Eupatridai, Archons, and Areopagus

I argued in § II. (Ion and Theseus) that in the lost chapters of the Ἀθηναίων Πολιτεία Aristotle recorded (in connexion with the Synoikisis) the creation by Theseus of the Eupatrid Order, from whom the Archons were chosen: that this tallies with Thuc. II. 15: that Thucydides further suggests that the continuous existence of the Areopagus Council dates from the same time: that finally Council and Order stand to each other as patres and patricii did in Rome.
