Anna Komnene, Byzantine physician and scholar (died 1153)

Anna Komnene, commonly Latinized as Anna Comnena, was a Byzantine Greek historian. She is the author of the Alexiad, an account of the reign of her father, Byzantine emperor Alexios I Komnenos. Her work constitutes the most important primary source of Byzantine history of the late 11th and early 12th centuries, as well as of the early Crusades. Although she is best known as the author of the Alexiad, Anna played an important part in the politics of the time and attempted to depose her brother John II Komnenos as emperor in favour of her husband, Nikephoros Bryennios the Younger.
