Underwater Archaeologists Discover Roman-Era Thalamagos Wreck
The European Institute for Underwater Archaeology and Egypt’s Ministry of Tourism and Antiquities discovered a thalamagos (Nile cabin boat) in Alexandria’s Royal Port during 2025 excavations, using high-resolution sonar and machine-learning wreck detection. The 28m, flat-bottomed wreck bears Greek graffiti and resembles the Palestrina mosaic depiction, suggesting local construction and Nile use. Post-excavation analysis is underway to determine its roles and links to the nearby Isis temple.
Key Points
- 1Identify thalamagos wreck using high-resolution sonar and machine-learning during 2025 Royal Port excavations
- 2Reveal local construction indicators: Greek graffiti and flat-bottom design point to Alexandrian-built, Nile-adapted vessel
- 3Imply broader port economy: cabin boats served ceremonial, passenger, and cargo roles in Roman Alexandria
Scoring Rationale
New archaeologically significant find and practical ML-survey use; limited industry-wide impact beyond maritime archaeology contexts.
