Book 9 of Ovid’s Metamorphoses ended with several obscure myths that have been painted little, but Book 10 opens with one of the greatest and most enduring stories of the European canon: that of Orpheus and Eurydice. Ovid links to this through Hymen, the god of marriage, and the wedding of Eurydice to the outstanding musician and bard Orpheus. It was a wedding marred by tragedy: after the ceremony, just as the bride was wandering in joy with Naiads in a meadow, she was bitten by a snake on the heel, and died.

Among the earliest paintings of this story in the post-classical era is Jacopo da Sellaio’s superb panel showing Orpheus, Eurydice and Aristaeus from 1475-80. This is one of a series that’s now dispersed across continents. It employs multiplex narrative to show the start of the story, with Orpheus left of centre, tending a flock of sheep, as his bride is bitten by the snake. At the far right, Orpheus, with the assistance of Aristaeus, puts Eurydice’s body in a rock tomb.

One of Poussin’s most famous narrative works, Landscape with Orpheus and Eurydice (c 1650-53) shows Orpheus with his lyre at the right, and Eurydice standing in white, as a snake approaches from the left. Poussin had a thing about snakes, and painted other landscapes with snakes threatening people, and his enigmatic Landscape with a Man Killed by a Snake (c 1648). Here his normally peaceful rustic landscape is showing ominous signs of falling apart: the distant castle is on fire, with smoke billowing into the sky.

In Eurydice and the Serpent, a pastel from 1915, Ker-Xavier Roussel shows them just a moment before the bite, with the snake seen on the ground in front of her.

Ary Scheffer’s moving painting of Orpheus Mourning the Death of Eurydice is one of his early works from about 1814. The snake is still visible at the far left, and Orpheus cradles the limp body of his new bride, and breaks down in grief. Scheffer’s handling of complex limb positions is masterful, with the symmetry of their right forearms, and the parallel of her left arm with his left leg. His lyre rests symbolically on the ground behind his left foot.

Orpheus was heart-broken, and mourned her so badly that he descended through the gate of Tartarus to Hades to try to get her released from death. He came across Persephone and her husband Hades, and pleaded his case before them. He said that, if he was unable to return with her to life on earth, then he too would stay in the Underworld with her. He then played his lyre, music so beautiful that those bound to eternal chores were forced to stop and listen. Tantalus, Ixion, the Danaids, even Sisyphus paused and sat on the rock that he normally tried to push uphill. The Fates themselves wept with emotion.

Henri Regnault’s Orpheus in the Underworld (1865) was probably based more on the popular opera by Offenbach, first performed in 1858. Orpheus is seen at the left, his lyre in his hand, singing to the dead. Behind him, at the left edge, are two of the heads of Cerberus, who guards the entrance to the Underworld, and sat on the double throne at the upper right are Persephone, who only spends half the year in the Underworld, and Hades himself.

Persephone summoned Eurydice, and let Orpheus take her back, on the strict understanding that at no time until he reached the earth above could he look back, or she would be returned to the Underworld for ever.

Peter Paul Rubens’ atmospheric painting of the flight of Orpheus and Eurydice (1636-38) was made during his later years of retirement, a few years before his death. Orpheus, clutching his lyre, is leading Eurydice away from Hades and Persephone, as they start their journey back to life. He opts for an unusually real-world version of Cerberus at the bottom right corner.

Camille Corot’s Orpheus Leading Eurydice from the Underworld (1861) shows the couple as they near the light at the exit of the underworld. He is instantly recognisable by his lyre held high in front of him, and both are moving towards the right edge of the painting, the edge of the dark wood. Rather than use an abstract form to represent the underworld, Corot has used a wood, with a pool in the middle distance. Behind that are spirits of the dead, some still grieving their death.

Edward Poynter’s Orpheus and Eurydice (1862) takes the couple on an arduous journey, striding past snakes and along a dizzying path on the mountainside. While he looks straight ahead, she seems to be struggling to keep up.

John Roddam Spencer Stanhope’s Orpheus and Eurydice on the Banks of the Styx (1878) takes the couple further still, onto the bank of the River Styx, where Orpheus is summoning Charon the boatman to take them back across the water. He clutches her closely and still looks straight ahead, the couple bound together by the black sash of the Underworld.

