Pierre Carnac (1921-2008) was the pen name of Professor Doru Todericiu, a Romanian who has written extensively on prehistory. He retired to Normandy in France where he continued writing until his death. He has tackled subjects such as Vikings and Templars in America, early Pacific migration as well as ancient science and symbolism. In 1971 Carnac explored the Bimini Stones with Dimitri Rebikoff and concluded that they were remnants of Plato’s lost civilisation. He published a book on Bimini in 1973. However, three decades were to pass before he had published another work, also in French, L’Atlantide, Autopsie d’un Mythe, dealing exclusively with Atlantis. In it he invokes the Egyptian Book of the Dead to demonstrate that a meteorite impact in the Atlantic destroyed Atlantis, echoing the work of Otto Muck. The attached map by Carnac shows his preferred location for Atlantis.
Joseph Bosco (?- 1931), according to David Hatcher Childress, was an archaeologist, who identified Malta as the location of Atlantis in 1922. He seems to have been greatly influenced by the research of Giorgio Grongnet de Vasse
Bosco lived in Constantine, then a city in French Algeria. He contributed frequently(a) to the local archaeological society, Societé Archaeologique du Departement de Constantine, from 1911 until 1927.
The Spanish writer Javier Sierra also refers to Bosco but is probably just quoting the earlier work by Childress. Pierre Carnac, in chapter six of his L’Atlantide, Autopsie d’un Mythe similarly refers to Bosco as a supporter of the Maltese location. Deloux and Guillaud in their French A–Z guide to Atlantis note Gozo as Bosco’s more specific choice. Gennaro d’Amato, the Italian writer also referred to Bosco in his 1930 book on Atlantis.
