This monograph presents three previously unedited thirteenth-century treatises on hawking. The treatises clearly demonstrate the connections of the Anglo-Norman language with aristrocratic culture. They indicate its status as a worthy vehicle of knowledge beside Latin, from which the texts are derived. The treatises, which deal with nurture, training, and medical treatments, present an interesting repository of specialist technical vocabulary and make a valuable contribution to historical lexicology. The volume provides a full introduction and, in addition, the previously unedited Latin text of Phisica avium.
