What, however, is missing from scholarship and publications is a collective study of the harbours and the anchorages used in the Byzantine Empire. Harbours and Anchorages of a Mediterranean Empire: edited by Johannes Preiser-Kapeller, Taxiarchis G. Kolias and Falko Daim, Mainz, Germany, Romisch-Germanisches Zentralmuseum, 2021, 264pp., illustrations, some colour, bilingual edition, £57.32 (hbk), ISBN 978-3795436773, Propylaeum, 2022 (ebk), ISBN 978-3969290859 New archaeological data on the operation of harbours are included in the following two papers: K. Manoussou-Ntella presents new evidence of the form of the Byzantine harbour of Rhodes, especially of its fortifications, and M. Papadimitriou gives a brief account of Late Antique finds from the harbour of Piraeus. [Extracted from the article]
