  • S5 Ep6: Prayer or Pleasure: Discovery of a 1st century AD barge in Alexandria, Egypt
    Feb 12 2026
    Renowned French maritime archaeologist Franck Goddio joins Professor Lucy Blue to discuss his latest discovery in the eastern harbour of Alexandria, Egypt. Working with his team of the European Institute for Underwater Archaeology (IEASM) in collaboration with the Egyptian Ministry of Tourism and Antiquities, Goddio reveals the uncovering of a 1st-century AD pleasure barge, known as a thalamegos. A bathymetric sub-bottom profiler survey detected a long anomaly and careful excavation through the sediment revealed the vessel’s planking, keel, and structural elements. Measuring over 30 metres long, this flat-bottomed boat was located in the small royal harbour off the island of Antirhodos.

    Limited finds and graffiti inscribed above the keel, helped date the vessel. These clues, combined with the writings of the Greek geographer Strabo, who described Alexandria during the Roman period, offer insights into the luxurious activities that may have taken place on board. An alternative hypothesis links the barge to the Temple of Isis, originally situated near the palace of Cleopatra VII, raising the intriguing possibility that it was used in Isiac ceremonial processions. As Goddio explains, it is hardly surprising that the harbours of Alexandria continue to yield extraordinary discoveries, as after all, this was once the very centre of the ancient world.

  • S5 Ep5: The Nissia Shipwreck: An Entangled Biography
    Jan 7 2026

    Dr. Stella Demesticha, Associate Professor of Maritime Archaeological Research at the University of Cyprus, joins Professor Lucy Blue to discuss a remarkable Ottoman-period shipwreck located off Cyprus’ east coast. Excavated over three seasons by the Maritime Archaeological Research Laboratory of the University of Cyprus in collaboration with the Cyprus Department of Antiquities, the wreck identified as the Nissia, is a post-medieval vessel likely dating to the 18th–19th century AD.

    Measuring over 30 metres in length, the wreck represents a significant addition to our understanding of Cyprus’ maritime history during the Ottoman era. Although no definitive cargo has yet been recovered, intriguing material clues are emerging. Timber analysis reveals that its oak planks originate from northern Europe, suggesting a possible Dutch connection. Four cannons have also been recorded on the site, though evidence of looting raises the possibility that additional armaments were once present.

    Other finds include Ottoman smoking pipes, bricks, and bundles of pointed wooden logs believed to be firewood, offering valuable insight into life on board. As on-going research and scientific analysis continue, archaeologists anticipate that further discoveries will clarify the identity, origins, and final voyage of this vessel.

  • S5 Ep4: Crushed: The Truth Behind Endurance
    Nov 27 2025
    Professor of Solid Mechanics Dr Jukka Tuhkuri, from Aalto University’s Department of Mechanical Engineering, joins Professor Lucy Blue to uncover the real story behind Ernest Shackleton’s legendary ship, Endurance. While on board the Endurance22 Expedition vessel searching for the wreck, Dr Tuhkuri was collecting ice cores for his own research when he became intrigued by the theories around the crushing of the ship by ice. Studying the original ship’s plans, archival material, and applying his cutting-edge ice mechanics research, Dr Tuhkuri reveals surprising new insights into the ship’s design weaknesses, flaws Shackleton himself recognised, yet believed were worth the risk. The discussion explores how the ship’s structure, the ice conditions in the Weddell Sea, and the loss of the rudder combined to seal its fate on 21 November 1915.
