Why were masks used in greek theatre?

Masks were originally used in Greek theatre to help the audience separate the identity of the actor from the identity of the character. With the masks on, the actors were no longer themselves, but the characters they were portraying.

that is because lower interest rates allowed people to work harder to make money. it multiplied like that and now the uno(not the game) is very strong.
