Alexander Shewan (1851- 1941) had worked for the Indian Civil Service but was better known as an Homeric scholar.
Leslie Shepard in his Introduction to a 1968 edition of Lewis Spence’s The Histoy of Atlantis notes that it used be fashionable to jeer at the existence of Atlantis but, as the Homeric scholar, Professor Alexander Shewan points out, “that can hardly continue, now that Mr. Lewis Spence has examined the evidence at length in The Problem of Atlantis, Atlantis in America, and The History of Atlantis.”
Gerald Massey (1828-1907) was an English poet and self-taught Egyptologist. One result of his studies was to identify the Egyptian god Horus with Jesus. On the subject of Atlantis, Massey claimed that sun-worshipping Atlanteans migrated to Egypt but failed to identify their place of origin. His huge work on ancient Egypt, Ancient Egypt: The Light of the World, is widely available.
