When Peter Paul Rubens received the commission for the high altar of Antwerp Cathedral in 1620, the stakes could not have been higher: the city’s spiritual heart demanded a vision of the Virgin’s Assumption that would outshine all rivals. Before laying brush to the vast final canvas, Rubens drafted his ideas in a series of preparatory sketches, of which this Sketch for the Assumption of the Virgin is among the most revealing. These oil sketches—dynamic, fluid, and alive with energy—were a hallmark of Rubens’s process, allowing him to test compositions and lighting effects at speed.

The Antwerp commission would become one of the crowning achievements of his early career, and this sketch preserves the moment when inspiration first struck. The scene Rubens chose is the Virgin Mary’s ascent to heaven, body and soul, as witnessed by the astonished apostles. In this sketch, the Virgin is swept upward by a swirl of cherubs, her arms open in acceptance, while below, the apostles gesture in awe and disbelief. The tumbling clouds and radiant light focus all attention on Mary, whose blue robe and white garments signal her purity and heavenly favor.

The apostles’ varied reactions—some reaching upward, others shielding their eyes—capture the human response to divine mystery. Compared to Titian’s more restrained Assumption of the Virgin in Venice, Rubens’s version surges with movement and theatrical drama, a hallmark of the Baroque. Although the exact medium of this sketch is uncertain, Rubens’s oil sketches were highly prized by collectors even in his own lifetime, sometimes more so than the finished altarpieces. The final Assumption for Antwerp Cathedral remains in situ, but this preparatory work has traveled through private hands and collections, valued both as a glimpse into the artist’s working mind and as an artwork in its own right.

Today, it stands as a testament to Rubens’s restless creativity during a period when he was at the height of his powers, shaping the visual language of the Counter-Reformation. The sketch’s loose brushwork and bold composition continue to inspire admiration for the artist’s ability to capture both narrative and emotion in a single, swift gesture.
