Thomas Cole: Eden to Empire @ the National Gallery

This is a fabulously enjoyable exhibition on numerous levels. It contains 58 works, the majority on loan from North American collections, focusing on a score of masterpieces by American landscape painter Thomas Cole – making this a once-in-a-lifetime chance to see so many of his works together in one place.

It also brings together some enormous paintings by Claude, Constable, Turner and John Martin to show how Cole studied and learned from them.

And, quite apart from the visually stunning impact of many of these huge works, it is rich in thought-provoking issues and ideas.

Four rooms and seven chapters

Thomas Cole is famous in the U.S. as the greatest American landscape artist of his generation, more or less founding the young republic’s tradition of landscape painting.

In fact he was British, born in Bolton, Lancashire in 1801 to a middle class family in reduced circumstances. So reduced that young Thomas was sent out to work while still school age, among other jobs working as an assistant to an engraver.

The story of his life, achievement and influence is told in the four rooms of the National Gallery’s ground Floor Galleries, which have been divided into seven sections or ‘chapters’. There’s also a handy timeline of his life on one wall, to give a sense of the flow and development of his career before he was struck down tragically young, dying aged 47 in 1848.

Chapter 1. Industrial England

Cole was born in Bolton near Manchester as the industrial revolution reached its first flood of development.

The first section includes a vivid depiction of the impact of this new coal and iron technology in Philippe Jacques de Loutherbourg’s painting Coalbrookdale by Night, painted in 1801 the year of Cole’s birth. Note the enormous abandoned cogs and crankshafts at the bottom left and their resemblance to the ruined columns in paintings of Roman and Greek ruins i.e. the way older aesthetic forms lingered on in the new world.

Not only was the physical landscape being devastated, but so were the people too, the old cottage-based artisan economy eroded by mass production in the new manufactories where people were reduced to ‘hands’, working 12 hours a day, seven days a week, to serve the machines.

This prompted a backlash. Nearby hangs a contemporary lampoon of a Luddite, one of the gangs of workers who smashed up the machinery in a bid to halt ‘progress’ and to keep work human.

When his father’s business failed, Cole, a sensitive well-educated teenager, was forced to take work engraving printing blocks in a local cotton mill. He had, quite literally, hands-on experience of the way industrial ‘progress’ was making work mechanical and alienating.

In 1817 the family moved to Liverpool where Cole got a job working in an engraver’s shop where he would have seen prints by the leading artists of the day.

Chapter 2. American Wilderness

When he was 17 Cole’s parents decided to emigrate. His family sailed to America and settled in Philadelphia. Cole was now determined to become a painter, borrowing all the textbooks he could find and taking lessons from an itinerant artist. In 1825 he moved to New York City and that summer took a steamboat trip up the Hudson river into the Catskill Mountains.

He made numerous sketches of this picturesque landscape, rich in hills, valleys, small rivers, abundant wildlife and forests stretching as far as the eye could see. Already it was a tourist destination for New Yorkers but Cole removed all human traces from his sketches and especially from the finished paintings he worked up from them, depicting the landscape as a virgin wilderness.

Although there are a few tiny sailboats on the river in the far distance of this painting you’d be forgiven for not seeing them. What you are meant to see is the wild and storm-battered trees and the outcrop of rock, highlighted in the foreground and set against the ominous dark shape of the mountain (Round Top) rising behind it.

In these paintings Cole was seeking, in his own words, ‘a higher style of landscape’. He was influenced by the prints he’d seen of the magnificent sprawling light effects achieved by J.M.W. Turner and the grandiose melodramatic effects of ‘end of the world’ John Martin. What makes this exhibition even more visually stunning than it would have been is the inclusion of some wildly dramatic works by Turner and Martin of the sort which inspired young Cole.

A classic example of Cole’s literary or melodramatic embellishment of landscape is this fantastical scene from James Fenimore Cooper’s classic novel of the wilderness north of New York, Last of the Mohicans, published just the year before, in 1826.

The humans are obviously dwarfed by the setting, an improbably fantastical circular ledge of rock on the right of the picture, allowing the left half to reveal a ‘sublime’ receding vista of successive rugged mountains, lakes, and more mountains. The very human passions of Cooper’s novel have been translated into an image of almost cosmic significance.