The couple trekked up through the gloom, and were just reaching the brighter edge of the Underworld when Orpheus could resist no longer, and looked back to make sure that his wife was still coping with the journey. The moment that he did she melted away back into Hades’ realm. As he tried to grasp her, his hands clutched at empty air. She was gone.

It’s hard to know whether George Frederick Watts’ undated painting of Orpheus and Eurydice shows Orpheus embracing the dead body of Eurydice immediately after she has been bitten by the snake, or (more probably) Orpheus clutching in vain at her spirit as it melts away back into the Underworld, after he has looked back.

Orpheus tried to persuade the ferryman to take him back across the River Styx into the Underworld, but was refused. For a week he sat there in his grief. He then spent three years shunning the company of women, despite their attraction to him, and brought shade to an exposed meadow with his singing, leading to the next myth.

The final painting in this series is Gustave Moreau’s Orpheus at the Tomb of Eurydice (c 1891), showing the bard, his ghostly lyre slung from the dead treestump behind him, lamenting the loss of Eurydice after his failed attempt to bring her back from the Underworld. Moreau painted this dark and funereal work to mark his own inconsolable grief at the death of his partner, Alexandrine Dureux.

Sage and wise people are harder to distinguish visually, without using the cliché of the white-haired and bearded figure more commonly seen as Father Time. To the Romans, the personification of Wisdom was the goddess Minerva or Athena, whose complex background proved a challenge for painters.

Hendrik Goltzius shows a classical and fairly complete set of her attributes: the owl, her distinctive helmet here decorated with olive leaves, a spear, books, a writing quill, and great beauty.

Athena may go back to an even earlier Mycenean goddess. In archaic images, she’s often seen with an owl perched on her hand, and there is a suggestion that she may have originally been a bird goddess, nearly two thousand years BCE. Whatever the origins, there’s no doubt that Athena then Minerva were goddesses of wisdom, learning, crafts, and skill, and that they were strongly associated with owls, who became proxies for wisdom and knowledge. Minerva of the Romans also had Etruscan influences that determined her name in the goddess of war Menrva, with origins from an Italic moon goddess of similar name, hence her helmet and spear.

Solon was a key figure in the development of classical Greek civilisation, most significantly for laying down the tables of law for Athens, and best known for his legendary involvement with Croesus, the fabulously rich king whose name endures in English and other languages in the phrase as rich as Croesus.

Gaspar van den Hoecke’s Croesus Showing his Treasures to Solon is one of several similar paintings made in about 1635, presumably from a common source; others attributed to Cornelis de Vos and Frans Francken II survive. Here Croesus at the right is showing the bald and bearded Solon one of his treasure chambers. Troops in the background may refer to Croesus’ imminent fate at the hands of Cyrus and his Persian forces.

Accounts of wisdom in the Old Testament are generally focussed on the judgement skills of King Solomon, as displayed when he was called to settle a dispute between two women claiming to be the mother of one baby. Solomon commanded that the infant should be cleaved in two by a sword, leading to the real mother relinquishing her claim to the child, to ensure its survival.

Nicolas Poussin’s famous painting of The Judgement of Solomon from 1649 is timed slightly before the sword is raised, and depicts the body language clearly. Solomon’s hands indicate his role as the arbiter, in showing a fair balance between the two sides. The true mother, on the left, holds her left hand up to tell the soldier to stop and spare the infant. Her right hand is extended towards the false mother, indicating that she has asked for the baby to go to her rather than die. The false mother points accusingly at the child, her expression full of hatred. Hands are also raised in the group at the right, suggesting reactions to Solomon’s judgement. Without knowing the story well, though, there are no visual cues to suggest this young king is exceptionally wise.

This panel attributed to Giorgione and dated around 1505 mirrors the composition of his Trial of Moses (c 1496-9), to which it might have been a pendant. Solomon is shown in advanced age, thus inherently wise, commanding a courtier who has raised his short sword ready. The two women straddle the midline of the panel, their body language not clear enough to indicate who is the true mother.

