The Danube in Greek Mythology: Between Geographical Knowledge and Mythical Imagination

This article examines the role of the Danube River, known to the ancient Greeks as the Ister (Istros), in Greek mythology and early geographical thought. Through a comparative, mythological, historical, and geographical analysis of primary sources including Hesiod, Herodotus, Apollonius Rhodius, Pindar, Strabo, and Diodorus Siculus, the study identifies three major mythological conceptions of the Danube: as a cosmic river linked to the Hyperborean tradition, as a river of mythic tragedy associated with the Phaethon cycle and the enigmatic Eridanus, and as a route of heroic exploration in the Argonautic narrative. The article demonstrates how the Danube occupied a unique liminal space in the Greek imagination, a boundary between the known and the unknown world, between geographical reality and mythological projection. The persistence of mythological motifs alongside increasingly rational geographical descriptions reveals the complex interplay between empirical knowledge and symbolic imagination in ancient Greek perceptions of the regions beyond the familiar Mediterranean world.
