Franck Goddio, a pioneer of modern maritime archaeology, points out features on a stone Sphinx made between 360-343 B.C. and recovered from the lost Mediterranean port city of Thonis-Heracleion, on display at the Saint Louis Art Museum in St. Louis on March 22, 2018. In 1992, Goddio discovered the ancient Great Port of Alexandria and in 2000, a team comprised of archaeologists, Egyptologists, historians, geologists, geophysicists and computer engineers discovered the submerged ancient city of Thonis-Heracleion and parts of the city of Canopus under 30 feet of water and four miles off today's Egyptian coast. The largest collection of Egyptian art ever shown outside of Egypt, nearly 250 pieces, will be on display until Sept. 9.
