There are architectural features and whole buildings, tools and machinery, tombs, works of art, musical instruments, trinkets, and much else besides. Drawings in Books in Medieval Britain from the Ninth Century to the Reformation approaches this material as both a class of artistic endeavour and of psychological symptom. Its main purpose is to investigate how medieval drawings in books may be defined, classified, and understood in relation to their physical settings and the purposes they were made to serve. Thus, the study has been designed to do something important that caters to the interests of both art historians and historians of the medieval book. Chapters 3 and 4 investigate drawings at the fronts and backs of books, and chapters 5 and 6, drawings embedded in margins and textual fields.
