In 1636, King Philip IV of Spain commissioned a cycle of mythological paintings from Peter Paul Rubens for his hunting lodge, the Torre de la Parada, near Madrid. Among the sketches Rubens prepared for this grand project is The Origin of the Milky Way, a vibrant and energetic study that captures a moment of divine chaos. The commission was remarkable for its scale and ambition: more than sixty works were planned, with Rubens overseeing a workshop of assistants and sending paintings from Antwerp to Spain.

This sketch stands as a testament to Rubens’s ability to condense myth and motion into a few sweeping brushstrokes. The scene bursts with the drama of ancient myth: the infant Heracles, brought by Hermes to the sleeping goddess Hera, suckles at her breast. Awakened, Hera recoils in surprise, and her spilled milk arcs across the sky, forming the Milky Way. Rubens chooses this explosive instant, filling the composition with swirling drapery, startled gods, and a cascade of white that leaps from Hera’s chest to the heavens.

The vigorous gestures and luminous flesh recall Rubens’s admiration for Titian, yet the tumult and theatricality are distinctly his own. The presence of Hermes, winged and watchful, signals the intervention of the gods in mortal fate. As a preparatory sketch, this work was never meant for public display, but rather as a guide for the larger painting destined for royal eyes. The finished version, executed by Rubens’s workshop under his direction, once adorned the Torre de la Parada, though many of these paintings were later dispersed or lost in the upheavals of the eighteenth century.

The sketch itself survived, offering insight into Rubens’s creative process at the height of his late career. Today, it is preserved as a prized example of the Baroque imagination at work, a window into both the mythic world and the bustling studios of seventeenth-century Antwerp.
