Aline and Valcour

Aline et Valcour; ou, Le Roman philosophique is an epistolary novel by the Marquis de Sade. It contrasts a brutal African kingdom, Butua, with a South Pacific island paradise known as Tamoé and led by the philosopher-king Zamé.

Sade wrote the book while incarcerated in the Bastille in the 1780s. Published in 1795, it was the first of Sade's books published under his true name.
