Part 3 of this book, called ‘Voyage to Laputa . . . ‘ references a ‘floating island’ and also apparently describes two moons of Mars (Phobos and Deimos) which weren’t discovered officially until 150 years later. There are a number of other references to certain scientific information which apparently weren’t know at the time he wrote the book.
I thought it would be interesting for anyone wanting to research this a little more, as Ellen Lloyd has done. She believes that “Jonathan Swift possessed knowledge he should not have had in the 18th century… “Someone” must have given him the information and he wrote it down”.
The link to the article I read is here . . . . . . . Jonathan Swift’s Secret Knowledge And Extraordinary Interaction With UFOs – MessageToEagle.com and the link to the Wikipedia entry for Voyage to Laputa is here . . . . . . . Gulliver’s Travels – Wikipedia, the free encyclopedia.
I’ve never read Gulliver’s Travels, but I think I might just get hold of a copy now.
