Nietzsche, as is well known, devoted much time when a student at Leipzig to the study of three Greek philosophers, Theognis, Diogenes Laertius, and Democritus. This study first bore fruit in the case of a paper, Zur Geschichte der Theognideischen Spruchsammlung, which was subsequently published by the most influential journal of classical philology in Germany. Later, however, it enabled Nietzsche to enter for the prize offered by the University of Leipzig for an essay, De fontibus Diogenis Laertii. He was successful in gaining the prize, and the treatise was afterwards published in the Rheinisches Museum, and is still quoted as an authority. It is to this essay, written when he was twenty-three years of age, that he here refers.—TR.

In the latter years of his life, Nietzsche practically made Italy his home.—TR.
