We've got the evil Professor Tode (who modifies an atom-smasher into a time machine that travels to the Palaeolithic and to Atlantis), a fatherly older professor, his beautiful young daughter (menaced by evil Tode), casually written racist pronouncements (by Rousseau), and our hero scientist, the dashing Jim Dent. But my favorite sentence was the brief description of quantum mechanics, which I didn’t expect in a 1930 science fiction tale.

In an underground city, Queen Phaestra uses a past-viewing machine of vague nature to show the destruction of Atlantis to two good-hearted men. But Atlantis itself is not visited, and there are no time phenomena apart from the viewing.

After the time mish-mash of Ijon Tichy’s seventh voyage, it wasn’t clear whether Ijon would ever ply the channels of time again, but here he is, traveling back in time to persuade himself to go forward in time and take up the helm of THEOHIPPIP—a.k.a. Teleotelechronistic-Historical Engineering to Optimize the Hyoerputerized Implementation of Paleological Programming and Interplanetary Planning. It takes a few attempts for older Ijon to convince younger Ijon to head to the future on a one-man chronocykl, but when he does, the younger Ijon begins the unexpectedly hard task of righting history’s wrongs. As a sophisticated time traveler yourself, you’ll spot what’s happening early on, while you also get a tour of history from the formamtion of the Solar System to the extinction of the dinosaurs and the paintings of Hieronymus Bosch. You’ll also recognize the fun Lem has at the expense of the bureaucracies of mid-20th-century Poland.
