It all began with Eris, the Greek goddess of discord and the original bad fairy at the christening – or in this case, at the wedding, showing up at the nuptials of Thetis and Peleus to make everyone simultaneously regret not inviting her and remember exactly why they didn’t by riling up the three most powerful goddesses in the Pantheon and starting one of the most famous wars in myth and legend. She brought with her a golden apple (never ever trust a golden apple) with an inscription on it reading ‘for the fairest’. Zeus, who might be all kinds of terrible but was smart enough to realise that was a mess he wanted no part of, hastily foisted the role of judge onto Prince Paris of Troy. Thanks to an ominous prophecy made at his birth, Paris was living as an anonymous shepherd at the time, in ignorance of his birthright. All that was about to change.
The three goddesses who felt the strongest right to the apple were Hera, Zeus’s wife and sister and queen of the gods; Athena, goddess of wisdom and war; and Aphrodite, the goddess of love. Each offered Paris an appropriately extravagant bribe depending on her governance. Hera promised power and riches, Athena assured him of good fortune in battle, but Aphrodite swore that he would have the most beautiful woman in the world as his own and Paris awarded her the apple – thereby making himself two implacable enemies, and an ally as fickle as she was powerful.
