It is also an important source of information on the Byzantine war with the Normans, and the First Crusade, in which Alexius participated. While the Byzantines were allied to the Crusaders, they were none the less critical of their behaviour and Anna's book offers a startlingly different perspective from that of Western historians. Her character sketches are shrewd and forthright - from the Norman invader Robert Guiscard ('nourished by mainfold Evil') and his son Bohemond ('like a streaking thunderbolt') to Pope Gregory VII ('unworthy of a high priest'). The Alexiad is a vivid and dramatic narrative, which reveals as much about the character of its intelligent and dynamic author as it does about the fascinating period through which she lived.E.R.A. Sewter's translation captures all the strength and immediacy of the original and is complemented by an introduction that examines Anna's life and times. This edition also includes maps, appendices, genealogical tables, a bibliography and indexes of events and names.
