In Fillettes devant la vague, we see two young girls standing by the waves. The colors are soft and muted, with shades of blue and white dominating the scene. The girls are dressed in light clothing, their figures contrasting against the dark, rolling waves.

The setting evokes a sense of calmness and innocence by the sea. The painting is characterized by Spilliaert's unique use of color and light. The brushwork is fluid, creating a sense of movement in the waves. The composition draws the viewer's eye towards the girls, emphasizing their connection to the natural world.

This piece showcases Spilliaert's skill in capturing the atmosphere of the seaside. Léon Spilliaert was a Belgian painter known for his Symbolist style and focus on themes of solitude and introspection. Fillettes devant la vague reflects his fascination with the sea and childhood innocence. An interesting fact about this work is that it embodies Spilliaert's exploration of light and shadow, which became a hallmark of his later pieces.

This painting is a beautiful example of his early work, showcasing his developing style.
