HERODOTUS, ARISTOTLE, AND SOUNDING WEIGHTS: THE DEEP SEA AS A FRONTIER IN THE CLASSICAL WORLD
The ancient Mediterranean cultures knew far more about the deep sea than is generally realized. Pharaohs, emperors, scientists, fishermen, ships’ captains and sponge divers were all personally concerned with the topography and environment of the sea floor. Comments by the scientist-philosophers Aristotle and Posidonius indicate that by the early Hellenistic period, many areas of the Mediterranean Sea had been accurately measured down to 2000 m. This was an impressive accomplishment given the materials and technology available at the time. Both the difficulty of the undertaking and the apparently comprehensive scope of the inquiry reveal a profound and, so far, underrated interest in the deep sea among Greek and Roman intellectuals. In a richly illustrated talk, Prof. Oleson presents the surprising results of his research concerning ocean science and navigation in the ancient Mediterranean.
