In Greek mythology, Pandion I (/pænˈdaɪɒn/; Ancient Greek: Πανδίων) was a legendary King of Athens, the son and heir to Erichthonius of Athens and his wife, the naiad Praxithea.
Pandion married a naiad, Zeuxippe, and they had two sons Erechtheus and Butes, and two daughters Procne and Philomela.
[4] Pandion I was the fifth king of Athens in the traditional line of succession as given by the third century BC Parian Chronicle, the chronographer Castor of Rhodes (probably from the late third-century Eratosthenes) and the Bibliotheca.
Castor makes Pandion I the son of Erichthonius (the earliest source for this)[6] and says he ruled for 40 years (1437/6–1397/6 BC).
[8] According to the Bibliotheca, Pandion fought a war with Labdacus, the king of Thebes, over boundaries, and married his daughter Procne to Tereus in exchange for help in the fighting,[9] and it was during his reign that the gods Demeter and Dionysus came to Attica.
