When At the Theatre (La Première Sortie) first appeared at the second Impressionist exhibition in 1876, critics and the public alike were captivated by its daring focus: two young women, likely sisters, making their debut in Parisian society. The painting quickly became a talking point, not only for its fresh brushwork but for its subject—a moment of social ritual that was both intimate and public. The theatre box, a place to see and be seen, was a fitting stage for Pierre-Auguste Renoir’s exploration of modern life.

The sense of immediacy and observation in the work led one contemporary critic to remark on its "truth of sensation," a phrase that would echo through later discussions of Impressionism. The scene catches the sisters at the very moment of their "première sortie," their first formal outing into the world of adult society. Dressed in white, their faces lit by the golden glow of theatre lights, they peer over the balcony rail, eyes wide with curiosity and perhaps a hint of apprehension. The bouquet, gloves, and delicate fan are not just accessories but signals of their innocence and readiness for the social gaze.

Renoir’s loose, shimmering brushstrokes blur the boundaries between figure and background, suggesting the nervous energy of the evening. Unlike Edgar Degas’s backstage views of performers, Renoir places his subjects in the audience, turning the focus to the ritual of watching and being watched. As with many Impressionist works, the precise provenance of At the Theatre is not fully documented, but it is known that Renoir painted several variations on the theme of theatre boxes during the mid-1870s, reflecting both his fascination with Parisian leisure and his search for new patrons. The painting’s exhibition in 1876 helped solidify Renoir’s reputation as a chronicler of modern life, and today it is recognized as a key example of his early Impressionist style.

Now housed in the Museo del Prado, it offers visitors a glimpse into both the rituals of 19th-century Paris and the daring new vision of art that Renoir and his contemporaries were forging.
