Pythia is from the Greek Pythía — title of the iconic high priestess of the Temple of Apollo at Delphi. The Pythia (Oracle of Delphi) — high priestess of the Temple of Apollo at Delphi from roughly the 8th century BCE to the 4th century CE; the most-influential oracle in the ancient Mediterranean world for over 1,000 years; consulted by kings, generals, statesmen, and ordinary citizens; Greek poleis (city-states) made political decisions based on her prophecies; her cryptic responses shaped events of the Persian Wars, the Peloponnesian War, and the rise of Alexander the Great; the famous Delphic maxim "Know Thyself" (γνῶθι σεαυτόν) was inscribed at the entrance to her temple; Croesus, Alexander, and the Roman Emperor Hadrian all consulted her; her cult ended only with the rise of Christianity under Emperor Theodosius I (392 CE); Delphi remains a UNESCO World Heritage Site (1987). Pythia in literature — appears throughout Western literature from Aeschylus's Eumenides (458 BCE) to modern works including Mary Renault's The Bull from the Sea (1962) and Madeline Miller's Circe (2018) — the latter a New York Times bestseller with 1+ million copies sold. Pythia Peay — modern American writer.
Pythia does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Pythia reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
