A wide range of specialists provide a comprehensive overview of the reception of Pythagorean ideas in the Middle Ages and the Renaissance, shedding new light especially on the understudied ‘Medieval Pythagoras’ of the Latin West. They also explore the survival of Pythagoreanism in the Arabic, Jewish, and Persian cultures, thus adopting a multicultural perspective. Their common concern is to detect the sources of this reception, and to follow their circulation in diverse linguistic areas.
