Laws (version 2) by Plato (Πλάτων) (c. 428 BCE - c. 347 BCE)

Laws (Greek: Νόμοι) is Plato's last and longest dialogue. It is generally agreed that Plato wrote this dialogue as an older man, having failed in his effort in Syracuse on the island of Sicily to guide a tyrant's rule, instead having been thrown in prison. - Summary by Wikipedia
