Guy Lachenaud’s Mythologies, religion et philosophie de l'histoire dans Herodote is a substantial scholarly study published in 1978 by the Université de Lille. Spanning 761 pages, the volume explores how Herodotus weaves myth, religious belief, and philosophical reflection into his narrative of the past. Lachenaud examines the historian’s treatment of divine intervention, customary practices, and underlying ideas about causality, showing that Herodotus’ work cannot be reduced to a simple chronicle of events. The book draws on a wide range of ancient sources and modern interpretations to argue that Herodotus’ historiography is deeply informed by the cultural and intellectual world of fifth‑century Greece. It remains a valuable resource for researchers interested in ancient historiography, the interplay of myth and history, and the methodological foundations of Herodotus’ Histories.
