It has been a long time ago since Professor De Rijk first drew our
attention to an important Parisian manuscript containing two treatises
on logic, both connected with the School of the Montani. The
school was established in the twelfth century on the Mont Sainte
Geneviève (which is situated in what is nowadays known as the Quartier
Latin). It was dominated by master Alberic (Albericus) of Paris. The Montani
were the heirs (faithful or not) of Pierre Abelard, Robert of Melun and
this master Alberic. The present work aims to provide a first working
edition of one of the treatises in the manuscript, the Introductiones
Montane maiores. This introductory work on logic contains a wealth
of information about the way in which logic was taught and practiced in
the schools of Paris of the twelfth century. It also gives insight into
the vicissitudes of the teachings of different Parisian masters. The
edition is preceded by an extensive introduction, with information about
the origins and contents of the text and discussions of some interesting
doctrinal elements.
