There are manifold possibilities for the infernal machine unraveling beneath the streets or inhabiting entire planets — it could construct simulacra, infiltrate spaceships with insinuating metal tentacles, conduct experiments, terraform the soil, create new life, manipulate politicians, cause natural disasters — technology gone mad, endlessly proliferating… The dangers of technology, or technology in the hands of nefarious individuals is by far one of the most popular themes of science fiction. I cannot count how many Star Trek episodes, novels, movies, and other television shows examine these scenarios — innumerable, it goes without saying.
I’ve chosen a wonderful collection of science fiction cover art with replete with a variety of infernal machines: the fear inducing robot on the cover of The Stars Will Judge, the many-limbed man attacking contraption in Rendezvous on a Lost World, the towering mass of The Killing Machine, my personal favorite — the fantastic lumbering spider-legged mechanical contrivance on the cover of Farmer in the Sky, etc.
Enjoy!

So many of the science fiction machines look similar to microscopic bugs like demodex and dust mites.
Haha, yeah they do. I wouldn’t doubt that sci-fi artists used insects, mites, etc for inspiration.
More beautiful classic cover art, you know I love this stuff! Thanks for posting, and keep ’em coming. 😀
Thank you for the kind words!
Always love a good dose of cover art – and the process behind their creation is fascinating to watch. Plus, this selection’s a fine showing of classic sci-fi; the covers certainly reflect their decades’ style well, with the colorful dose of robotic fun.
Thanks for visiting! None of these novels (well, perhaps Heinlein’s Farmer in the Sky and Vance’s The Killing Machine) are considered “classics” exactly. But the artists are some of the best — I have covers here by the “big three”, Paul Lehr, Ed Emswiller, and Richard Powers.
My grandfather had a small collection of sci-fi paperbacks, among them the edition of The Killing Machine by Jack Vance that you have on display here. As a kid, I never did get around to reading most of those books, unfortunately, and after he passed away I’m not sure where they got off to. But my memory of that Vance book, with its sinister cover, did cause me years later to read a collected edition of The Demon Princes stories by Vance, which included that one. Interesting to see that old cover again after all these years, and to find out who the artist was. I’m unfamiliar with Richard Powers, but I’ll look through your blog archives to see if you have other examples of his work.
I have multiple posts devoted to solely his art. He’s one of the top three most famous sci-fi artists. A surrealist after my own heart….
Can I just say, again, how much I love your Science Fiction Cover Art series? There really is nothing else like it.
Thanks for your kind words — I really enjoy putting them together! I was inspired a while back by a now mostly defunct blog — http://cheapscifi.wordpress.com/
