Sir Humphrey Gilbert (1539-1583) was an English noble and Member of Parliament, soldier and explorer. He was the half-brother of Sir Walter Raleigh and was knighted for his colonisation work in Ireland.
In 1583, he claimed territory in Newfoundland for the English crown and in doing so laid the foundation for the overseas British Empire.
He theorised that America was Atlantis, which was partially submerged allowing the creation of the Northwest Passage. His views were expressed in his 1566 Discourse of a Discoverie for a new passage to Cataia(China) , which was not published until 1576. However, the archaic spelling in it make it a difficult read.
Hans Rudolf Stahel is possibly Swiss(a) and an architect by profession, he is also the author of a guide to Atlantis entitled Atlantis Illustrated, with a foreword by Isaac Asimov. While Stahel has located Atlantis in the Atlantic, Asimov opted for the destruction of Thera as the inspiration for Plato’s story.
The illustrations are good, but unfortunately are only in black and white. Stahel based all the designs and plans of Atlantis on Plato’s descriptions. His drawings, more than anything else, demonstrate the improbability of dimensions recorded by Plato. The consistent degree of over-engineering forces us to question the accuracy of Plato’s numbers and consider whether this perceived exaggeration is the result of an erroneous transcription of numerals or a misunderstanding of the units of measurement employed.
Stahel depicted Atlantis as an island, centred on the Azores with a chain of islands stretching from there to Newfoundland more or less in a straight line. He also envisages an Atlantean Empire stretching from parts of the west coast of America to include the Mississippi, Missouri and Ohio river basins, Central America and as far south as the Amazon basin. East of the capital he includes all of coastal Europe and the Mediterranean (except Greece), along the coast of north and west Africa, the Middle East and on into India. Imaginative if nothing else.
*The only other book attributed to H.R. Stahel is Die Pfahlbauer – Entstehung und Geschichte eines Pfahlbaudorfes, which deals with ancient European pile-dwellings that are comparable with the numerous crannogs of Ireland(b) .
