The object of this study is the performances of the troupe during the period 2004-2016, which include： （1） the eight different versions of the dramatic idyll Golfo, written in 1894 by Spyridon Peresiadis; （2） the three different versions of the tragedy Erofili, written in Crete in 1595 by Georgios Hortatzis, and （3） the three different versions of the ancient Greek tragedy Euripides＇ Orestes written in 408 B.C. The research shows how these performances bring the young audience closer to the Greek theatre, tradition and identity, and at the same time they lead the audience＇s thought to current issues. It also explores how Kakalas brings the past closer to us to the present time, combining the poetic fifteen-syllable verse, the theatrical codes of the Greek ＂bouloukia＂ （the wandering troupes who used to play at squares in the nineteenth century）, the technique of narration, parody and shadow theatre with postmodern style, manga masks, video projections and anime.展开更多
