These are the Hesperides, and they are the beautiful guardians of the tree that produced golden apples. That tree, according to Greek mythology, was a present the Earth gave to Hera when she married Zeus. Hera and Zues lived at the end of the World in a remote idyllic garden with Ladon, the snake. The Hesperides are singing him a lullaby in this beautiful painting by Frederic Lord Leighton, the leading artist of the classical revival, here represented in its late, very formal, stage.
Notice the long sinuous curves of the snake, the swan’s neck and the girls’ arms. They all follow the round shape of the painting. The image represents classical perfection and balance, which makes it all the more precious, because very soon Hercules is going to steal the apples from the tree and bring strife to the world. And it gets ugly between him and the snake.
I found this to be quite a story to go with such a captivating painting. I would bet that you do too. And the next time you are in Anthropologie, find the Hesperides ... it all fits.
