"The sanctuary of Athena Pronaia is located to the southeast of the sanctuary of Apollo. The sanctuary, or Marmaria, was visible to those arriving from the east, before arriving at the sanctuary of Apollo, hence the name Athena Pronaia, which means 'Athena in front of the temple'. The importance of the sanctuary was highlighted by a practice in which those who came to petition the oracle were first required to offer a sacrifice at the Athena Pronaia, who was the guardian of the Pythia."
