Diogenes Laertius Vitae philosophorum 8.1.8

[8] Aristoxenus says that Pythagoras got most of his moral doctrines from the Delphic priestess Themistoclea. According to Ion of Chios in his Triagmi he ascribed some poems of his own making to Orpheus. ¹ They further attribute to him the Scopiads which begins thus: Sosicrates in his Successions of Philosophers says that, when Leon the tyrant of Phlius asked him who he was, he said, A philosopher, ² and that he compared life to the Great Games, where some went to compete for the prize and others went with wares to sell, but the best as spectators; for similarly, in life, some grow up with servile natures, greedy for fame and gain, but the philosopher seeks for truth. Thus much for this part of the subject.
