Carlini trireme with 28 oars

Galley showing 28 oars copied by Capt. Carlini from the graffito of the House of Dionysos on Delos Island in 1930-33. If each sketched oar represents 3 levels of one oarsman, then this ship is a trireme with 170 oarsmen (Musée de la Marine, Paris).

Graffiti de Délos

By Arthur DE GRAAUW

I am a French/Dutch coastal engineer with extensive experience in the Mediterranean area. I compiled a list of ancient ports and harbours with latitude/longitude positioning, based on ancient and modern authors. My catalogue of ancient coastal settlements, ports and harbours contains nearly 6,000 sites.
My interest grew to ancient port structures like quays and breakwaters including harbour silting-up, ancient ships and navigation, ancient maps and units of measure, ancient climate including sea level rise, waves, earthquakes and tsunamis.
