[490] Ægeus had by Mêdea (who took refuge at Athens after her flight from Corinth) a son named Mêdus, who passed into Asia, and was considered as the eponymus and progenitor of the Median people. Datis, the general who commanded the invading Persian army at the battle of Marathôn, sent a formal communication to the Athenians announcing himself as the descendant of Mêdus, and requiring to be admitted as king of Attica: such is the statement of Diodôrus (Exc. Vatic. vii.-x. 48: see also Schol. Aristophan. Pac. 289).
... “Te, maxime Theseu, Mirata est Marathon Cretæi sanguine Tauri: Quodque Suis securus arat Cromyona colonus, Munus opusque tuum est. Tellus Epidauria per te Clavigeram vidit Vulcani occumbere prolem: Vidit et immanem Cephisias ora Procrustem. Cercyonis letum vidit Cerealis Eleusin. Occidit ille Sinis,” etc.
Respecting the amours of Thêseus, Ister especially seems to have entered into great details; but some of them were noticed both in the Hesiodic poems and by Kekrops, not to mention Pherekydês (Athen. xiii. p. 557). Peirithous, the intimate friend and companion of Thêseus, is the eponymous hero of the Attic dême or gens Perithoidæ (Ephorus ap. Photium, v. Περιθοῖδαι).
