Alexiad Of The Princess Anna Comnena [PDF ebook] 

First published in 2005. This is one of the fundamental sources of information on Chivalry as well as on many other interesting subjects. Princess Anna was the daughter of the Byzantine Emperor Alexius I, and obviously a highly educated and cultured woman. This is the first and only full translation of this remarkable work, although it has been much quoted in various scholarly works. Sir Walter Scott relied heavily on it for his various accounts of the chivalric tradition.
