Overview

The Yew Tree Ball, known in French as Le bal des if, was a lavish masked ball held in the Hall of Mirrors at the Palace of Versailles on the night of 25–26 February 1745. It forms a notable episode in the social history of the ancien régime both for its theatrical costume theme and for the personal consequence often associated with the event: the meeting between King Louis XV and Jeanne-Antoinette Poisson, who would later become the Marquise de Pompadour.

Setting and spectacle

The ball took place in one of Versailles’ grandest chambers, the Hall of Mirrors, with thousands of guests gathered in the adjoining Hercules Room and surrounding spaces. Contemporary accounts emphasize the scale and theatricality of the evening: vast crowds, glittering lights, music and elaborate masks. The recurring visual motif was garden topiary; the king and many courtiers appeared dressed and made up to resemble clipped ornamental trees.

Costumes and theme

Participants' disguises imitated garden vegetation. The king and several gentlemen of his court wore costumes evoking topiary forms fashioned to look like the yew—a popular evergreen used in formal French gardens. Such masquerades mixed playful anonymity with courtly display: masks allowed nobles to move outside ordinary protocol for an evening while the elaborate outfits reinforced rank, taste and the theatrics of royal leisure.

Meeting and immediate aftermath

Accounts credit the ball as the moment when the king came into close contact with Jeanne-Antoinette Poisson, whom he had first seen earlier that year. Contemporary reports vary in detail, but within months she was being introduced at court and, on 14 September 1745, was presented as the Marquise de Pompadour. She became the king’s acknowledged mistress and a leading patron of arts and letters until her death in 1764.

Significance and legacy

The Yew Tree Ball is remembered not only for its costume conceit but for its role in a broader pattern of court spectacle and social networking at Versailles. Masquerades and themed entertainments were occasions when social boundaries could be playfully tested and when personal connections might be formed or accelerated. In this case the evening helped to bring a woman to the king’s attention whose political, cultural and artistic patronage would mark much of the reign.
