Plutarch's dialogue "On the daimonion of Socrates" is a unique combination of exciting historical romance and serious philosophical and religious discussion: A narrator from Boeotian Thebes tells his Athenian friend how Thebes was liberated from Spartan domination in a fateful night of midwinter 379/8 BC and connects this with the retelling of a fascinating philosophical discussion about the famous daimonion of Socrates in the afternoon and evening before. Besides presenting an introduction, a revised Greek text, and a new English translation (with copious notes), the volume offers a range of essays on themes providing further insights into this masterly literary piece: on the historical, religious and philosophical background and on thematic connections with other works by Plutarch.