More problematic still are visual accounts of the adoration of the Magi, three ‘wise men’ who are drawn by their observations of a comet to pay homage to the infant Jesus. Most take the easy option of depicting them as three kings, and only a few show them as pioneering astronomers.

Giotto’s frescoes in the Scrovegni Chapel at Padua, Italy, show a more elaborate depiction of The Adoration of the Magi (c 1305). The infant Christ rests on the Virgin Mary’s knee; she was originally clad in her signature ultramarine blue, but that has worn away with the years. Mary is accompanied by Joseph and an angel, and the Holy Family is within a wooden shed. The three Magi pay their respects and present their gifts, accompanied by camels and at least two attendants. The comet that attracted their attention is shown as a fireball crossing the sky.

Diego Velázquez broke with tradition in his Adoration of the Magi from 1619 in depicting the figures as real humans rather than idealised models. He had to be careful to maintain distinct appearances for those such as Mary and Jesus who are divine, even covering the Virgin’s feet for the sake of propriety. But the other figures here all look to be real, living and breathing people, and the Magi for once aren’t visual clichés.

With the Age of Enlightenment, paintings came to include the most enlightened in more innovative ways, as ‘philosophers’, particularly in the chiaroscuro images of Joseph Wright of Derby.

In 1766, Wright exhibited one of his most enduring images of the period, A Philosopher Giving that Lecture on the Orrery, in which a Lamp is Put in Place of the Sun. The orrery, a miniature planetarium showing the movements of the planets and their moons, was an impressive high-end Grand Orrery, an expensive device that would undoubtedly have captivated the minds of those able to gaze at it.

There are numerous cues here to different narratives: to Locke’s educational theories with their emphasis on geography, understanding of astronomy, and Newton’s gravitation and mechanics. It has been proposed that the philosopher in the red gown is modelled on Isaac Newton, and the figure at the left taking notes is Wright’s friend Peter Perez Burdett.

In the nineteenth century, wisdom was strongly associated with science and technology, and the equipment used.

Joaquín Sorolla’s Portrait of Dr. Simarro at the Microscope from 1897 shows Doctor Luis Simarro Lacabra (1851-1921), who was an eminent psychiatrist in Madrid, and undertook pioneering research looking at the fine structure of the brain. Among his many achievements was a modification of an established technique for staining microscopic sections of brain, which proved a major advance and an inspiration to the great Spanish neurohistologist Ramon y Cajal. He is shown here with one of the most popular scientific instruments associated with knowledge and wisdom, the microscope.

Few artists have ever gathered as many of the great and wise as Raphael, in his large fresco of The School of Athens, painted between about 1509-10.

This wasn’t recognised as depicting eminent Greek philosophers until 1695, with Vasari’s account in his biography of Raphael assuming that it included a group of evangelists, and others claiming the figures are taken from Dante’s Divine Comedy.

This assorted collection of Greek philosophers, with a few extras, are chatting, teaching, and generally loafing about in an impressive building of grand classical style that is probably Raphael’s extended fantasy based on the contemporary architecture of Bramante. Although there’s no coherent narrative, it contains numerous diverting scenes in which the viewer is challenged to recognise the participants.

The central figures are Plato (left), who carries in his left hand a book titled TIMEO, and Aristotle (right), whose book bears the word ETICA. Seen further to the left in profile is Socrates, and below him is Pythagoras, who is writing in a book while a boy holds in front of him a small blackboard showing the theory of harmony.

His opposite number on the right is Euclid, who is bent over and holding a pair of compasses in his right hand. Behind him are Ptolemy, who is holding a globe and facing away, and Zoroaster, who holds a celestial sphere with his right hand. One striking figure for which I haven’t seen any plausible identification is the woman behind Pythagoras, who appears to have just walked out of Leonardo da Vinci’s Mona Lisa.

As Ovid draws Book 8 of his Metamorphoses to a close, Lelex has just told the touching story of Philemon and Baucis, who were transformed into an intertwining pair of trees. Achelous, host of the banquet, then takes over as narrator, to tell of three examples of shape-shifters, who can transform whenever they want.

His first example is probably the most accomplished of all: Proteus, who apparently can transform himself into all manner of creatures and objects, at one moment a boar, the next a snake or a fire. Both Hans Thoma and Cy Twombly have painted Proteus, but I regret that neither of their works is available to show here.

