François I Invents Fontainebleau

After the Battle of Marignano in 1515, François I transforms Fontainebleau into laboratory of French Renaissance. Between 1528 and 1540, he has the Galerie François I erected, where Rosso Fiorentino and Primaticcio invent the School of Fontainebleau: Mannerism, extravagant stuccos, allegories mixing pagan mythology and royal emblems. The king installs works by Leonardo da Vinci there, including the Mona Lisa, which will remain at the château until its transfer to the Louvre. Fontainebleau doesn't imitate Italy: it digests it, adds the Fontainebleau forest, court festivities and a new idea of the palace as permanent workshop of European artists.

The medieval castle is profoundly remodeled by François I, who spends part of each autumn there to hunt in the surrounding forest. He brings artisans from Italy — Rosso from 1530, Primaticcio around 1532 — and entrusts them with entire spaces to decorate.

The Galerie François I, sixty-four meters long, combines frescoes, paneling and gilded stuccos. Rosso develops there a vocabulary of satyrs, nymphs and scrolled frames that will influence French decoration until Louis XIV's reign. The ceiling alternates sculpted coffers and allegorical scenes celebrating the king as protector of the arts.

Leonardo da Vinci arrives in France in 1516, invited by François I, and dies at Clos Lucé in 1519. The Mona Lisa appears in Fontainebleau's inventory in 1539; it remains there before entering the Parisian royal collection. This presence symbolizes the link between France's court and the Italian Renaissance.

Fontainebleau becomes the model for Loire châteaux and European palaces: Henri IV is born there; Napoleon abdicates there in 1814. The School of Fontainebleau marks the first national synthesis between late Gothic and nascent classicism — a style born from a hunting lodge become royal academy.
