In nineteenth-century Paris, the pampered demimonde became almost indistinguishable from the haut monde, with mythical reputations growing up around its most alluring and favored celebrities. Grandes Horizantales examines the lives of four of the era's best-known courtesans-Marie Duplessis, La Présidente, La Païva, and Cora Pearl-and the men who were their lovers, providing a provocative look into the parlors and boudoirs of the women whose lives became legends.
