We can, however, say that the ancient Greeks had no written revealed texts akin to the Bible or the Qur’an. There were “mysteries” and initiations of various kinds that involved ecstatic states, perhaps not unlike the shamanic ones seen today in other parts of the world, and there were plenty of temples and shrines. It is true, as well, that even in the great Athenian age of reason and philosophy a man like Socrates could be executed for religious reasons.
