A sanctuary more than a city
Delphi is usually called a city, but it is better understood as a sanctuary with a small settlement attached. It sits on a steep slope of Mount Parnassus in central Greece, above the Pleistos valley and within sight of the Gulf of Corinth. Unlike Athens or Thebes, it never grew into a major independent power. Its importance came from Apollo’s shrine and the oracle that spoke there, which people from across the Greek-speaking world and beyond treated as an authority.
The site was used well before the classical period, and there are Mycenaean-era remains nearby. Greek tradition said the place first belonged to the earth goddess Gaia and was guarded by a serpent, Python, before Apollo took it over. Historians generally think the cult of Apollo became important there from around the eighth century BCE, and that the sanctuary’s fame grew along with Greek colonisation and trade in the following centuries.
The layout of the sanctuary
Visitors approached along the Sacred Way, a zigzag path climbing the slope toward the Temple of Apollo. It was lined with statues, monuments and small buildings paid for by cities and individuals. Many commemorated military victories, sometimes over other Greeks, so the road also worked as a display of rivalry and prestige.
Some of the main features were:
- The Temple of Apollo. Ancient writers describe several earlier temples, including one that burned in the sixth century BCE and was rebuilt with help from Athenian aristocratic families, according to Herodotus. An earthquake damaged its successor in the fourth century BCE, and the Doric columns and foundations visible today largely belong to the rebuilding that followed. It is a good example of Greek temple architecture adapted to a cramped, sloping site.
- The treasuries. Cities built small, richly decorated buildings to hold offerings. The best known are the Siphnian Treasury, dated to about 525 BCE and financed, according to Herodotus, by the island’s mines, and the Athenian Treasury, often linked to the period after the battle of Marathon, though the exact date is debated.
- The theatre and stadium. Above the temple, the theatre looks out over the valley. The stadium higher up hosted the athletic events of the games.
- The Castalian Spring and the lower sanctuary. Visitors purified themselves at the spring. Farther down the road, the sanctuary of Athena Pronaia contains the round building known as the Tholos, whose purpose is still discussed.
Also associated with the site was the omphalos, a carved stone regarded as the navel of the world. In the myth, Zeus released two eagles from opposite ends of the earth and they met at Delphi.
The Pythian Games
Delphi also hosted one of the four great festivals of the Greek world. The Pythian Games were held every four years in honour of Apollo, and the traditional date of their reorganisation is 582 BCE, following a conflict over control of the sanctuary often called the First Sacred War. At first the main contest was musical, a hymn to Apollo sung with a lyre, and athletic and chariot events were added later.
The prize was a wreath of laurel, the plant sacred to Apollo. Together with the Olympic Games and two other festivals held at Isthmia and Nemea, the Pythian Games formed a circuit that gave Greeks a shared calendar of competition. A sacred truce let visitors travel safely to the festival, though such truces were not always respected.
A pan-Greek meeting place
Delphi was governed with the help of an association of neighbouring peoples known as the Amphictyony, which looked after the sanctuary. That arrangement gave states a way to work together on a religious matter even when they disagreed elsewhere. Its limits were clear: the sanctuary was involved in several disputes called Sacred Wars, the best known of which, in the mid-fourth century BCE, ended with Philip II of Macedon gaining influence over the council.
Cities used the sanctuary to publish decisions, set up monuments and consult the oracle before important steps such as founding a colony. Delphi gave quarrelling states a neutral stage. The Persian threat of the early fifth century BCE tested that role, since the Greco-Persian conflict forced the sanctuary to take a position, and later writers argued about whether it had been too cautious.
The sanctuary also had a hand in shaping civic culture. Athens, for example, is said to have asked the oracle to choose the eponymous heroes of its new tribes when Cleisthenes reorganised the citizen body, a step that fed into Athenian democracy. Tradition claimed that Delphi sanctioned the laws of Sparta, though the historical details of that story are uncertain.
The maxims
Delphi is also remembered for short sayings. According to the traveller Pausanias, who wrote in the second century CE, inscriptions in the temple forecourt included “Know thyself” and “Nothing in excess”. Greek authors often credited such sayings to the Seven Sages, and the Delphic version made them a shared moral vocabulary. Philosophers returned to them again and again. “Nothing in excess” is often compared with later ideas such as the doctrine of the mean, though the connection is one of general theme rather than direct borrowing.
Wealth, plunder and decline
Offerings built up in the sanctuary for centuries: bronze statues, gold and silver dedications, tripods and war booty. One famous surviving bronze is the Charioteer, usually dated to the 470s BCE, which was found in the nineteenth century. Such wealth attracted unwelcome attention. The sanctuary was seized during the Sacred Wars, and under Roman rule, after Roman expansion into Greece, commanders and later emperors removed treasures. Even so, writers such as Plutarch, who served as a priest at Delphi around the turn of the second century CE, show that it still had real prestige in the Roman period.
The oracle’s influence faded as the old cults lost support in the late Roman world, and the sanctuary is generally considered to have closed by the end of the fourth century CE. Earthquakes, landslides and later building covered much of it. A village called Kastri grew over the ruins until the French School at Athens, beginning in the 1890s, relocated it and began large-scale excavation. Today Delphi is a protected archaeological site with a museum.
What to take from it
Delphi shows how a religious site could become an international institution without being a state. Its monuments, games and sayings served several purposes at once: worship, competition, diplomacy and shared identity. Much of what we know comes from writers like Herodotus, Plutarch and Pausanias, who wrote with their own aims and sometimes long after the events, so details are best treated with some caution.
