The objective of the “Project of Electronic Documentation of the Ancient Theatre”, carried out under the auspices of the Institute of Mediterranean Studies of the Foundation of Research and Technology, is to compile in a data base every possible information about the ancient drama as a theatrical practice and cultural activity in the broader geographical boundaries of the Greek-speaking world. The research starts from the origin of the theatre in the 6th century B.C. Athens and terminates to the Late Antiquity and Early Byzantium, when theatrical competitions and official drama performances had ceased to be staged, especially after the prevalence of the Christian religion, but the activities of mimes, pantomimes and other forms of “paratheatre” were continuing to be performed.
