Mermaids and mermen are mythical creatures with origins outside the classical Mediterranean civilisations. Conventionally, their upper body is human, while below the waist they have the form of a fish. Mermaids seem invariably young, beautiful and buxom, and are most frequently encountered by fishermen and those who go down to the sea. In the Middle Ages they became confounded with the sirens of Greek and Roman myth, who were part human and part bird.

John William Waterhouse’s diploma study for the Royal Academy, painted in 1900, shows a conventional image of A Mermaid, seen combing her long tresses on the shore.

Despite their separate origin, mermaids have been depicted in accounts of some classical myths, perpetuating medieval confusion.

Gustave Moreau’s Venus Rising from the Sea from 1866 shows the goddess as she has just been born from the sea, and sits on a coastal rock, her arms outstretched in an almost messianic pose. On the left, a mermaid attendant holds up half an oyster shell with a single large pearl glinting in it. On the right, a merman proffers her a tree of bright pink coral, and cradles a large conch shell.

Ary Renan’s Charybdis and Scylla (1894) is an imaginative painting of one of the dangers to mariners in the Strait of Messina, between Sicily and the Italian mainland. Scylla was said to be a six-headed sea monster, but was actually a rock shoal, and Charybdis was a whirlpool. Renan shows both together, the whirlpool with its mountainous standing waves at the left, and the rocks at the right, with the form of a beautiful mermaid embedded in them.

As the First World War was ending, Franz von Stuck returned to his favourite faun motif in A Faun and a Mermaid (1918). This has survived in two almost identical versions, the other now being in the Alte Nationalgalerie in Berlin. His version of a mermaid is a maritime equivalent of a faun, with separate scaly legs rather than the more conventional single fish tail. She grasps the faun’s horns and laughs with joy as the faun gives her a piggy-back out of the sea.

Perhaps the earliest painting of a mermaid in European art is in a Christian religious painting by Lucas Cranach the Elder, from 1518-20.

Cranach’s Saint Christopher shows the saint with his back and legs flexed as he bears the infant Christ on his left shoulder. In the foreground is an unusual putto-mermaid with a long coiled fish tail.

Mermaids feature in folktales from many of the traditions of Europe, where they’re known by local names such as havfrue in Denmark.

John Reinhard Weguelin’s watercolour of The Mermaid of Zennor (1900) tells the legend of a mermaid living in a cove near Zennor in Cornwall. This scene brings her together with Matthew Trewhella, a local chorister, whose voice she had fallen in love with. The legend tells that the couple went to live in the sea, and that his voice can still be heard in the cove.

Peter Nicolai Arbo’s Liden Gunver and the Merman (1874-1880) is drawn from an opera The Fishers, by Johannes Ewald and Johann Hartmann, first performed in Copenhagen in 1780. The young woman Liden Gunver, on the right, is taken to sea by the alluring but deceptive merman on the left.

Hans Thoma’s Three Mermaids (1879) lack fishtails as they frolic raucously with fish under the light of the moon.

Gustav Klimt’s Mermaids (Silverfish) (c 1899) appear to be tadpole-like creatures with smiling, womanly faces.

Although birth hasn’t proved such a popular theme in paintings, there are countless depictions of death. Dominant among them in European works are those of the Crucifixion, but in this brief survey I concentrate on those showing figures from myth, history and contemporary life, particularly those of deathbed scenes, and omit religious paintings entirely.

Adonis is perhaps the only figure whose birth and death have been popular in paintings. Following his strange birth from the myrrh tree, when he was a young adult he bled to death after he had been gored by a wild boar while he was hunting.

Hendrik Goltzius’ startlingly foreshortened projection of the Dying Adonis from 1609 pushes his face and head into the distance and makes their features almost unreadable, while his feet take pride of place and you can even read their soles.

Piero di Cosimo’s wonderful painting of a dying nymph uses the full width of a panoramic panel to show a satyr with his goat legs and distinctive ears, ministering to the nymph, who has a severe wound in her throat. At her feet is a hunting dog, with another three in the distance. Sometimes claimed to show the death of Procris by a javelin thrown by her husband Cephalus, this tells a different and unidentified story.

The death of Dido is more easy to identify, particularly in this depiction by Henry Fuseli, from 1781.

Dido has mounted her funeral pyre, and is on the couch on which she and Aeneas made love. She then fell on the sword which Aeneas had given her, and that rests, covered with her blood, beside her, its tip pointing up towards her right breast. Her sister Anna rushes in to embrace her during her dying moments, and Jupiter sends Iris (wielding a golden sickle) to release Dido’s spirit from her body. Already smoke seems to be rising up from the pyre, confirming to Aeneas that she has killed herself, as he heads towards the horizon, and the eventual founding of Rome.

The story of lovers Pyramus and Thisbe and their tragic deaths has been popular with painters since classical times. When they arrange to meet outside the city, she flees from a lioness, leaving her bloodied cloak. He then arrives and assumes that she has been killed by the lioness and falls on his sword. She returns to find him dying, and falls on his sword so they can be reunited in death. Their spilt blood turns the fruit of the mulberry bush from white to red.