These paintings attracted buyers, and word of mouth led Cole to be taken up by some very wealthy patrons. It was one of these patrons, Luman Reed, who paid for Cole to return to Europe and undertake a tour of Italy in order to improve his technique and his life drawing.

Chapter 3. London: Imperial Metropolis

So at the age of 28 Cole returned to Europe, stopping in London, where he visited the newly opened ‘National Gallery’ to study Old Masters. Here he actually met Constable and Turner. He was invited for a personal tour of the latter’s studio, where he admired the remarkable painting, Snow Storm: Hannibal and his Army Crossing the Alps.

You can see how this kind of thing played to Cole’s interest in depicting absolutely massive natural landscapes, enormous cosmic or geographical motifs which dwarf their puny human characters.

But like everyone else who met him, Cole was disappointed by the contradiction between the sublimity of Turner’s paintings and the man himself, who was dirty, smelly, abrupt and inarticulate, having the appearance and manners, as Cole put it, of ‘the mate of a coasting vessel’.

At the Royal Academy Cole exhibited some of his own landscapes, such as the striking Distant View of Niagara Falls, which he actually completed in London from sketches taken at the scene, and which he deliberately painted with a view to wowing the London public. He was disappointed when they didn’t make much impact.

Chapter 4. The Grand Tour

Cole travelled quickly through Paris, which held no interest for him, and on to Florence, where he spent eight months getting to know the town’s close-knit artistic community, painting the city and going out into the surrounding countryside to paint landscapes and especially all and any remains of the once-great Roman Empire.

In 1832 he moved on to Rome itself, studying and sketching all the famous sites and also venturing out into the surrounding countryside, much loved by the French painted Claude Lorraine whose work he had admired in London.

This part of the exhibition displays figure studies Cole did in Italy, as well as oil paintings of Florence and of picturesque Roman ruins embedded in the tranquil Italian countryside.

Chapter 5. The Course of Empire

Cole returned to the States in 1832 and became a citizen in 1834. It was now, after all this training and preparation, that he began work on the ambitious cycle of five massive paintings designed to portray the rise and fall of an imaginary civilisation which he was to call The Course of Empire.

Visually, the ‘civilisation’ – i.e. the buildings, clothes and trappings of all the inhabitants – are based on ancient Rome, with its vast classical buildings, all pillars, porticoes and domes. But the landscape, the natural setting of the rise and fall, are recognisably the America of Cole’s Catskill paintings.

In this, the first of the sequence, a ‘savage’ dressed in a loincloth in the middle foreground on the left is chasing a deer he has wounded with an arrow, at the bottom and slightly to the right of middle. In the distance on the right is a circle of Indian teepees with a fire burning. Looming up out of the John Martin-style, over-arching clouds, is a sloping mountain topped by a distinctive boulder, which appears in all five paintings.

The sequence as a whole can be quickly taken in on Wikipedia.

The five paintings are:

  • The Savage State
  • The Arcadian or Pastoral State
  • The Consummation of Empire
  • Destruction
  • Desolation

As you can see, the paintings combine epic scale and deep perspective with a beguiling attention to minute detail. For example, in the second painting, look for the old man tracing geometric shapes in the sand with a stick, the first tremors of the ‘science’ which will give rise to ‘industry’.

The Consummation of Empire is in some ways the most visually pleasing. It’s physically the biggest of the five, but I think a lot of its success is due to the importance of light in bringing an unexpected sense of air and spaciousness to what ought to be a ridiculously crowded and crammed composition.

It adds to your appreciation to learn that the five paintings are conceived of taking place at different times of day: Savage at dawn, Arcadia in mid-morning, Consummation in the full light of a Mediterranean noon, Destruction in the late afternoon, and Desolation at moonrise.

A whole room is devoted to these five enormous paintings (with a handful of works from Italy on other walls so you can see where ideas of perspective, and especially of classical buildings and plant-covered ruins came from). It is a dazzling array of visionary genius.

