Each summer, the Culture Ministry-sponsored Hellenic Festival’s agenda at the Herod Atticus Theater is enriched by additional events organized by other agencies, that is if KAS, the Central Archaeological Council, gives them its blessing for use of the ancient venue. This summer, the Hellenic Festival’s additional activity will again feature over 30 productions, most of them during the month of August, when the state-sponsored festival’s activity takes a monthlong break. One of the highlights of these additional events will be the Teatro Di Roma’s production of «Memoirs of Hadrian,» a stage adaptation of French writer Marguerite Yourcenar’s novel. The presentation will be held as part of an exchange program established by Greece’s National Theater and the Italian theater, which is headed by the renowned actor and director Giorgio Albertazzi. Also included on the agenda of Herod Atticus extras are performances by the Belgrade Opera’s National Ballet, Cairo Opera’s National Ballet, the National Theater with a repeat of one of this winter season’s productions – either «Medea» or «Ion» – Spyros Evangelatos’s Amphitheater for its presentation of «Hecuba» with Anna Synodinou in the main role, the Aristophanes Theater Group with Thymios Karakatsanis as «The Good Soldier Schweik,» and the Patras Municipal Theater with «Electra,» with Karyofyllia Karabeti in the lead role.
