Aristocles was wrestling material, and he needed a nickname. "With shoulders so broad ("platys" in Ancient Greek)," — Ariston the wrestling teacher must have said something like this — "you should be called 'Platon'!"
So, the story goes, Plato of Athens, son of Ariston and Petone or Perictione, got his name. As it is with things such as these, Diogenes Laertius also recounts two alternative etymologies, of course.
