Phoebus and Boreas, 1879
Phoebus, God of the Sun, and Boreas, God of the North Wind, made a bet about which of them could get a traveller to remove his cloak. The cold wind made the man pull his clothes more tightly around him but the rays of the sun had the opposite effect.
Moreau shows Boreas retreating beneath the hooves of Phoebus’s horse, the clouds pushed aside by the Sun God’s advance.
