A study in light and form, this abstract work by František Kupka explores the perception of reflections through rhythmic colour and layered brushwork.

František Kupka, a pioneer of abstract art, produced this work during a period of intense experimentation in Paris. The painting reflects his transition from representational subjects towards the exploration of pure colour and rhythmic form. In this composition, the oval shape acts as a frame for a series of overlapping, semi-transparent planes that suggest the presence of a figure or an object reflected within a glass surface. The application of paint is deliberate, with visible brushwork that builds the surface texture. Kupka employs a palette dominated by greens, yellows, and violet tones, which interact to create a sense of internal light. Rather than documenting a physical reality, the artist focuses on the sensation of sight itself. The curved lines and layered forms suggest a movement away from the static nature of traditional portraiture, moving instead towards the musicality of colour that defined his later Orphist period. Kupka often drew inspiration from scientific concepts, including the study of optics and the movement of light. This work demonstrates his interest in how the human eye perceives reflections and the distortion of space. By breaking down the subject into simplified, rhythmic shapes, he invites the viewer to engage with the painting as a visual experience rather than a narrative one. The work remains a clear example of his early twentieth-century approach to abstraction, where the boundaries between the subject and the surrounding space become fluid and interconnected. The signature in the lower left corner confirms the artist's hand during this formative time in his career, when he was actively moving towards the non-objective art that would define his later reputation.
