Bacchus-Dionysus, seen by A. Solomos in the mosaic of the church in Dafni, is depicted as an allegorical guide to the 'hidden theatre'. In the essay, the author presents the scientific and poetic work by the author of Saint Bacchus on unknown epochs in the Greek theatre from 300 BC to 1600 AD. In contrast to the West, which separates antiquity from the modern era, the East cultivates the continuum and development of the theatre. The Greek-Christian drama acts as a bridge linking the two epochs.
