In a curious and much-discussed passage in De insomniis, Aristotle claims that if a woman looks into a mirror during her menstrual period, her gaze will cause a blood-red stain to appear on the mirror’s surface. Modern commentators have struggled with the passage and its authenticity has been both questioned and defended. In the medieval Latin reception of Aristotle’s treatises on sleep and dreams, many of the commentators devote considerable attention to Aristotle’s account of the mirror phenomenon and try to harmonise it with his overall theory of perception as well as with his theory of motion. The paper analyses the development in a number of Latin commentaries on De insomniis from the twelfth and thirteenth centuries.

The trilogy Forms of Representation in the Aristotelian Tradition investigates how Aristotle and his ancient and medieval successors understood the relation between the external world and the human mind. It gives an equal footing to the three most influential linguistic traditions – Greek, Latin, and Arabic – and offers insightful interpretations of historical theories of perception, dreaming, and thinking. This final volume focuses on intellectual operations and analyses some of the most exciting issues pertaining to the conceptual representation of the external world. The contributions cover the historical traditions and their impact on contemporary philosophy of mind. 

The trilogy Forms of Representation in the Aristotelian Tradition investigates how Aristotle and his ancient and medieval successors understood the relation between the external world and the human mind. It gives an equal footing to the three most influential linguistic traditions – Greek, Latin, and Arabic – and offers insightful interpretations of historical theories of perception, dreaming, and thinking. This second volume focuses on dreaming and analyses some of the most prominent problems connected to dreams as representations. The contributions in this volume address the core Aristotelian texts and their reception, up to and including contemporary scientific discourse on dreaming. 

Aristotle’s De memoria et reminiscentia (‘On Memory and Recollection’) is the oldest surviving systematic study of the nature of human memory. Forming part of Aristotle’s other minor writings on psychology that were intended as a supplement to his De anima (‘On the Soul’) and known under the collective title Parva naturalia, Aristotle’s De memoria et reminiscentia gave rise to a vast number of commentaries in the Middle Ages. The present volume offers new knowledge on the ancient and medieval understanding of Aristotle’s theories on memory and recollection across the linguistic borders and philosophical traditions in the Byzantine Greek, Latin, and Arabic reception.
