|wketx=[[Ptoion]] or [[Ptoön]] (Ancient Greek Ptōïon [[Πτώϊον]], also Ptōon [[Πτῷον]] / [[Πτῶον]], Modern Greek Ptoo [[Πτώο]] or Oros Pelagias Όρος Πελαγίας) is a mountain chain in northeastern Boiotia. It stretches from Akraiphia by the former Lake Copais in the west to the Gulf of Euboea in the east, reaching up to 725 m (Agia Pelagia) in the west and 781 m (Petalás) in the east. The massif is particularly famed for the oracle of Apollo which was located in it in antiquity and was among the most important Greek oracles up to the time of the Persian Wars.
