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 English 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. The romantic elements of the work would have hinted at the text's radical politics to nineteenth-century readers. However, the text's frank discussion of politics, including positive references to the French Revolution and praise of Enlightenment philosopher Jean-Jacques Rousseau, was unusual for a travel narrative at the time, particularly one authored primarily by a woman. Although it sold poorly, History of a Six Weeks' Tour received favourable reviews. In proposing another travel narrative to her publisher in 1843, Mary Shelley claimed "my 6 weeks tour brought me many compliments"
