Portrait of Antoine de Bourbon (detail).

This portrait of Antoine de Bourbon, painted around 1548, depicts the father of the future King Henry IV—the first Bourbon monarch who would bring the dynasty to power in 1589. Corneille de Lyon's portraits of the Bourbon-Vendôme family document a lineage that would transform French history. His sitters are captured with a freshness and directness of observation that distinguished his intimate portraits from more formal court likenesses. Corneille de Lyon's distinctive small-format portraits on colored grounds—particularly his blue-green or red backgrounds that isolate the sitter's face with maximum clarity—established a formula that was widely imitated throughout 16th-century France.

The small-scale bust portrait captures the prince with characteristic precision and restraint. Fine brushwork defines costume details while maintaining focus on the sitter's alert expression.
