Plutarch of Chaeronea and Delphi
He was a priest of the Delphic Sanctuary for many years. He wrote several works in which we find testimony about the Oracle, such as “Why Pythia is not giving prognoses in rhyme anymore” and “About the delphic ‘Epsilon’“.
He also talks about the position of upper class women in religion and society: He was a friend of his contemporary Arhiis, the woman leading the dionysiac dance in honour of Dionysus in Mount Parnassus. This particular individual could, acccording to Plutarch, discuss issues of religious syncretism [about Greek Dionysus and Egyptian Ossiris].
Plutarch mentions a rather interesting story about Pythia’s answer to a young priest who, after being seduced by a young girl, asked if there was a way to achieve a forgiveness.
Pythia answered: “God is not prohibiting what he was not able to prevent from happening“.
