Eleanor of Aquitaine (1122-1204) has been long noted for her political and cultural achievements that profoundly shaped twelfth-century Europe. Culturally, beyond her role as wife of kings Louis VII of France and Henry II of England and mother of kings Richard and John, she inspired the huge diffusion of the Arthurian cycle and the Celtic myths underpinning it. Without Eleanor, figures such as Merlin, Arthur and Guinevere (for whom Eleanor served as model) would never have assumed the enormous symbolic value they now possess. Politically, she embodied divine power that ended the dark age of patriarchy, playing a crucial role not only in the development of the Plantagenet Empire, but, also, in the granting of charters to merchants and craftsmen that led to the birth of the modern middle class. But her greatest influence, still shaping modern sensibilities, was her role as the symbol of courtly love, which was not a mere diversion of the aristocracy but a process of male initiation and transcendence that bears a close resemblance to Indian Tantra. While the Virgin Mary was restoring a feminine face to mediaeval religious life, Eleanor embodied the adulterous queen who incarnates sovereignty - the woman who shares authority with the men who act in her name, but only after that power has been transmitted to them through an initiatory process leading to sexual union.
