The book is a translation with introduction and commentary of the Platonic dialogue Hipparchus. Based on the excursus, which has given the dialog its name and bestows him a special position within the Platonic oeuvre, a comparative analysis of the tradition concerning the tyrant Hipparchus, his erection of herms with epigrams in Attica and his murder by Harmodios and Aristogeiton will show that the excursus and the dialogue have the numerous references to the entire work of Plato with regard to the topics of education, wisdom, friendship, love and deception.
