The Cult
The Acheron's cult was a cult of the dead: an oracle of the dead, the Nekromanteion, stood above its Thesprotian bank at Ephyra — the “oracle of the dead on the river Acheron” where Herodotus (5.92) sends Periander in the sixth century BCE. Excavated by Sotirios Dakaris from 1958, the Hellenistic sanctuary, with an earlier Archaic phase, centres on a hall set over dark underground corridors and chambers where consultants, on the usual reconstruction, descended after purification and incubated through the night awaiting the dead. The landscape itself was the instrument: the river's cold springs plunge into the gorge, and the Acherusian lake, where Plato says the souls gather, has silted to marsh. The oracle's interpretation has been honestly debated; what is not debatable is that for centuries the living came here, as to one fixed address, to speak with the dead.
