Continuing with our study of ancient Greece, we learned that many words related to drama and theater such as chorus & scenery originated in ancient Greece.
"All the actors were male, and they all played multiple roles, so a mask was used to show the change in character or mood. Masks challenged the actors to portray their characters' feelings in more subtle ways, with voice and body language, since they couldn't use facial expressions. The two masks are now used as the symbol for theater, in memory of its origins in ancient Greece. "