Chapter 6. Cole’s Manifesto

Andrew Jackson was the seventh president of the United States, serving from 1829 to 1837, that’s to say at exactly the period when Cole came into his own as a professional artist, travelled to Europe and painted his epic Course of Empire series.

Jackson is controversial nowadays for the politically correct reasons that he was a slave-owner who also took a tough line with native Americans, leading the US Army in the First Seminole War (1814 to 1819), and in 1830 signing an Indian Relocation Act which expelled native Americans from the South to the mid-West of America, causing an immensely destructive uprooting of peoples and cultures in which many died.

But contemporaries like Cole disliked Jackson not for these reasons, but because he was a demagogic populist who appealed over the heads of the Washington establishment to the broader electorate, claiming to speak up for ‘the common man’.

Several art scholars were on hand at the press view I attended and one of them said that Jackson was ‘the Donald Trump of his day’, claiming to stand up for the common man, but in reality paving the way for the spread of industrial capitalism into the West.

He said that if the figure in a red cloak riding in triumph across the viaduct in The Consummation of Empire can be seen as Jackson/Trump, then his empress, seated on a throne at the extreme right and bottom of the picture, must be Melania!

Why did Cole dislike Jackson so much? Because he objected to Jackson forcefully encouraging the opening up of the West for settlement and exploitation.

For Cole is seen by many as not only the first serious painter of landscapes in America, and founder of the Hudson River School of art, but also as one of the first American environmentalists.

Cole was deeply fearful that the Americans were about to repeat the mistakes he had witnessed at first hand in Britain, and were about to destroy their natural landscape in a misguided quest for industrialisation and ‘progress’.

This wasn’t just an opinion he expressed in painting. In 1836, while he was working on the Course of Empire paintings, Cole felt strongly enough about it to write an ‘Essay on American Scenery’ pleading for the preservation of the American wilderness.

Coincidentally and ironically, the same year saw construction begin on the Hudson Valley railway. In the final room, among other works, there’s a pairing of paintings Cole did before and after the railway was built through his beloved Catskill landscape.

The commentary very usefully pointed out the way Cole uses techniques borrowed from Claude Lorraine, namely the elegant trees framing the view, at the right, and the big eggshell blue sky, to convey a tremendous sense of openness and tranquility, against which his characteristically tiny people are framed.

The ‘after’ painting, made six years later in 1843, hardly depicts the end of the world; the changes are more subtle.

A moment’s attention shows that the trees have gone. The framing pair at the right of the earlier work, and the smaller one on the left, have disappeared, replaced by hacked-down stumps. Worse, where the entire lake was previously lined by an elegant sweep of trees, now these have all gone, replaced by low-growing bushes. Removing the trees eliminates the sense of depth and mystery from the view.

The railway itself cuts across the middle distance and this also, once you focus on it, has a subtly undermining effect. Previously the view unfolded with a sense of limitless depths, a sense of mystery succeeding wooded mystery. Now, denuded of trees and bisected by this subtle but decisive line, the entire landscape now appears somehow more constrained and controlled.

The highlight of the last room is arguably Cole’s most famous painting into which he poured everything – his management of sheer scale and size, his sense for landscape, everything he had learned from Turner and Constable about clouds – all expressed in yet another realistic painting which lends itself to allegorical interpretation – View from Mount Holyoke, Northampton, Massachusetts, after a Thunderstorm, generally known as The Oxbow.

This is a huge and hugely enjoyable painting, with much to note and savour. Moving from left to right, up in the sky, we pass from a violent thunderstorm (with forked lightning at the extreme left), to the storm petering out, whiter clouds and then a clear blue sky appearing.

This movement is paralleled on the earth by a movement from violently broken trees in the left foreground and dense virgin brush in the middle-left, suddenly giving way with a great sense of release to a huge vista down over the river valley to the mountains beyond.

And down in the river valley – in striking contrast to the dark, dark green of the wild brush in the left foreground, is the honey yellow of wheatfields in which stand tiny stooks of wheat. Scattered among the orderly yellow and light green fields are occasional settlements of good, honest, horny-handed farmers. Down at the bottom right is a ford with a few horses coming down to it and a raft crossing the river.

