Charles Joseph deGrave (1731/6-1805) was born in Ursel, which was then in the Netherlands and subsequently became a part of Belgium, which was only created in 1830. DeGrave held a number of government positions including a period as a member of the Council of Flanders. He dedicated the last years of his life to studying and writing. In 1806 his book on Atlantis and lost continents was published posthumously and was generally accepted as bizarre. This book, published in three volumes, is now available online *.
Nevertheless, this work was recently on sale on the Internet for €2,000, as most of the 800 copies of the first edition were apparently lost at sea.
Among his strange contentions were that Atlantis had been located in Netherlands/Belgium and that both Hesiod and Homer had been from that region. Another of his unorthodox views was that the Underworld visited by Odysseus had been islands at the mouth of the river Rhine.
Another Belgian writer, Hubert Lampo (1920-2006), devoted one of his books, Toen Herakles spitte en Kirke spon , to deGrave and his unusual Atlantis theories.
