This monograph examines the complex landscape of Greek minor cults and heroic sagas across the Adriatic Sea. Moving beyond the heavily studied Diomedes tradition, the work focuses on lesser-known legendary cycles and religious practices, providing a comprehensive textual and epigraphic inventory. Through diachronic analysis and mythological stratigraphy, it identifies the successive historical actors—ranging from early Euboean and Corinthian navigators to Phocaeans, Athenians, and Syracusans—who introduced, adapted, or revitalized these religious paradigms. Rather than conforming to traditional colonial models, Greek interaction in the Adriatic region functioned predominantly through emporic and exploratory networks. By contextualizing minor cults—such as those of Aphrodite, Artemis, and various Homeric heroes—within nautical routes and maritime orientation networks, the research illuminates the vital role of the Adriatic periphery in the broader history of archaic and classical Greek expansion toward the West
