In researching the cult of the gods of vegetation of the archaic and classical periods scholars can often find traces of Dionysiac and Bacchic elements in the cycle of Apollonian rituals.

Evidence was found on the Cycladic island of Naxos during the excavations supervised by Professor Lambrinoudakis. Architectural finds uncovered there date from the seventh and sixth century BC and were interpreted as belonging to the cult of Dionysus or Kore, one of the deities of the Eleusinian Mysteries. Similar evidence from Eretria (Euboea), this time, has been exhibited by the Swiss Archaeological School, under Dr. Pierre Durcey. The photographic and archival material on display led us through the history of ancient Eretria down to realization of the very origin of the Apollonian cult.
