How have masks been used in ancient theatre?

In ancient theatre, particularly in Greek and Roman performances, masks were essential for conveying character and emotion. They allowed actors to portray multiple roles and enabled greater expression of emotions, as exaggerated facial features enhanced visibility from a distance. Masks also served a practical purpose, helping to amplify the actor's voice and create a larger-than-life presence on stage. Additionally, they helped maintain anonymity and allowed male actors to portray female characters, reflecting the social norms of the time.
