By 1900, Europe’s female celebrities were les cocottes, Paris-based courtesans whose taste dictated fashion. Figures such as Mata Hari, la Belle Otéro and Cléo de Mérode were seen as ultimate Parisian women. But the work of these grandes horizontales was hardly all horizontal. They served as the trophy companions of powerful men, but also as hostesses and artistic muses. No place were these great beauties seen more frequently than at Maxim’s. The historic restaurant, once their showplace, celebrates the women’s rich lifestyle in its museum.
