Plato, one of the most famous ancient philosophers, lived in Athens, Greece from 427 BC to 347 BC. He lends his name to the word “platonic,” however, Plato was probably not his real name, but was merely a nickname. “Plato” meant “broad,” possibly in allusion to his wide shoulders or forehead, or to the wide scope of learning he possessed. His real name may have been Aristocles, but this has not been officially ascertained.
