I thank Professor Cristiano Casalini for the invitation to include this volume in the History of Early Modern Educational Thought (hemet) series that he edits. I also thank him for his dedication to bringing this volume into print. It has been a pleasure to work with him. I thank Tim Page for his careful and patient copyediting, which spared me from many mistakes. I thank Theo Joppe of Brill for guiding the manuscript into print. Other friends and colleagues who assisted on individual chapters are acknowledged and thanked in the chapters. I am grateful to all.
