What religion is practiced in Greece?
If you are talking about thousands of years ago, it would be the ancient Greeks and their polytheistic pantheon of Gods. You might recognize them by their Greek names or the Roman names they were later given, such as Zeus (Jupiter), Aphrodite (Venus), Hades (Pluto), and Apollo. Today, though, Greeks are about 97 percent Greek Orthodox (though a number of Catholics, Jews, Muslims, and even modern adherents to the classical Greek mythology above exist under the freedom of religion the country enjoys).
