Cave of the Cumaean Sibyl
About
Workers cut this 131-meter gallery straight into the tufa flank of Cumae's acropolis, its trapezoidal cross-section engineered to survive the region's frequent earthquakes. Six openings pierced the rock along its length, throwing shafts of daylight across the floor as visitors walked toward a vaulted inner chamber. Legend held that a prophetess spoke Apollo's oracles here in a voice that echoed through a hundred mouths in the stone. Virgil sent his hero Aeneas down this same passage in the Aeneid, and a visitor in 117 CE could still walk its full length, even with the oracle's prophetic heyday long past.
What happened here
You come with a question, and the form of the question matters as much as the answer. There is a fee, a preliminary sacrifice, and a wait — sometimes days, sometimes only on certain days of the year. The consultation itself is controlled: the enquirer rarely meets the speaker directly, and the response arrives through an intermediary, in verse or in writing, and often ambiguously enough to survive being wrong. Cities consult about colonies, wars and plagues; individuals about marriage, illness, travel and lost property. The sanctuary grows rich on the gifts of those whose answers came out well. Sceptics are common and say so openly. By this century several famous oracles are quieter than they were, and people notice.
In ancient writing