This is Cole’s vision of what America should be like, a land of free-living independent yeoman-farmers – the polar opposite of the urbanisation, the galloping desecration of the wilderness, and the encouragement of rapid industrialisation, all of which were taking place under Jackson’s presidency.

It was staring me in the face but I didn’t notice until one of the art historians pointed it out, that the river doesn’t just form a sharp loop – it is in the shape of a question mark. Which future will America choose, a federation of independent farmers, or go down the ruinous path of the Britain which Cole had himself escaped, towards industrialisation, environmental ruination and the transformation of free agricultural workers into a wretched proletariat?

More light-heartedly, Cole has painted himself into his work. At the bottom, just to the right of centre, you can see his head and hat emerging from behind a log. Here I am. I’m painting this beauty. What are you going to make of it?

The Oxbow has never been seen in the UK before. It is just one of about 20 paintings which are normally based in America, are rarely displayed together, and are well worth paying the admission price to see and savour.

Chapter 7. Cole’s Legacy

The final wall in the exhibition shows us the works of some of the painters who inherited Cole’s mantle. He died suddenly aged only 47, but not before he had taught the talented Asher Brown Durand and the exceptional Frederic Edwin Church. They both absorbed Cole’s practice of direct observation of nature, sketching and painting on site in the open air. There are several works by Durand and Church to assess them by.

Ironically, although Cole’s style and approach expanded into an entire ‘school’, almost all of his followers dropped his environmental concerns and adopted the new spirit of the times, the infectious optimism that America’s expansion West, its development and industrialisation, all represented a Manifest Destiny to become God’s Own Country.

Durand’s Progress (The Advance of Civilisation) was painted in 1853, just five years after Cole’s death, yet it celebrates the nascent taming of the wilderness.

At bottom right some cattle are being rounded up while a wagon is being driven up the road. To its left we can see a canal with a lock in it, over which, a bit further down, what looks like a railway bridge crosses over.

On a spur of land sticking out into the lake, in the distance, is some kind of town with a cluster of chimneys emitting the kind of smoke we saw in the first room of the gallery, denoting the British Industrial revolution. Meanwhile, half hidden among the broken trees to the left, is a group of three native Americans looking on – with awe, with regret, who knows? – but in effect characters made to pose and gaze in wonder at the unstoppable Progress of the White Man.

Absences and contradictions

There’s no slavery in Cole’s paintings. There are few native Americans. Politically correct curators can point out what – to our enlightened times – are these notable absences.

But then again there are no working poor of any kind. Farms we see, from a great distance, in The Oxbow, but none of the early starts and long days and hard manual labour involved in farming.

In fact people in general are conspicuous by their absence from Cole’s painting. Having never had a formal training, he was self-conscious about his ability to draw bodies and faces and so limited his depictions of people to distant puppets.

In any case, all this was part of his overall strategy, which was to cleanse the landscape of its human inhabitants (white or black or red) in order to present it as a bountiful and idyllic wildscape.

For example, the wall label tells us that there were already tourists at Niagara Falls, roads to bring them there and accommodation for them to stay in. But all of this was omitted from Cole’s primitivising vision of Niagara Falls (above).

The great irony of his career and art is, Who did he produce these visions of a pristine nature for, who did he sell them to?

The answer: to rich patrons in New York and Connecticut who had become rich precisely by laying roads across the wilderness, by selling dry goods to new settlements and, in the case of the New York bankers who patronised Cole, by funding the new railroads and industrial enterprises which were despoiling the very landscapes they paid him to paint.

Cole is praised as a founding environmentalist – but he is just as much a forerunner of that familiar figure, the modern artist who uses art to rail against capitalism, the West, exploitation, poverty and so on but – makes a career by selling their work to rich bankers or to art institutions founded and endowed by rich bankers, the lynchpins of the very system they purport to criticise.

