The first sketches for "The Will to Power" were made in 1884, soon after the publication of the first three parts of "Thus Spake Zarathustra," and thereafter, for four years, Nietzsche piled up notes. They were written at all the places he visited on his endless travels in search of health--at Nice, at Venice, at Sils-Maria in the Engadine (for long his favourite resort), at Cannobio, at Zuerich, at Genoa, at Chur, at Leipzig. Several times his work was interrupted by other books, first by "Beyond Good and Evil," then by "The Genealogy of Morals" (written in twenty days), then by his Wagner pamphlets. Almost as often he changed his plan. Once he decided to expand "The Will to Power" to ten volumes, with "An Attempt at a New Interpretation of the World" as a general sub-title. Again he adopted the sub-title of "An Interpretation of All That Happens." Finally, he hit upon "An Attempt at a Transvaluation of All Values," and went back to four volumes, though with a number of changes in their arrangement. In September, 1888, he began actual work upon the first volume, and before the end of the month it was completed. The Summer had been one of almost hysterical creative activity. Since the middle of June he had written two other small books, "The Case of Wagner" and "The Twilight of the Idols," and before the end of the year he was destined to write "Ecce Homo." Some time during December his health began to fail rapidly, and soon after the New Year he was helpless. Thereafter he wrote no more.
