He also coined money, and stamped it with the effigy of an ox, either in remembrance of the Marathonian bull, or of Taurus, the general of Minos, or because he would invite the citizens to agriculture. From this coinage, they say, ten oxen and a hundred oxen came to be used as terms of valuation. Having attached the territory of Megara securely to Attica, he set up that famous pillar on the Isthmus, and carved upon it the inscription giving the territorial boundaries. It consisted of two trimeters, of which the one towards the east declared:— Here is not Peloponnesus, but Ionia; and the one towards the west:— Here is the Peloponnesus, not Ionia.

For the games already instituted there in honor of Melicertes were celebrated in the night, and had the form of a religious rite rather than of a spectacle and public assembly. But some say that the Isthmian games were instituted in memory of Sciron, and that Theseus thus made expiation for his murder, because of the relationship between them; for Sciron was a son of Canethus and Henioche, who was the daughter of Pittheus.

However that may be, Theseus made a formal agreement with the Corinthians that they should furnish Athenian visitors to the Isthmian games with a place of honor as large as could be covered by the sail of the state galley which brought them thither, when it was stretched to its full extent. So Hellanicus and Andron of Halicarnassus tell us.
