During that same year C. G. Naumann, the Leipsic publisher, began the issue of a definite edition of all his writings, in fifteen volumes, under the editorial direction of Frau Förster-Nietzsche, Dr. Fritz Koegel, Peter Gast and E. von der Hellen. In this edition his notes for "_Der Wille zur Macht_" and his early philological essays were included. The notes are of great interest to the serious student of Nietzsche, for they show how some of his ideas changed with the years and point out the probable structure of his final system, but the general reader will find them chaotic, and often incomprehensible. In October, 1888, but three months before his breakdown, he began a critical autobiography with the title of "_Ecce Homo_," and it was completed in three weeks. It is an extremely frank and entertaining book, with such chapter headings as "Why I am so Wise," "Why I Write Such Excellent Books" and "Why I am a Fatality." In it Nietzsche sets forth his private convictions regarding a great many things, from cooking to climates, and discusses each of his books in detail. "_Ecce Homo_" was not printed until 1908, when it appeared at Leipsic in a limited edition of 1250 copies. In January, 1889, at Turin, where he was living alone in very humble quarters, Nietzsche suddenly became hopelessly insane. His friends got news of it from his own hand. "I am Ferdinand de Lesseps," he wrote to Prof. Burckhardt of Basel. To Cosima Wagner: "Ariadne, I love you!" To Georg Brandes, the Danish critic, he sent a telegram signed "The Crucified." Franz Overbeck, an old Basel friend, at once set out for Turin, and there he found Nietzsche thumping the piano with his elbows and singing wild songs. Overbeck brought him back to Basel and he was confined in a private asylum, where his general health greatly improved and hopes were entertained of his recovery. But he never got well enough to be left alone, and so his old mother, with whom he had been on bad terms for years, took him back to Naumburg. When, in 1893, his sister Elizabeth returned from Paraguay, where her husband had died, he was well enough to meet her at the railroad station. Four years later, when their mother died, Elizabeth removed him to Weimar, where she bought a villa called "_Silberblick_" (Silver View) in the suburbs. This villa had a garden overlooking the hills and the lazy river Ilm, and a wide, sheltered veranda for the invalid's couch. There he would sit day after day, receiving old friends but saying little. His mind never became clear enough for him to resume work, or even to read. He had to grope for words, slowly and painfully, and he retained only a cloudy memory of his own books. His chief delight was in music and he was always glad when someone came who could play the piano for him.
