post and comment. I overlooked Poul Anderson's own Martian invasion novel (see here) with its overtly Wellsian title and its plot twist of extrasolar aliens covertly controlling both Martians and Terrestrials. Thus, the list of Wells-Stapledon-Anderson parallels becomes:
interplanetary invasions in general;
Martian invasions of Earth in particular.
Wells' Martians attack Earth, then Venus. Stapledon's Terrestrials invade Venus, then Neptune. Also:
ERB's Moon Men conquer Earth and his Jovians plan to invade Mars;
Heinlein and the collaborative team of Niven and Pournelle each have a novel about an alien invasion of Earth.
Can anything more be said about this idea? We might think not until an sf writer proves us wrong.
When I said that Wells, Stapledon and Anderson wrote about the past, I mentioned Anderson's Time Patrol series but not his other historical fiction. It might be thought inappropriate to classify Wells' The Outline Of History alongside works of fiction. However, to write history and to write historical fiction are two ways to address history. Anderson's several volumes of historical fiction impart knowledge and analysis of periods and events. When I read about the Scipios at the Battle of Ticinus in a Latin text at school, I had already read about this event in Poul Anderson's "Delenda Est."
