Which term did the Greeks use towards those who did not speak Greek and follow classical Greek customs?

Mongo, Conan was not a real person

What is Tragic is the Germans called everyone Else Salvages for a excuse to rob and murder Millons of others

Interesting. I thought for decades it had something to do with long hair and beards and that the term “barber” derived from the same root word

Also, barbarians could not participate in Mystery rites even if they'd become a Greek citizen.
