In reality, the heritage of these Carnivals come from much older traditions, related to the pagan history in Europe and still preserved in its authentic form in Bulgaria and parts of Northern Greece – what corresponds to Ancient European Thrace. The tradition of representing the lifecycle of conception ¬– birth – death – rebirth, embodied in the Dionysian mysteries, rites and cult celebrations, gave birth to the tragedy theater plays in the Hellenistic world. The mysteries evolved into theater plays for the public in the Greek city-states, leaving a significant body of literary work. In Thrace, following the non-literary Orphic tradition, they have been preserved throughout the centuries in the form of popular festivities under the name of Kukeri.
