Source A: Herodotus 6.66. In about 491 BC the Spartans were unsure whether King Demaratus was really the son of the previous king, Ariston, and agreed to ask the oracle at Delphi. Demaratus' rival, King Cleomenes, wanted him removed.
'Cleomenes won over Kobon son of Aristophantos, the most powerful man at Delphi, and Kobon persuaded the prophetess Perialla to say what Cleomenes wanted said. So when the envoys put their question, the Pythia ruled that Demaratus was not Ariston's son. Later, however, all this became known: Kobon fled from Delphi, and Perialla the prophetess was removed from her office.'
To what extent did priestesses such as the Pythia have real power and influence? Use Source A as a starting point and your own knowledge.
Model answer
Source A shows how much the Pythia's words could matter: her ruling that Demaratus was not Ariston's son led to the removal of a Spartan king. Because Greeks believed the Pythia spoke for Apollo, cities and individuals consulted her on war, colonies and laws; the Athenians received the famous 'wooden walls' oracle before Salamis, and the Pythia chose the names of Cleisthenes' ten tribal heroes. Other priestesses also held real authority. The priestess of Athena Polias, from the Eteoboutadai, held office for life, and Herodotus tells how she ordered the Spartan king Cleomenes out of Athena's sanctuary as if he were any stranger; before Salamis she announced that the sacred snake had not eaten its honey-cake, which helped persuade Athenians to leave the city.
However, this influence had clear limits. It was religious, not political: no priestess could vote, speak in the Assembly or hold a magistracy. At Delphi, male priests interpreted the Pythia's words and put them into verse, and Plutarch says she was chosen precisely because she had no learning or skill, so she was valued as a passive vessel for the god rather than for her own judgement. Source A shows how vulnerable she was: a powerful man, Kobon, persuaded Perialla to give the answer Cleomenes wanted, and when this was discovered she was removed from office, while the real power lay with the men behind the bribe.
Overall, priestesses had real influence, because their words and actions were believed to come from the gods and could change the decisions of cities and kings. But it was influence rather than power: it depended on religious belief, worked within a system run by men, and could be manipulated, as the case of Perialla shows.
Explanation
High-level answers use Source A both ways: as evidence that the Pythia's words could topple a king, and as evidence that men could manipulate and remove her. They widen the discussion to other priestesses and distinguish religious authority from political power. Description of how the oracle worked, without judgement, stays in Level 2.
