When did masks begin to be used in greek theatre?

The use of masks in ancient Greek theater draw their origin from the ancient Dionysian cult. Thespis was the first writer, who used a mask. The members of the chorus wore masks, usually similar to each other but completely different from the leading actors. Picture 1 portrays a sort of mask suitable for the chorus.
