Book 8 of Ovid’s Metamorphoses resumes his account of King Minos of Crete waging war against the Greeks, and the hapless Cephalus who had inadvertently killed his wife Procris with his javelin. Cephalus and his party return to Athens, by which time King Minos is already laying waste to Megara, and attacking the city of Alcathous ruled by King Nisus. The latter has a lock of purple hair on his head, a talisman that ensures the safety of his kingdom.

Nisus’ daughter Scylla regularly watches the forces of Minos from her royal tower, and has got to know many of the Cretan commanders, including Minos himself. From her watching, she feels that she has fallen in love with him, and has an impulse to go to him to bring the fighting to an end, and to marry him. One night, she’s determined to act, so sneaks into her father’s bedroom, and cuts off his lock of purple hair to end the protection it had given his kingdom. She then makes her way out of the city, through the Cretan lines, until she meets King Minos. She tells him what she has done, and presents him with the lock of hair.

She’s shocked that, far from winning Minos’ love and hand in marriage, he calls on the gods to curse her, and refuses to let her enter Crete. Nevertheless, Minos conquers the city before setting sail once more in his ships. Scylla lets loose a long tirade of insults at Minos, and calls on her father Nisus to punish her for her treachery. With a final insulting reference to Minos’ wife Pasiphae and her mating with a bull, Scylla announces that she will cling to Minos’ ship and follow him over the sea. The gods had changed her father Nisus into an osprey, which then pursues Scylla, who is in turn transformed into a seabird, probably a shearwater.

Ovid then summarises the story of Minos and the Minotaur of Crete. He tells of Minos’ return, and his sacrifice of a hundred bulls to Jupiter. But he couldn’t escape the shame of his wife Pasiphae’s bestial adultery with a bull, resulting in the birth of the Minotaur, a beast with the head of a bull and the body of a man.

Gustave Moreau appears to have started to paint Pasiphaé in the 1880s but then to have abandoned it, probably because of difficulties it would raise in depicting her bestial relationship.

Minos had the architect and artificer Daedalus design and build a maze, within which the Minotaur was confined. Every nine years, the monster was fed on Athenian victims, but at the third such feeding, Minos’ daughter Ariadne helps Theseus kill the Minotaur.

This detail of a wonderful painted cassone The Legend of Crete from around 1500-25 shows what has become a popular image of the labyrinth constructed by Daedalus. At its centre, Theseus has just decapitated the Minotaur, while Ariadne waits, holding the thread enabling him to retrace his steps to the exit.

George Frederic Watts was apparently driven to paint The Minotaur (1885) as a response to a series of articles in the press revealing the industry of child prostitution in late Victorian Britain; those referred to the myth of the Minotaur, so early one morning he painted this image of human bestiality and lust. His Minotaur has crushed a small bird in its left hand, and gazes out to sea, awaiting the next shipment of young men and virgin women from Greece.

Earlier in his career, Gustave Moreau painted this scene of Athenians Being Delivered to the Minotaur (1855). Wearing laurel wreaths to mark their distinction and sacrifice, the young men and women hold back while Theseus crouches, waiting to do battle with the beast, seen at the right.

Henry Fuseli captured the dynamics of the situation, in his spirited mixed-media sketch of Ariadne Watching the Struggle of Theseus with the Minotaur (1815-20). Theseus appears almost skeletal as he tries to bring his dagger down to administer the fatal blow, and Ariadne looks like a wraith or spirit.

Theseus, Victor over the Minotaur (c 1791) is one of only three paintings by Charles-Édouard Chaise known to survive. With its crisp neo-classical style, it shows Theseus standing in triumph over the lifeless corpse of the Minotaur. He’s almost being mobbed by the young Athenian women whose lives he has spared. At the left, his thread rests on a wall by an urn, suggesting that the young woman by it may be Ariadne; she is being helped by a young man.

Ovid then races through the rest of the story, where Theseus abducts Ariadne and takes her to the island of Naxos, only to abandon her there. Ariadne meets the god Bacchus, who comforts and marries her. Finally, Theseus takes Ariadne’s wedding diadem and sets it in the heavens as the constellation Corona Borealis.