A rapture of beauties

This exhibition would be worth visiting for the Cole alone, but the National Gallery has given us a real embarras de richesses by including masterpieces by the four European painters who most influenced him:

  • the enormous Snowstorm by Turner (Tate)
  • the ludicrously melodramatic Belshazzar’s Feast by John Martin (Yale, USA)
  • as well as five works by John Constable including Hadleigh Castle (Yale, USA) the Opening of Waterloo Bridge (Tate) and three beautiful sketches all usually kept at Yale University in the States, including some wonderful sketches of clouds

Cole developed a friendship with Constable and they exchanged letters and sketches. In fact there are a number of studies by Constable and Turner of skies, cloudscapes and so on, to compare and contrast with Cole’s own sketches. Some of the Constable ones are stunningly skilful uses of paint.

In fact one of the most fascinating snippets or sidelights of the exhibition was being shown the relationship between Cole’s anti-industrialising ethos and Constable’s similar sentiments. I hadn’t noticed before that the south bank of the Thames in the Opening of Waterloo Bridge (at the far right of the painting) is thronged with factory chimneys spewing out toxic smoke. Apparently, in his final years, Constable was depressed at the arrival of industrial blight in the landscape of the south of England.

I last saw The Opening in a large exhibition of Constable and powerfully disliked it. The curator pointed out that so does everyone else, but that was part of its point. It is an English version of Cole’s The Consummation of Empire, showing foolhardy pomp and circumstance while in the background industrialism is beginning to corrupt and destroy the culture.

Last but not least in the room showing enormous paintings which influenced Cole is Seaport with the Embarkation of Saint Ursula by Claude Lorraine. You can immediately see how his light-filled combination of water with classical buildings was absorbed and repurposed by Cole for the Course of Empire series, but there are plenty of pleasures to linger and enjoy just in this one painting.

The point is, this exhibition isn’t just about Cole. If you add in the couple of paintings each by Durand and Church to the Claude, Turner, Constable and Martin, the feeling is of encountering masterpiece after masterpiece in an exhibition which expands your mind and gladdens the heart.

While the rational mind is processing a raft of issues and ideas, the eyes are surfeited with quite rapturous beauty.

A Closer Look: Colour by David Bomford and Ashok Roy (2009)

This is another superbly informative, crisply written and lavishly illustrated little book in The National Gallery’s A Closer Look series. To quote the blurb:

A Closer Look: Colour explores how painters apply colour, describes different types of pigments, and outlines optical theories and artists’ treatises. The authors explain the effect on colour of the artist’s chosen medium, such as oil, water or egg tempera, and the dramatic impact of new pigments.’

It ranges far and wide across the National Gallery’s vast collection of 2,300 art works, selecting 80 paintings which illustrate key aspects of colour, medium and design. The quality of the colour reproductions is really stunning – it’s worth having the book almost for these alone and for the brief but penetrating insights into a colour-related aspect of each one.

They include works by Seurat, Holbein the Younger, Corot, Duccio, David, Chardin, Ghirlandaio, Monet and Van Dyck in the first ten pages alone!

Aspects of colour

Colour quite obviously has been used by painters to depict the coloured world we see around us. But it has other functions, too. Maybe the two most obvious but easily overlooked are: to represent depth and create the optical illusion of three dimensions on a two dimensional surface; and to reinforce this by indicating sources of light.

Depth A common indication of depth is recreating the common observation that objects at a distance fade into a blue-ish haze. This is often seen in Renaissance paintings depicting increasingly hazy backdrops behind the various virgins and main figures. This is known as aerial perspective.

Light Sources of light need to be carefully calculated in a realistic painting. The book shows how the effect of light sources is achieved by showing glimmers of white paint on metallic objects or even on duller surfaces like wood. There is a particularly wondrous example in Lady Elizabeth Thimbelby and her Sister by Anthony Van Dyck. The authors give a close-up to show how the colour of the yellow dress worn by the main subject is reflected on the bare skin of of the little angel, and even in the catchlight in his right eye, an indication of the depth of thought which goes into his compositions.

Shadows turn out to be an entire subject in themselves. For centuries painters improved their depiction of shadows, at first using grey colours for the shadows of buildings, but quickly realising that the most shadowed things around us are fabrics. Dresses, cloaks all the paraphernalia of costume from the Middle Ages to the turn of the 20th century, involved reams of material which folded in infinite ways, all of them a challenge to the painters’ skill. At the very least, painting a fabric requires not one but three colours: the core colour of the fabric itself, the fabric in shadow, the fabric in highlight, reflecting the light source.

