The aërial edifices, the crystalline palaces, which with their filmy vapours had so long hidden from him the actual world, seemed to detach themselves from earth and to float up as though drawn by an invisible force. They did not melt away, but swaying with a gentle movement rose in all their translucent glory to the high realms of pure Poetry. In the place which they had occupied, Shelley now saw the world as it is, the brown earth arduous to cultivate, the harsh faces of men, women full of nerves and hysteria, the cruel and obstructive society from which he longed to escape. The poem which occupied his thoughts the oftenest was the story of an ideal Revolution. He did not want the scenes of bloodshed which ruined for him the otherwise inspiring story of the French Revolution. He wanted his Revolution to be the work of a pair of lovers. His personal experience had taught him that only the love of a woman can inspire a sublime courage. Laon and Cythna, two ideal anarchists, were to be the transfigured portraits of himself and Mary. He would make them die at the stake, for their ideas, as he would have liked to die himself, exchanging a last kiss in the midst of the flames, a kiss so delicious that the agony would become a sort of voluptuous refinement of ecstasy. For him love did not attain its maximum unless he could associate it with thoughts and sufferings shared in common. Now that he and Mary, married and fairly well off, seemed about to begin an easier life, he desired to escape from this somewhat commonplace happiness, and to live in imagination the magnificent and perilous destiny which might have been his in other lands and other ages. He passed his time among the little islands of the Thames where the swans build their nests. Lying at the bottom of his boat completely hidden by the high grasses, he sought his inspiration in gazing up at the changing skies. The study of fleeting, interweaving colour and form had always given him immense pleasure, and every day he felt more strongly that his real mission in life was to seize the most transitory shades of beauty, and to fix them for ever in words buoyant and beautiful as themselves.
