bellelli Family is an insightful rendering of an unhappy family and one of his finest portraits.
In America, Thomas Eakins reigned as the premier portrait painter, taking realism to a new level of frankness, especially with his two portraits of surgeons at work, as well as those of athletes and musicians in action. In many portraits, such as "Portrait of Mrs. Edith Mahon", Eakins boldly conveys the unflattering emotions of sorrow and melancholy.
The Realists mostly gave way to the Impressionists by the 1870s. Partly due to their meager incomes, many of the Impressionists relied on family and friends to model for them, and they painted intimate groups and single figures in either outdoors or in light-filled interiors. Noted for their shimmering surfaces and rich dabs of paint, Impressionist portraits are often disarmingly intimate and appealing. French painters Claude Monet and Pierre-Auguste Renoir created some of the most popular images of individual sitters and groups. American artist Mary Cassatt, who trained and worked in France, is popular even today for her engaging paintings of mothers and children, as is Renoir. Paul Gauquin and Vincent van Gogh, both Post-Impressionists, painted revealing portraits of people they knew, swirling in color but not necessarily flattering. They are equally, if not more so, celebrated for their powerful self-portraits.
John Singer Sargent also spanned the change of century, but he rejected overt Impressionism and Post-Impressionism. He was the most successful portrait painter of his era, using a mostly realistic technique often effused with the brilliant use of color. He was equally apt at individual and group portraits, particularly of upper-class families. Sargent was born in Florence, Italy to American parents. He studied in Italy and Germany, and in Paris. Sargent is considered to be the last major exponent of the British portrait tradition beginning with van Dyck. Another prominent American portraitist who trained abroad was William Merritt Chase. American society painter Cecilia Beaux, called the "female Sargent", was born of a French father, studied abroad and gained success back home, sticking with traditional methods. Another portraitist compared to Sargent for his lush technique was Italian-born Parisian artist Giovanni Boldini, a friend of Degas and Whistler.
American-born Internationalist James Abbott McNeil Whistler was well-connected with European artists and also painted some exceptional portraits, most famously his "Arrangement in Grey and Black, The Artist's Mother" (1871), also known as "Whistler's Mother". Even with his portraits, as with his tonal landscapes, Whistler wanted his viewers to focus on the harmonic arrangement of form and color in his paintings. Whistler used a subdued palette to create his intended effects, stressing color balance and soft tones. As he stated, "as music is the poetry of sound, so is painting the poetry of sight, and the subject-matter has nothing to do with the harmony of sound or of color." Form and color were also central to Cezannes portraits, while even more extreme color and brush stroke technique dominate the portraits by Andre Derain, and Henri Matisse.
The development of photography in the 19th century had a significant effect on portraiture, supplanting the earlier camera obscura which had also been previously used as an aid in painting. Many modernists flocked to the photography studios to have their portraits made, including Baudelaire who, though he proclaimed photography an "enemy of art", found himself attracted to photography's frankness and power. By providing a cheap alternative, photography supplanted much of the lowest level of portrait painting. Some realist artists, such as Thomas Eakins and Edgar Degas, were enthusiastic about camera photography and found it to be a useful aid to composition. From the Impressionists forward, portrait painters found a myriad number of ways to reinterpret the portrait to compete effectively with photography. Sargent and Whistler were among those stimulated to expand their technique to create effects that the camera could not capture.
Other early 20th-century artists also expanded the repertoire of portraiture in new directions. Fauvist artist Henri Matisse produced powerful portraits using non-naturalistic, even garish, colors for skin tones. Cezanne's relied on highly simplified forms in his portraits, avoiding detail while emphasizing color juxtapositions. Austrian Gustav Klimt's unique style applied Byzantine motifs and gold paint to his memorable portraits. His pupil Oskar Kokoschka was an important portraitist of the Viennese upper class. Prolific Spanish artist Pablo Picasso painted many portraits, including several cubist renderings of his mistresses, in which the likeness of the subject is grossly distorted to achieve an emotional statement well beyond the bounds of normal caricature.
Expressionist painters provided some of the most haunting and compelling psychological studies ever produced. German artists such as Otto Dix and Max Beckmann produced notable examples of expressionist portraiture. Beckmann was a prolific self-portraitist, producing at least twenty-seven. Amedeo Modiqliani painted many portraits in his elongated style which depreciated the "inner person" in favor of strict studies of form and color. To help achieve this, he de-emphasized the normally expressive eyes and eyebrows to the point of blackened slits and simple arches.
British art was represented by the Vorticists, who painted some notable portraits in the early part of the 20th century. The Dada painter Francis Picabia executed numerous portraits in his unique fashion. Additionally, Tamara de Lempicka's portraits successfully captured the Art Deco era with her streamlined curves, rich colors and sharp angles. In America, Robert Henri and George Bellows were fine portraitists of the 1920s and 1930s of the American realist school. Max Ernst produced an example of a modern collegial portrait with his 1922 painting "All Friends Together".
A significant contribution to the development of portrait painting of 1930-2000 was made by Russian artists, mainly working in the traditions of realist and figurative painting. Among them should be called Isaak Brodsky, Nikolai Fechin, Abram Arkhipov, Lev Russov, Nikolai Baskakov, Alexander Samokhvalov, Piotr Buchkin, Engels Kozlov, Oleg Lomakin, Boris Korneev, Piotr Belousov, and others.
Portrait production in Europe (excluding Russia) and the Americas generally declined in the 1940s and 1950s, a result of the increasing interest in abstraction and nonfigurative art. One exception, however, was Andrew Wyeth who developed into the leading American realist portrait painter. With Wyeth, realism, though overt, is secondary to the tonal qualities and mood of his paintings. This is aptly demonstrated with his landmark series of paintings known as the "Helga" pictures, the largest group of portraits of a single person by any major artist (247 studies of his neighbor Helga Testorf, clothed and nude, in varying surroundings, painted during the period 1971–1985).
By the 1960s and 1970s, there was a revival of portraiture. English artists such as Lucian Freud (grandson of Sigmund Freud) and Francis Bacon have produced powerful paintings. Bacon's portraits are notable for their nightmarish quality. In May 2008, Freud's 1995 portrait Benefits Supervisor Sleeping was sold by auction by Christies in New York City for $33.6 million, setting a world record for sale value of a painting by a living artist. Many contemporary American artists, such as Andy Warhol, Alex Katz and Chuck Close, have made the human face a focal point of their work. Warhol's painting of Marilyn Monroe is an iconic example. Close's specialty was huge, hyper-realistic wall-sized "head" portraits based on photographic images. Jamie Wyeth continues in the realist tradition of his father Andrew, producing famous portraits whose subjects range from Presidents to pigs.
