Cecrops II , legendary King Of Athens , dies after a reign of 40 years and is succeeded by his son Pandion II . Pandion II was later driven into exile from Athens by the sons of Cecrops II 's brother (or possibly nephew) Metion , so that Metion could take power. Pandion II fled to Megara , where he married the King's daughter and eventually inherited the throne. After his death, Pandion II 's sons returned to Athens and drove out the sons of Metion .
