Village festivals and processions in honor of Dionysus (See also: Dionysia) amongst the ancient Greeks, are believed to be the origin of theatre, and therefore theatre costume. The sculpture and vase paintings provide the clearest evidence of this costume. Because of their ritualized style of theatre many masks were used giving each character a specific look and they varied depending if they were used for comedic or dramatic purposes. Some masks were constructed with a cheerful as well as a serious side on the same face in an attempt to indicate a change in emotion without a change of mask. The same is true for the Romans, who continued the mask tradition, which made the doubling of roles easier.
