What can the architecture of ancient ships tell us about their capacity to carry cargo or to navigate certain trade routes? How do such insights inform our knowledge of the ancient economies that depended on maritime trade across the Mediterranean? These and similar questions lie behind Sailing from Polis to Empire , a fascinating insight into the practicalities of trading by boat in the ancient world. Allying modern scientific knowledge with Hellenistic sources, this interdisciplinary collection brings together experts in various fields of ship archaeology to shed new light on the role played by ships and sailing in the exchange networks of the Mediterranean. Covering all parts of the Eastern Mediterranean, these outstanding contributions delve into a broad array of data - literary, epigraphical, papyrological, iconographic and archaeological - to understand the trade routes that connected the economies of individual cities and kingdoms.
