An interesting part of the Statute of 1254 relates to the length of time to be given to the various books, or groups of books, prescribed.  The entire Old Logic is to be read in about six months (October 1-March 25); the New Logic and Priscian’s Grammar in the same length of time; the Physics, the Metaphysics and On Animals, together, in somewhat more than eight months (October 1-June 25); the four books of the Ethics, alone, in six weeks; On Life and Death is to be completed in one week, and several of the other treatises in the same group are to be read in periods varying from two to five weeks.  Knowledge of these facts renders the list as a whole considerably less imposing than it might otherwise appear.
