Honor Frost (1917-2010) was an early pioneer in the field of underwater archaeology. Early in her career, she worked in Byblos, Sidon, and Tyre, where she conducted ground-breaking research on ancient ports, harbours, and anchors under the auspices of the Institut Français d’Archéologie in Beirut. During the 1970’s, in collaboration with the Sicilian authorities and the British School at Rome, Honor directed the excavation and recovery of a Punic shipwreck, dated to the 3rd Century BC. Claire Calcagno is a maritime archaeologist with an interest in the archaeology of the ancient Central Mediterranean region and maritime exchange systems. She has conducted fieldwork at coastal and shipwreck sites around the Mediterranean and the Red Sea, and taught at universities in the U.K. and the U.S. As an independent scholar following her post-doc at M.I.T. she has oriented her research to the historiography of maritime archaeology, and the influence of technology on the evolution of the discipline. Her work as an academic translator ranges from books on biblical archaeology to medieval Venetian manuscripts. Claire holds degrees from Harvard University (A.B. in art history) and the University of Oxford (M.St. & D.Phil. in maritime archaeology). Elena Flavia Castagnino Berlinghieri holds a PhD in Maritime Archaeology from the University of Bristol (UK). She conducts scientific research in the field of archaeology, with a particular focus on underwater cultural heritage, conducting both terrestrial and underwater excavations and investigations. Her research areas include ancient harbour cities, shipwrecks, coastal settlement dynamics, sea-level changes, and the study of human interaction with coastal landscapes, with a special focus on the central Mediterranean. She is involved in the protection of underwater cultural heritage within the framework of the 2001 UNESCO Convention.
