However, this was not so among such Greek scholars as Spyridon Marinatos (1901–1974), the excavator of ancient Thera (modern Santorini), which was buried in a volcanic eruption around 1638 B.C. Marinatos argued that Delphi’s active geological history made it difficult to know what changes might have occurred over the past two millennia. He also made a report on an anemotrypa (wind hole) in the modern town of Delphi—a small cleft in the rock that emitted gas with a sulfurous smell. Scholars outside Greece ignored these ideas.
