This book is the first volume to appear in print since 1999 in Die Fragmente der Griechischen Historiker Continued, which continues Felix Jacoby’s monumental but uncompleted collection of fragmentary Greek historiography. It is part of section IV B (History of Literature, Music, Art and Culture) and provides a critical edition, translation and commentary of the fragments of Dikaiarchos, a pupil of Aristotle from late fourth century BCE. Dikaiarchos wrote about cultural history, literature, philosophers, politics, geography, ethics and the soul. The book advances the state of the art by presenting a new text and demarcation of the fragments, a study of the method of the authors citing Dikaiarchos, new readings and interpretations of the fragments and a reassessment of Dikaiarchos’ value as a historian.