This leads Achelous on to tell the longer story of another shape-shifter, the daughter of Erysichthon, who remains unnamed here, elsewhere being known as Mestra or Mnestra. But he first has to introduce her father, by telling the story of his downfall.

Erysichthon was an irreligious man, even desecrating Ceres’ sacred grove by chopping down a giant and ancient oak within it. As he prepared to swing his axe at the tree, it shuddered and turned pale. A man stood in his way, so he was peremptorily beheaded. As he raised his axe ready, its nymph warned him that her death would bring him punishment.

The other Dryads (wood nymphs) prayed to Ceres to punish Erysichthon. The goddess decided to bring him insatiable hunger, but as it was decreed that Ceres and the goddess of hunger could never meet, Ceres sent an Oread as her messenger. The Oread found Hunger in the Caucasus mountains, and passed the message. Ovid then gives a detailed account of how Erysichthon was wracked with hunger, even in his dreams. Nothing could satisfy his appetite, and he spent his entire wealth trying to do so. When he ran out of money, he sold his own daughter to raise money for more food.

Erysichthon’s daughter then called on Neptune, who had previously raped her, to be spared from slavery. The god then transformed her into a fisherman, and her father, not recognising his daughter, called on the fisherman to tell him where his daughter had gone. She denied all knowledge of her former female self, and the man who had bought her went away. Knowing her ability to transform herself, Erysichthon sold her to a succession of people, enabling her to cheat on them and be sold again in a different form. He fed his constant hunger from the money she brought him, until he started to eat his own flesh and limbs.

Johann Wilhelm Baur’s engraving showing Erysichthon Sells His Daughter Mestra (c 1630) is a simple depiction of Ovid’s story, but has the interesting feature of Neptune, with his traditional horses and trident, down on the water to the right.

It’s Neptune and water that provide a thread running through much of Ovid’s narrative here. For Neptune not only raped Mestra and enabled her shape-shifting, but he is the father of Proteus, the most adept of all shape-shifters, and both Achelous and Neptune are gods of the waters. Neptune has been painted frequently, but I can find no reference to him being shown with his son Proteus, nor with Mestra. But there is one painting in which father and son might appear together.

Nicolas Poussin’s The Birth of Venus (1635-36) is controversial, as there is no general agreement as to what it is actually about, nor the identity of the goddess at its centre. One reading maintains that its current title is correct, and the central goddess is Venus, who has just been born from sea foam. To the left is clearly Neptune (Poseidon), bearing his trident, and astride his horses. In the far distance, riding on the clouds, Venus’ chariot is being towed towards her by swans.

There are other figures to identify, but one man in the distance at the left edge looks similar to Neptune, and could well be his son, The Old Man of the Sea, Proteus himself. An alternative interpretation is that it’s the sea nymph Galatea, being drawn on a chariot of cockleshells by a school of dolphins, at the centre, rather than Venus.

There is another more recent painting that appears to have been influenced by Poussin’s: William Dyce’s remarkable fresco in Queen Victoria’s holiday palace on the Isle of Wight, Osborne House.

In Dyce’s Neptune Resigning to Britannia the Empire of the Sea (1847), Neptune stands astride his three white seahorses with their fish tails, holding their reins in his right hand, and passing his crown with the left. The crown is just about to be transferred by Mercury (with wings on his cap) to the gold-covered figure of Britannia, who holds a ceremonial silver trident in her right hand. Neptune is supported by his entourage in the sea, including the statutory brace of nudes and conch-blowers. At the right, Britannia’s entourage is more serious in intent, and includes the lion of England, and figures representing industry, trade, and navigation.

The depiction of Neptune, and much of the left half of the painting, has more than a passing resemblance to Poussin’s. But look into the distance, below Mercury and behind Neptune, and there’s an Old Man of the Sea with two nymphs. Could that also be Proteus?

In the closing lines of the book, Ovid then reveals through Achelous the link to the start of Book 9: Achelous reveals that he too is a shape-shifter, able to transform himself into a snake or a bull. But that bull had recently lost one of its two horns, the basis of the next myth.
