At the bottom of a lake in Switzerland, Julien Pfyffer and his team of underwater archeologists have been studying the mystery of a Roman-era shipwreck cargo that was found—with no accompanying ship.
In March, Pfyffer and his organization, the Octopus Foundation, spent a month diving alongside partnering researchers in Lake Neuchâtel, in Western Switzerland. They measured and marked 19 new square-shaped sections four meters in size at an excavation site with an estimated 1,000 ancient objects strewn across the lakebed.
