<p><strong>Abstract.</strong> As a quick and effective way to archive the different stages of an excavation - notably to prepare the post-excavation phase and to document the production methods – photogrammetry has become an indispensable tool. Indeed, it offers a valid scientific model, usable by any member of the team and at any moment, without the need to return to the excavation site. Photogrammetry can also complement other archaeological tools such as manual surveys. The interaction between the complementary approach of the interpretative drawing measurements (IDM) and the photogrammetric model measurements (PMM) enables us to apprehend the error rate of the interpretative measurements <i>in situ</i>. It appears thus that the measurements taken flat have an error rate inferior to 2% whereas the distances that are either too long or taken on a three-dimensional support have an error rate that can exceed 10%. The input of photogrammetry is therefore an added value whether it be during the excavation phase or during the post-excavation studies.</p>

This book represents a significant contribution to the fields of Hellenistic archaeology, Hellenistic economy, naval architecture and shipping in the eastern Mediterranean. It asks (and answers) questions that are often simply assumed and not systematically investigated. — Dr. Conor Trainor, University of Warwick 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. Unique in its interdisciplinary approach and focus on the Hellenistic period, this collection digs into the questions that others don’t think to ask, and comes up with (sometimes surprising) answers. It will be of value to researchers in the fields of naval architecture, Classical and Hellenistic history, social history and ancient geography, and to all those with an interest in the ancient world or the seafaring life.

The book has been edited by Emmanuel Nantet and improved by further contributions, with sincere thanks to the contribution of the French Institute in Cyprus, of the CRESEM (Centre de Recherche sur les Sociétés et les Environnements Méditerranéens-EA 7397) and the LabEx Archimède (Archéologie et Histoire de la Méditerranée et de l'Égypte Anciennes). This book has benefited greatly from the advice of Conor Trainor (University of Warwick) and Christoph Schäfer (University of Trier). It has been copy-edited and proofread by Sharon Elisheva Turkington, Ivana Kubalova and Lucy Barnes.

This article focuses on the size of tonnage as an impact on the size of wooden components in a ship. It is based on a list of 66 tonnages, elaborated via a methodology employing three methods to deter mine tonnage (reconstruction of the hull lines, the tonnage formula, and the weight of the cargo). This list notes the thickness of the planking and of the moulded side of the frames. However, the article also explores further factors that are involved, particularly the evo lution of the architectural type. KeywordsFrame, hull line reconstruction, planking, tonnage RésuméCet article traite de l'influence du tonnage sur la taille des élé ments architecturaux en bois d'un navire. Il repose sur une liste de 66 tonnages, élaborée au moyen d'une méthode employant trois procédés pour déterminer le tonnage (restitution graphique des lignes de coque, formule de jauge et poids de la cargaison). Cette liste note l'épaisseur du bordé et la hauteur des membrures. Cependant, l'article évoque également d'autres facteurs tels que l'évolution des types architecturaux.