This version from the ruins of Pompeii includes all the main cues, with the lioness in the distance, and a mulberry tree with its white fruit. Its composition has remained in use for the two millennia since then.

More recent legends, particularly those of King Arthur, have formed the basis for some notable painted deathbed scenes.

In James Archer’s The Death of King Arthur from about 1860, the dying Arthur is surrounded by four women, as the black boat approaches the beach behind them. At the right, the ghostly figure of an angel holding a chalice is materialising, in accordance with Sir Thomas Malory’s popular literary account.

Many historical figures have been portrayed in their final moments.

In Paul Delaroche’s Death of Elizabeth I, Queen of England (1828) the haggard queen is shown slumped on a makeshift bed on the floor, putting her low in the painting. Her maids and other female attendants are in distress behind her, supporting the pillows on which her head rests. I presume that the male kneeling by the queen and extending his right hand towards her is Robert Cecil, leader of the government at the time, and behind him are other members of the Privy Council of England, who were shortly to install Elizabeth’s successor.

Benjamin West’s best-known painting of The Death of General Wolfe (1770) shows a scene from an almost uniquely brief battle between British and French forces on 13 September 1759, which lasted only an hour or so. At the end of their three months siege of the French city of Quebec, Canada, British forces under the command of General Wolfe were preparing to take the city by force. The French attacked the British line on a plateau just outside the city.

Within minutes, Wolfe suffered three gunshot wounds, and died quickly. The French commander, General Louis-Joseph, Marquis de Montcalm, was also hit by a musket ball, and died the following morning. The British line held, and the French were forced to evacuate the city, ultimately leading to France ceding most of its possessions in North America to Britain, in the Treaty of Paris of 1763. Wolfe’s death was quickly seen as the ultimate sacrifice of a commander in securing victory, West’s underlying theme here.

Just over twenty years later, it was the turn of the French Revolution to provide a more equivocal hero.

On the morning of 13 July 1793, Charlotte Corday, a young woman from Normandy, turned up at the Paris house of Jean-Paul Marat, one of Revolution’s most influential radicals, asking to see him; his fiancée turned her away. She gained entry later that evening, and started giving him the names of some local counter-revolutionaries. While he was writing them down, she drew a kitchen knife with a 15 cm (6 inch) blade from her clothing, and plunged it into Marat’s chest, killing him rapidly.

David’s famous painting shows Marat’s body slumped over the side of his bath, the murder weapon and his quill both on the floor, the pen still in his right hand, and a handwritten note in his left hand. Corday was executed in public by guillotine on 17 July. Marat became a martyr for the cause, after his friend David had organised one of the spectacular funerals for which he had become known.

When Théodore Géricault, who had painted The Raft of the Medusa in 1818-19, died in Paris on 26 January 1824, the young and promising history painter Ary Scheffer painted his tribute as The Death of Théodore Géricault (1824). At the artist’s bedside are his close friends Colonel Bro de Comères and the painter Pierre-Joseph Dedreux-Dorcy, and the wall of the room is covered by his paintings.

When Claude Monet’s first wife was dying in the late summer of 1879, he painted his tribute to her in Camille Monet on her Deathbed (1879). She appears to be surrounded by diaphanous feathers that rise on either side of her head to form angelic wings. She was only 32, and they had two children.

By the Deathbed (1895) is Edvard Munch’s painting from memory of his sister Sophie resting in her deathbed in 1877, when she was 15 and the artist wasn’t quite 14 years old. She died of tuberculosis, an unfortunately common event at the time. Munch explained that, when painting from memory like this, he depicted only what he could remember, and was careful to avoid trying to add details that he no longer saw. This explains its relative simplicity.

Sophie is seen from her head, looking along her length to her feet, her figure compressed into almost nothing by extreme foreshortening. Her deathbed resembles the next step, in which her body will be laid out in a coffin prior to burial. More than half the painting is filled by the rest of the family, father with his hands clasped in intense prayer. At the right is their mother, who had died of tuberculosis herself nearly nine years earlier.

Like Manet and the French Impressionists, Marià Fortuny painted motifs that challenged social attitudes of the day. His portrait of Miss Del Castillo on her Deathbed from 1871 shows a similar scene to Monet’s later painting above.

Sometimes, deathbed and other posthumous portraits prove too great a challenge.

Maria Munk, known as Ria, had been engaged to the actor and writer Hanns Heinz Ewers; when he called off their engagement, she committed suicide just after Christmas in 1911, by shooting herself in the chest. Gustav Klimt was commissioned by Ria’s family to paint a posthumous portrait of her, and first made Ria Munk on her Deathbed, initially completed in 1912 but here dated to 1917-18. She is manifestly dead, and surrounded by floral tributes. The family rejected the work, finding it too distressing, and asked Klimt to depict her when she had still been alive, from photographs.

A second portrait completed in 1916 was also rejected, although there’s doubt about the identity of the painting, and the reason for its rejection. Klimt started his third attempt in 1917, and was still working on it early the following year. It was clearly going to be one of his richly decorated paintings, with abundant colourful flowers in the background, and brilliant peppers and other vegetables. In early January 1918, Klimt caught the deadly influenza that had just started to spread across Europe. He quickly developed pneumonia, suffered a stroke, and died on 6 February 1918.
