Schaeffer, Claude Frédérick-Armand
Claude Frédérick-Armand Schaeffer (1898-1982) was a French archaeologist who is probably best known for his work at the Ras Shamra site in Syria which he identified as the ancient port city of Ugarit. He worked on and wrote about the site from 1929 until his death.
Schaeffer enter the arena of catastrophism in 1948 when he declared that during the Bronze Age on at least five occasions widespread catastrophic destructions has taken place throughout the Middle East. He attributed these events to seismic activity,which was perhaps related to the ‘seismic storm’ referred to by Stavros Papamarinopoulos in his paper, Plato and the seismic catastrophe in the 12th century BC Athens(b).
Plato recorded how the priests of Sais told Solon of a succession of catastrophes that befell the region, including earthquakes, inundations such as the Flood of Deucalion and the fall of Phaeton adding historical support for the theories of Schaeffer, Velikovsky and Gallant inter alia.
Dale Drinnon has a worthwhile article(a) on Schaeffer and his relationship with Velikovsky.
