“When Multipliandre had risen up, by means of his wings, to 32,000 feet above the world’s surface, there was no more breathable air. It was impossible to make provision for that; there was only one course of action to take and he took it. That was discorporation. He flew over the highest peak in the entire world and left his body on the inaccessible point of a crag, after having wrapped it up well in furs, having treated it with a health-preserving gel, with which he filled the stomach, the mouth and all the bodily apertures and having placed it so securely that the winds and tempests could not dislodge it. Then, his detached soul could go wherever it wished, because, no longer being in the sphere of corporate life but that of souls, he could dispense entirely with entry into a body.”

Nicolas Edme Restif de La Bretonne, 1802
