Note:
Consulting the Oracle. No one knows for certain how the process of consulting the Delphic oracle worked. However, over the years, a traditional account has been widely accepted. According to this description, a visitor who wanted to submit a question to the oracle would first make an appropriate offering and sacrifice a goat. Then a priestess known as the Pythia would take the visitor’s question into the inner part of Apollo’s temple, which contained the omphalos and a golden statue of Apollo. Seated on a three-legged stool, the priestess would fall into a trance.
Anyone could approach the oracle, whether king, public official or private citizen. At first, a person could consult the oracle only once a year, but this restriction was later changed to once a month.
