In "Medusa (or on the eve of a lost world)” as well as in his serie "Natives", "M" tells us about ephemerality (of the human race, about life in general) suggesting remnants of an ancient and remote civilization extinct and lost, perhaps inhabitants of a "Lovecraftian" macrocosm of outer space or could be the representation of a microcosm, the depths of the magnified interior of the human being, molecules, bacteria, microbes, neurons ?... snippets of life in the final, what, even though it accompanies us throughout our lives, is actually so alien to us.
