No other face in Peter Paul Rubens’s life appears as often, or as tenderly, as that of Suzanne Fourment—his sister-in-law, and the younger sister of his second wife, Hélène. In Head of a woman (Suzanne Fourment), painted around 1650, Rubens returns to a familiar muse, whose features grace several of his most intimate works. The painting’s origins are shrouded in some uncertainty: while it is often believed to be a study for a larger composition, no definitive finished painting with this exact likeness survives.

This sense of mystery has only deepened its allure for scholars and visitors alike. Rubens chooses to capture Suzanne at a moment of gentle introspection. Her gaze is cast slightly downward, lips parted as if on the verge of speech or thought, while soft light grazes her cheek, illuminating the warmth of her skin. The artist’s loose, confident brushwork brings a sense of immediacy, as if he painted her from life, in a single sitting.

The absence of elaborate costume or background focuses our attention entirely on her expression and presence—an approach reminiscent of Rembrandt’s late portraits, where psychological depth outweighs narrative detail. Here, Rubens’s affection for his sitter is palpable, inviting us into a private world. The painting’s early history remains somewhat obscure, typical of many studio works and studies by Rubens in his later years. It likely remained in private hands for generations, admired as a personal keepsake rather than a public commission.

Over time, scholars have debated whether this is a preparatory study or an independent portrait, but consensus now favors its status as a work painted from life, possibly as a gift or for the artist’s own collection. Today, Head of a woman (Suzanne Fourment) stands as a testament to Rubens’s enduring fascination with the people closest to him, and to the quiet, searching humanity he could conjure with a few strokes of the brush.
