The Amphiareion at Oropos

Sleeping for an answer

The Amphiareion at Oropos was an oracle, a place where people asked a god for answers. It was also a place of healing. It belonged to Amphiaraus, a hero who was worshipped there as a god. A visitor who came with a question received the answer in a dream, by sleeping inside the sacred ground.

The visit followed set steps. First the visitor was purified, a ritual cleansing. Then they made sacrifices to Amphiaraus and to the other powers named at the sanctuary. The last animal offered was a ram. Its skin was spread on the ground, and the visitor lay down on it to sleep and wait for a dream.

The ancient writer Pausanias describes this practice at Oropos in the second century AD. He gives no priest’s reading of a dream and records no particular dream. He sets down the order of events: cleansing, sacrifice, sleep and the hope of an answer. The answer came in the dream. The preparation took place in a public sanctuary, with an altar, a spring and buildings anyone could see.

Why Amphiaraus answered at Oropos

In the account told at Oropos, the place began with a disappearance. Amphiaraus is fleeing from Thebes when the earth swallows him. The people of Oropos said their spring was the place where he rose again as a god. Pausanias notes that Amphiaraus was first treated as a god at Oropos, and that his fame then spread through the Greek world.

That local claim explains why water, sleep and the returned hero meet on the same ground. Amphiaraus is not a ghost who wanders. He has a fixed place where he came up from the earth, and the sanctuary stands around it.

Pausanias also records a custom of thanks. Anyone who had been healed by an oracle of Amphiaraus threw silver or gold into the spring. The people of Oropos treated the water as the place where he rose as a god.

The altar of five parts

The altar was divided into five shares, each for a different group. The first belonged to Heracles, Zeus and Apollo the Healer. The second belonged to heroes and their wives. The third was for Hestia, Hermes, Amphiaraus and the children of Amphilochus. The fourth was for Aphrodite, Panacea, Iaso, Hygieia and Athena the Healer. The fifth belonged to the nymphs, minor goddesses of nature, to the god Pan and to the rivers Achelous and Cephisus.

The list makes the oracle larger than one sleeper and one god. Apollo the Healer and the daughters of Asclepius, Panacea, Iaso and Hygieia, set healing beside the answering of questions. Hestia and Hermes stand with Amphiaraus himself. Rivers and nymphs bring the nearby water into the ritual.

Pausanias records the five shares, but he does not give a separate action for each one. So the altar should not be read as a full order of service that the source never gives.

What could be seen beside the dream

The sanctuary was more than a place to sleep. Pausanias saw statues of Amphiaraus, Amphilochus and other figures from the story of Thebes. Near the temple stood a theatre, and he describes its seats as white marble. These public buildings surrounded the private experience of each visitor.

Today the excavated ground is the archaeological site of the Amphiareion at Oropos. It lies in Attica, the land around Athens, but the ancient rite took place at Oropos and not in modern Athens.

What a sleeper saw in a dream is lost, unless another ancient writer chose to record it. Pausanias leaves something more exact: what people did before sleep, and what they left after a cure. A ram skin held the living visitor. The spring received metal from those who believed Amphiaraus had answered.
