When they ran off to France in the summer of 1814, Mary Godwin and Percy Shelley began a joint journal, which they published in 1817 under the title History of a Six Weeks' Tour, adding four letters, two by each of them, based on their visit to Geneva in 1816, along with Percy Shelley's poem Mont Blanc. The work celebrates youthful love and political idealism and consciously follows the example of Mary Wollstonecraft and others who had combined travelling with writing. The perspective of the History is philosophical and reformist rather than that of a conventional travelogue; in particular, it addresses the effects of politics and war on France. The letters the couple wrote on the second journey confront the great and extraordinary events of the final defeat of Napoleon at Waterloo after his Hundred Days return in 1815. They also explore the sublimity of Lake Geneva and Mont Blanc as well as the revolutionary legacy of the philosopher and novelist Jean-Jacques Rousseau.
