The papers collected in this volume deal mainly with ancient Greek or Roman philosophy. They range chronologically from the 5th century BC to the 6th century AD, and in them the evidence is fully presented and discussed. They are concerned mainly with the Presocratics, Plato, Aristotle, the Early Academy, the Platonic and Aristotelian traditions, especially as represented by Neoplatonism. In addition, there are a few more general articles. The first deals with the saying "Amicus Plato sed magis amica veritas" and studies the different forms of this proverb from the time of Plato and Aristotle to Cervantes in the 17th century. Another one discusses the rather complex transmission of Plato's alleged epitaph. A third one deals in detail with an incomplete but interesting allegorical interpretation of Heliodorus' Aethiopica.
