Book excerpt: The most famous conspiracy of silence in the history of antiquity is examined here by one of the three archaeologists entrusted by the Archaeological Society of Athens with the final excavations of the Sanctuary. He traces the history of the cult in the archaeological remains, from the first traces of habitation at the site in the Middle Bronze Age (around 1900 B.C.) to its final grandeur and decay in Imperial Roman times. A guided tour of the Museum at Eleusis, illustrated with photographs of objects in the Museum, as well as air views, plans, and detailed photographs of the ruins closely correlated with the text, takes into account the needs of the visitor at the site as well as the reader at home. Originally published in 1961.
