In Boreas and Oreithyia, the viewer sees a dramatic scene filled with swirling colors and dynamic figures. Boreas, the god of the north wind, is depicted with flowing robes and a powerful stance. Oreithyia, the personification of the cold north wind, appears ethereal and graceful.

The background features a turbulent sky, enhancing the emotional intensity of the moment. The painting is executed in oil on canvas, showcasing De Morgan's skill in blending colors and creating depth. The figures are rendered with meticulous attention to detail, highlighting the flowing fabrics and the natural forms of the characters. The use of light and shadow adds a three-dimensional quality to the composition.

The overall effect is one of movement, as if the scene is alive with energy. Evelyn De Morgan was a prominent member of the Pre-Raphaelite movement, known for her focus on mythological and spiritual themes. Boreas and Oreithyia reflects her interest in the interplay between nature and emotion.