The human eye is not a mechanical reproducer of the world around us. It has physiological quirks and limitations. The book evidences the way that, dazzled by orange sunsets, the human eye might well see evening shadows as violet. Quirks and oddities like this were known to various painters of the past but it was the Impressionists who, as a group, set out to try and capture not what the rational mind knew to be the colour, but the colours as actually perceived by the imperfect eye and misleadable mind.

Emotion In the later 19th century artists across Europe made the discovery that intensity of colour can be used to reflect intensity of emotion. Probably the most popular painter to do this was van Gogh whose intense colours were intended to convey his own personal anguish. This approach went on to become the central technique of the German Expressionist painters (although they aren’t represented in the book, along with all 20th century art, because the National Gallery’s cut-off point is 1900).

Symbolism In earlier centuries, more than its realistic function, colour had an important role in a painting’s symbolism i.e. certain colours are understood to have certain meanings or to be associated with certain people or qualities. The most obvious period is the Renaissance, when the Virgin Mary’s cloak was blue, Mary Magdalene’s cloak was red, St Peter’s cloak was yellow and blue, and so on. From early on this allowed or encouraged Renaissance painters to create compositions designed not only to show a (religious) subject, but to create harmonious visual ‘rhythms’ and ‘assonances’ based on these traditionally understood colour associations.

Pigments and Media

This is dealt with quite thoroughly in another book in the series, Techniques of Painting. There we learn that paint has two components, the binding medium and the pigment. Over the centuries different pigments have been used, mixed into different binding mediums, including egg, egg yolks, oil, painting directly into wet plaster (fresco) and so on.

Painting is done onto supports – onto walls, plaster, or onto boards, metal, canvas or other fabrics. All of these need preparing by stretching (canvas) or smoothing (wood), then applying a ground – or background layer of paint – to soak into the support. Painters of the 14th and 15th centuries used a white ground. In the 16th, 17th and 18th centuries, artists experimented with varying the tone of the ground, which significantly alters the colour of the works painted onto them.

Hardening Binding mediums dry out in two ways: watercolours and synthetic resin paints by simple evaporation. Drying oils such as linseed, walnut or poppy oil harden by chemical reaction with the oxygen in the air. Egg tempera, used extensively in the 14th and 15th century, dries by a combination of both.

This may sound fairly academic but it profoundly affects the whole style and look of a painting. Because tempera dries so quickly (especially in hot, dry Italy) shapes and textures are best built up by short hatched strokes.

This is a detail from the Wilton Diptych (1397) where you can see the way the skin of the Virgin and child and angels has been created by multiple short paint strokes of egg tempera.

Whereas, because oils are slow drying, they allow the artist to merge them into smooth, flowing, continuous transitions of colour. Oil paints = more flowing.

In this detail from Belshazzar’s Feast by Rembrandt, you can see how the gold chain has been rendered with a really thick layer of gold paint. Laying on very thick layers of oil paint is called impasto.

In general, oil paint looks darker and richer than paint made using water-based media such as egg tempera, glue or fresco, which appear lighter and brighter.

Age and decay Painting was, then, a highly technical undertaking, requiring the painter to have an excellent knowledge of a wide range of materials and chemical substances. Different media dry and set in different ways. Different pigments hold their colour – or fade – over time. And this fading can reveal the ground painted underneath.

One of the most interesting aspects of the book is the specific examples it gives of how some pigments have faded or disappeared – sometimes quite drastically – in Old Master paintings.

In Duccio’s The Virgin and Child with Saints Dominic and Aurea, the face and hands of the figures show clearly how the lighter pigments painted in tempera have faded or flaked off allowing the green underpaint to come through. The Virgin was not meant to look green!

Bladders to tubes Pigments had to be ground by hand and mixed in with binders in studios for the medieval and Renaissance period. There are numerous prints showing a Renaissance artist’s studio for what it was, the small-scale manufactory of a craftsman employing a number of assistants and making money by taking on a number of students.

