Convergenze plurilingui. Incroci e convivenze linguistiche tra Medioevo e prima età moderna.

From the publisher:

The concepts of "plurilinguism" and "multilingualism" are normally used in studies dealing with current linguistic realities observed in communities of speakers. This volume collects eleven essays which apply these categories to historical settings, spanning a period from the Middle Ages until the late Renaissance. It demonstrates that contacts between languages have, for centuries, characterized and shaped the linguistic realities of Europe.
