From the Internet: Eleanor of Aquitaine (French: Aliénor dAquitaine; Éléonore de Guyenne; 1122 or 1124 1 April 1204) was one of the wealthiest and most powerful women in western Europe during the High Middle Ages, a member of the Ramnufid dynasty of rulers in southwestern France. She became Duchess of Aquitaine in her own right while she was still a child, then later queen consort of France (11371152) and England (11541189). She was the patron of literary figures such as Wace, Benoît de Sainte-Maure, and Bernart de Ventadorn.
