More than one voice
Delphi dominates modern accounts of Greek prophecy, but it was one of many places where Greeks sought answers from the gods. Some oracles were famous across the Mediterranean, others served a single valley or family. They differed in how they worked, who ran them and what questions they handled. Comparing them shows that the Delphic system, with its prophetess and formal replies, was only one way to arrange communication with the divine.
Dodona
Dodona, in Epirus in north-western Greece, is generally regarded as one of the oldest Greek oracles. It was a shrine of Zeus, with Dione worshipped alongside him in later periods. The Iliad already mentions it, describing priests called Selloi who slept on the ground and did not wash their feet. Ancient authors describe how the god’s will was read from the rustling of leaves in a sacred oak, and later sources add details such as the sound of bronze vessels and the flight of doves, though the exact methods are debated.
Dodona is valuable to historians because many small sheets of lead survive on which inquirers scratched their questions. They include private and practical matters such as whether to marry, whether a business would prosper or who was the father of a child. These are rare firsthand records, and they show how ordinary people used oracles, a perspective that Delphi’s literary record rarely gives. The site also has a theatre and council house from later centuries, which show it became a major regional sanctuary.
Trophonius at Lebadea
The oracle of Trophonius at Lebadea in Boeotia offered a very different experience. Pausanias, who says he consulted it himself, describes a long preparation. The inquirer stayed in a special building, bathed in a river, sacrificed animals, and drank from two springs called Lethe and Mnemosyne, forgetting and remembering. He was then taken to an underground chamber, where he was said to be pulled through a narrow opening and to receive visions or sounds. Afterwards the priests helped him recover and write down what he had seen.
The story was well known in antiquity, and the descent had a reputation for being frightening. Because our main account is a firsthand description by a traveller of the second century CE, it is useful but may be coloured by what priests chose to tell visitors. The ritual elements, including isolation, special drinks and darkness, fit what anthropologists call altered states, but the evidence does not allow certainty about what participants experienced.
Dream oracles and healing
Another family of sites relied on incubation, sleeping in a sanctuary in the hope of a dream. The oracle of Amphiaraus at Oropos was one, and the healing shrines of Asclepius at Epidaurus and elsewhere were others. Visitors slept in a designated building and later described the dream to priests. In the healing cults, the dream might include a cure, which is why Asclepian healing temples are discussed in the history of Greco-Roman medicine as well as religion.
Apollo’s other sites and the east
Apollo had several other oracles, including Didyma and Claros on the coast of Asia Minor. These became very active in the Hellenistic and Roman periods, when the area formed part of the Roman Asia province, and cities there sent embassies to consult them. Beyond Greece proper, some Greeks consulted the oracle of Zeus Ammon at the Siwa oasis in the Libyan desert. Alexander the Great is reported to have made a famous visit there in the early 330s BCE, though what was said is uncertain.
Methods beyond the shrine
Divination was not limited to oracles. Greek life included many forms of reading signs, and local experts, called manteis, handled them.
- Sacrifice. Seers examined the entrails of sacrificed animals, especially the liver, before battles and important decisions.
- Bird signs. The flight and cries of birds were read as omens. Homer’s characters often respond to such signs.
- Dreams. Dreams could be seen as messages, and professional interpreters explained them.
- Lots and chance sayings. Drawing lots was one method at several sanctuaries, and overheard words were sometimes taken as signs.
- Collections of oracles. Oracle-collectors, called chresmologoi, gathered and recited oracular verses, sometimes becoming influential in politics.
An army commander might consult a seer in the camp while the city sent a delegation to a distant shrine. These approaches belong to the larger landscape of myth and ritual, in which the same communal rites connected the gods to daily life.
Comparing the sites
Different oracles suited different needs. Delphi gave formal verse or prose answers to states and individuals, with a priesthood and a stable calendar. Dodona handled many everyday questions, often with simple yes or no replies. Trophonius offered a dramatic personal experience. The dream shrines promised healing or guidance. The Iliad plot summary alone shows how important divination was in the earliest Greek literature, and the continuing importance of these places shows that it stayed vital for a very long time.
What they shared was a belief that the gods communicated through certain people, places and signs, and that this communication needed careful handling. Details of individual sites remain uncertain in places, and ancient descriptions often come from outsiders who visited once, so the safest approach is to treat the broad patterns as well supported and the specifics as open to revision.
