This enigmatic and highly symbolic painting depicts Gabrielle d'Estrées, the celebrated mistress of King Henry IV of France, sitting in a bathtub alongside her sister, the Duchess of Villars. The sister's peculiar gesture of pinching Gabrielle's right nipple is widely interpreted by art historians as a coded allegorical announcement of Gabrielle's pregnancy with the king's illegitimate child (César de Vendôme). In her left hand, Gabrielle holds Henry IV's coronation ring, hinting at her unfulfilled aspiration to wed the monarch and become queen. In the background, a domestic servant is seen sewing baby linens, further reinforcing the thematic core of impending motherhood.
