Dr Hackett discovered in the Angelica Library in Rome a manuscript containing a unique text of the first constitution of Cambridge University. The centrepiece of this book is a critical edition of the text with an English translation on facing pages. The importance of his discovery for historians of Cambridge and of medieval university education cannot be overestimated. The Cambridge constitutions form a complete code, promulgated at a remarkably early date (c. 1250). Dr Hackett shows that Oxford lagged more than 50 years behind Cambridge in codifying its statutes and neither Paris nor Bologna, the oldest of all universities, had a written constitution or code of laws at this time.