In the 18th century ready-mixed pigments could be transported inside pigs’ bladders. The early 19th century developed the use of glass or metal syringes. But it was in 1841 that an American, John Rand, developed the collapsible metal tube. This marked a breakthrough in the portability of oil paints, allowing artists to paint out of doors for the first time. A generation later a new school arose – the Impressionists – who did just this. Jean Renoir quotes his father, the painter Pierre-Auguste, as saying:

Without paints in tubes there would have been no Cézanne, no Monet, no Sisley or Pissarro, nothing of what the journalists were later to call Impressionism.

Biographies of colours

Primo Levi wrote a classic collection of short stories based on The Periodic Table of chemical elements. It crossed my mind, reading this book, that something similar could be attempted with the numerous pigments which artists have used down the ages.

This book gives a potted history of the half a dozen key colours. It explains how they were originally produced, how different sources became available over the centuries, and how the 19th century saw an explosion in the chemical industry which led to the development of modern, industrially-manufactured colours.

Blue

  • Prime source of blue was the ultramarine colour extracted from the mineral lapis lazuli, which was mined in one location in Afghanistan and traded to the Mediterranean.
  • A cheaper alternative was azurite, which was mined in Europe but had to be ground coarsely to keep its colour, and is also prone to fade into green, e.g. the sky in Christ taking Leave of his Mother by Albrecht Altdorfer (1520). Many artists painted a basic wash of azurite and then used the much more expensive ultramarine to create more intense highlights.
  • Indigo is a dye extracted from plants. At high intensity it is an inky black-blue, but at a lesser intensity also risks fading.
  • A cheaper alternative was smalt, manufactured by adding cobalt oxide to molten glass, cooling and grinding it to powder. It holds its colour badly and fades to grey.
  • In the early 1700s German manufacturers stumbled across the intense synthetic pigment which became known as Prussian blue (the book gives examples by Gainsborough and Canaletto).
  • Around 1803 cobalt blue was invented.
  • In 1828 an artificial version of ultramarine was created in France

Thus the painters of the 19th century had a much wider range of ‘blues’ to choose from than all their predecessors.

The book does the same for the other major colours, naming and explaining the origin of their main types or sources:

Green

  • Terre verte was used as an underpaint for flesh tones in early Italian paintings
  • malachite
  • verdigris, a copper-based pigment was prone to fade to brown and explains why so many Italian landscapes have the same orangey-brown appearance
  • emerald green (a pigment developed in the 19th century containing copper and arsenic)
  • viridian (a chromium oxide)

Red

  • Vermilion, obtained by pulverising cinnabar, liable to fade to brown as has happened with the coat of Gainsborough’s Dr Ralph Schomberg (1770), which should be bright red.

Yellow

  • Lead-tin yellow in the Renaissance
  • from the 17th century lead-based yellow containing antimony known as Naples yellow
  • from the 1820s new tints of yellow became available based on compounds of chromium of which chrome yellow is the most famous
  • cadmium yellow

White

  • Lead white was used from the earliest times. It forms as a crust on metallic lead exposed to acetic acid from sour wine – highly poisonous
  • only in the twentieth century was it replaced by non-toxic whites based on zinc and later, titanium. Unlike all the pigments named so far, lead white keeps its colour extremely well, hence the bright white ruffs and dresses in paintings even when a lot of the brighter colour has gone.

Black 

  • A large range of black pigments was always available, most based on carbon as found in charcoal, soot and so on. Carbon is very stable and so blacks have tended to remain black.

Summary of colours

  1. Over the past 500 years there has been a large amount of evolution and change in the source of the pigments artists use.
  2. Colour in art is a surprisingly technical subject, which quite quickly requires a serious knowledge of inorganic chemistry and, from the 19th century, is linked to the development of industrial processes.
  3. Sic transit gloria mundi or, more precisely, Sic transit gloria artis. The net effect of seeing so many beautiful paintings in which the original colour has faded – sometimes completely – can’t help but make you sad. We live among the wrecks or decay of thousands of once-gloriously coloured artworks. Given the super-duper state of digital technology I wonder if anywhere there exists a project to restore all these faded glories to how they should look!

