Parmenides (514–469 BCE)
Born 514 BCE, died 469 BCE.
Parmenides of Elea (; Ancient Greek: Παρμενίδης ὁ Ἐλεάτης; fl. late sixth or early fifth century BC) was a pre-Socratic Greek philosopher from Elea in Magna Graecia (Southern Italy). Parmenides was born in the Greek colony of Elea to a wealthy and illustrious family. The exact date of his birth is not known with certainty; on the one hand, according to the doxographer Diogenes Laërtius, Parmenides flourished in the period immediately preceding 500 BC, which would place his year of birth around 540 BC; on the other hand, in the dialogue Parmenides Plato portrays him as visiting Athens at the age of 65, when Socrates was a young man, c. 450 BC, which, if true, suggests a potential year of birth of c. 515 BC. Parmenides is thought to have been in his prime (or "floruit") around 475 BC. The single known work by Parmenides is a philosophical poem in dactylic hexameter verse whose original title is unknown but which is often referred to as On Nature.
