This article aims at analysing the imaginary cycles and the regeneration of the Great Mythical Time in chosen works of Jules Verne (The Mysterious Island, The Eternal Adam). The analysis leads to a conclusion that in both these works the given theme plays an important role, whereas the appearance of the great cosmic cycles ending with spectacular catastrophes results in a readjustment of the images of the beginnings of the human civilisations (images of paradise, Atlantis, etc.). According to Verne, the end of one civilisation, or even our world, not only is an image of an irreversible apocalyptic disaster but also the beginning of a new civilisation.