Disegno versus colore

Vasari, author of The Lives of the Great Artists (155) posed the question, ‘Which was more important, design or colour?’ As a devotee of Michelangelo, the godfather of design, he was on the side of disegno and relates a conversation with Michelangelo about some paintings by Titian (1488-1576) they had seen where Michelangelo praises Titian’s use of colour but laments his poor composition.

The art history stereotype has it that Renaissance Florence was the home of design, while Venice (where Titian lived and worked) put the emphasis on gorgeous colours. This was because Venice was a European centre for the production of dyes and pigments for a wide range of manufacturing purposes, not least glass and textiles.

In late-17th-century France the argument was fought out in the French Academy between Rubénistes (for colour) and Poussinistes (for drawing). Personally, I am more moved by drawing than colour, and a little more so after reading this book and realising just how catastrophically colour can fade and disappear – but, still, there’s no reason not to love both.

Optical theories

Isaac Newton published his Optics in 1704, announcing the discovery that when white light is projected through a prism it breaks down into primary colours, which can then be turned back into white light. Among its far-ranging investigations, the book contained the first schematic arrangement of colours and their ‘opposites’. It wasn’t until well into the 19th century, however, that colour charts began to proliferate (partly because they were required by expanding industrial manufacture, and the evermore competitive design and coloration of products).

And these colour charts bore out Newton’s insight that complementary colours – colours opposite each other on the circle – accentuate and bring each other out.

Colour Circle by Michel Eugène Chevreul (1839)

Colour Circle by Michel Eugène Chevreul (1839)

Colour circles like this systematised knowledge which had been scattered among various artists and critics over the ages. It can be shown that Eugène Delacroix (1798-1863) made systematic use of contrast effects, pairing colour opposites like orange-blue, red-green or yellow-violet, to create stronger visual effects.

On a simplistic level it was the availability of a) new, intense colours, in portable tin tubes, along with b) exciting new theories of colour, which explains the Impressionist movement.

The Impressionists were most interested in trying to capture the changing quality of light, but the corollary of this was a fascination with shadow. Apparently, impressionist painters so regularly (and controversially) paired bright yellow sunlight with the peculiar tinge of violet which is opposite it on the colour charts, that they were accused by contemporary critics of violettomani.

Some examples

The book lists the pigments used to create Titian’s Bacchus and Ariadne. The intense blue sky is made from ultramarine lapis lazuli, as is Ariadne’s drapery and the flowers at the lower right. The blue-green sea is painted with the cheaper azurite. Vermilion gives Ariadne’s sash its red colour. The Bacchante’s orange drapery was painted with a rare arsenic-containing mineral known as realgar.

Titian was aware of the power of colour contrasts long before the 19th century colour wheels, something he demonstrates by placing Ariadne’s red and blue drapery above the primrose yellow cloth by the knocked-over urn at her feet (painted using lead-tin yellow). The green of the tree leaves and the grassy background are created from malachite over-painted with green resinous glazes. An intense red ‘lake’ is used to give Bacchus’s red cloak its depth.

These coloured ‘lakes’ were an important element in Renaissance painting but I had to supplement the book’s information with other sources.

From this I take it that ‘lakes’ were translucent i.e. you could see the colour beneath, and so were used as glazes, meaning you would lay down a wash of one colour and then paint over potentially numerous ‘lakes’ to add highlights, depths or whatever. This build-up of ‘lake’ glazes allowed the layering of multiple variations of colour and so the intensely sensual depiction of the folds on fabrics, the light and shade of curtains and clothes which is so characteristic of Old Master painting.

The book then applies this detailed analysis of colour pigments to a sequence of other Old Masterpieces by Rubens, Velázquez, Rembrandt, Tiepollo, Canaletto, Monet and Seurat.

Conclusion

A Closer Look: Colour makes you appreciate the immense amount of knowledge, science, craft and technique which went into painting each and every one of the National Gallery’s 2,300 artworks (and the depth of scholarship which modern art historians require to analyse and unravel the technical background to each and every painting).

It’s a revelation to read, but also pure joy to be prompted to look, and look again, in closer and closer detail, at so many wonderful paintings.
