History of a Six Weeks' Tour through a part of France, Switzerland, Germany, and Holland; with Letters Descriptive of a Sail Round the Lake of Geneva and of the Glaciers of Chamouni is a travel narrative by the British Romantic authors Mary Shelley and Percy Bysshe Shelley. Published in 1817, it describes two trips taken by Mary, Percy, and Mary s stepsister, Claire Clairmont: one across Europe in 1814, and one to Lake Geneva in 1816. Divided into three sections, the text consists of a journal, four letters, and Percy Shelley s poem "Mont Blanc". Apart from the poem, the text was primarily written and organised by Mary Shelley. In 1840 she revised the journal and the letters, republishing them in a collection of Percy Shelley's writings. Part of the new genre of the Romantic travel narrative, History of a Six Weeks' Tour exudes spontaneity and enthusiasm; the authors demonstrate their desire to develop a sense of taste and distinguish themselves from those around them
