After he has told us of the birth of Hercules, Ovid uses Alcmena’s link with Hercules’ former lover Iole to introduce several obscure stories, starting with the transformation of Dryope.

Iole tells the tale of her sister Dryope, the fairest in all Oechalia. She had been raped by Apollo, then married Andraemon, by whom she had a baby boy. When her son was only one and still at the breast, Dryope and Iole came to a lake, and picked crimson water-lotus flowers to please the infant. They were horrified to see drops of blood on the foliage; these later turned out to be from the nymph Lotis, who had been transformed into that bush after fleeing from Priapus.

As Dryope tried to run away, she found herself literally rooted to the spot as she was transformed into a Lotus Tree, as punishment for picking the lotus flowers. Her distraught husband came and took his son away to be cared for by a nurse.

Baur’s engraving from about 1639 shows Dryope and Iole distant, at the right. As Dryope transforms into a Lotus Tree, she’s still holding her son, and Iole is praying to the heavens. Presumably the two males in the foreground are Dryope’s husband and a friend.

By the end of Iole’s story, Alcmena is in tears. They are then interrupted by Iolaus, Hercules’ former charioteer who took part in the Calydonian boar hunt, who had just been rejuvenated as a result of the intervention of Hercules, now a god, and Hebe, his heavenly wife.

Ovid briefly mentions the sons of Achelous’ daughter Callirhoe, whose years were advanced by Hebe to allow them to avenge their father’s murder. This in turn resulted in discord among the gods over Iolaus’ rejuvenation. Ovid uses this aside to link to the story of Byblis and Caunus, twins born to Miletus and the beautiful nymph Cyanee, the first of two concerning ‘unnatural love’ concluding book 9 of the Metamorphoses.

Byblis was strongly attracted to her twin brother Caunus. At first this was nothing more than sisterly love, but it grew into something more passionate, if not obsessive, as demonstrated in her long soliloquies. Eventually, Byblis decided the best way ahead was to write to her brother confessing her love for him. She did this on wax tablets, but kept erasing her words, until she eventually arrived at a long and elaborate message, given in full by Ovid, that she signed with her signet ring and despatched to Caunus via a slave.

On starting to read his sister’s message, Caunus flew into a rage, threw the tablets to the ground, and angrily sent the slave back to Byblis, with a clear message that his sister’s proposition was shameful. In another soliloquy, Byblis blamed herself for getting it so badly wrong, saying she shouldn’t have put her feelings in writing, but should have told them orally to her brother. She then pondered whether the slave had made some error, or that her brother had mistaken her true love for him for simple lust.

Becoming more confused and upset all the time, Byblis beat herself, tore her clothing, and ran through the countryside, until she fell on the ground by a forest. The wood nymphs there tried to comfort her, to no avail, as she dissolved in her tears to form a spring.

Despite its sensitive subject of an incestuous relationship, the story of Byblis and Caunus has appeared in a few paintings. In each case, they show Byblis’ transformation into a spring, or rather they provide an opportunity to paint a young nude woman outdoors.

Jean-Jacques Henner includes a spring of sorts, and some garments that have been cast off, not exactly torn, in his Byblis Turning into a Spring (1867).

This is a smaller version of Bouguereau’s painting of Biblis from 1884, the larger one having been exhibited at the Salon in 1885. His spring is more substantial, but there’s nothing to suggest that this wasn’t just another carefully posed nude.

This undated account by Armand Point, Biblis Changed into a Spring, reads a little more faithfully to Ovid’s story, but this image of it is too poor to see other potential narrative elements such as the figures in front of the temple at the left.

Ovid then concludes Book 9 of his Metamorphoses with one of his most remarkably insightful tales. I have to keep reminding myself that he wrote this over two thousand years ago, but the issues he considers are thoroughly modern, and his approach to the story of Iphis and Ianthe is sensitive even by current standards.

Ligdus lived in Phaestos in Crete, not far from the great Knossos. Telethusa his wife was pregnant with their first child. They weren’t rich, and as a consequence Ligdus told her that she had to bear him a son, as they couldn’t afford to have a daughter. If she were to give birth to a girl, he said the child would have to die. Telethusa begged her husband to accept a daughter, but he wouldn’t budge.

Late in her pregnancy, Telethusa had a vision of the Egyptian goddess Isis, with attendant deities. Isis told her to keep and rear the baby, whether it was a boy or girl, if necessary by deception. The goddess promised that she would answer her prayers and help in times of need. Telethusa promptly went into labour that morning, and was delivered of a girl. She followed Isis’ instruction and declared the child to be a boy. The couple then raised their daughter as a son named Iphis, a name ambivalent in gender.

Thirteen years later, Ligdus found his son a bride, Ianthe, and their match appeared excellent, each falling in love with the other. Iphis, though, knew that she was a girl, and became upset that because of her gender, their marriage couldn’t happen. She postponed the wedding, delayed it further, but eventually ran out of excuses, and a final date had to be fixed.

The day before their marriage, Telethusa prayed to Isis, with Iphis at her side. As they walked back together, Iphis was transformed into a man who then married Ianthe, and lived happily ever after, remembering to make offerings to Isis in thanks for the remarkable transformation.

As you can imagine, few if any patrons in the past would have commissioned artists to paint this story, although it has been tackled by those illustrating this book of the Metamorphoses.

Bernard Picart’s engraving Isis Appears to Telethusa, from about 1732, dodges the real issues at stake by showing Telethusa’s vision of Isis and her entourage of Egyptian deities.

Johann Wilhelm Baur was braver in his engraving, showing Isis Changing the Sex of Iphis (c 1639) shortly before the wedding, although his composition keeps well away from any troublesome detail in the figure of Iphis.

One artist who did show an interest in this story is John William Godward, whose own lifestyle demonstrated he wasn’t afraid to shock. Sadly, his two paintings of Ianthe dodge the issues, and are only weakly narrative in any case, although they’re still rather beautiful. Godward’s Ianthe (1889) above simply shows the bride-to-be, and I can see no hint of Ovid’s story.

His undated painting, again of Ianthe below is more elaborate, but I still cannot see any references to the issues or events.

There is another painting which, in recent years, had become associated with the story of Iphis and Ianthe, and on some websites has been re-titled to make it appear to be about this story.

This is Angelica Kauffmann’s The Artist in the Character of Design Listening to the Inspiration of Poetry (1782), which has been misinterpreted as showing a pre-transformed Iphis embracing Ianthe, as if in a lesbian relationship. As its real title demonstrates, that suggestion would be a travesty of Kauffmann’s intent. I also suspect that George Bowles, for whom she painted it, would have been shocked if someone had suggested that this was actually Iphis and Ianthe.

Perhaps Latin poetry can remain subtle enough for Ovid to get away with such a remarkable story so long ago, whereas the visual explicitness of a painting could never have enjoyed such licence. We could do with more brave paintings now, to challenge some of modern society’s remaining prejudices.

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.
