Paul Dijstelberge of the Special Collections Amsterdam has created a fantastic (if not quite complete) anatomical alphabet from initial caps drawn which pepper William Cowper’s 1724 book Myotomia Reformata: or an Anatomical Treatise on the Muscles of the Human Body.
William Cowper’s Myotomia Reformata via Morbid Anatomy. More info on the work itself available at The New York Academy of Medicine.
