The history of Sicyon presents a series of revolutions, in many points resembling those of Corinth. At what time, or in whose person, royalty was there extinguished, and what form of government succeeded it, we are not expressly informed; but, as we know that there was a class of bondsmen at Sicyon, answering to the helots, and distinguished by peculiar names, derived from their rustic dress or occupation, there can be little doubt that other parts of the Dorian system were also introduced there, and subsisted until a fortunate adventurer, named Orthagoras, or Andreas, overthrew the old aristocracy, and founded a dynasty, which lasted a century: the longest period, Aristotle observes, of a Greek tyranny. Orthagoras is said to have risen from a very low station--that of a cook--and was, therefore, probably indebted for his elevation to the commonalty. The long duration of his dynasty is ascribed by Aristotle to the mildness and moderation with which he and his descendants exercised their power, submitting to the laws and taking pains to secure the good will of the people. His successor, Myron, having gained a victory in the Olympic chariot-race in the thirty-third Olympiad, erected a treasury at Olympia, which was remarkable for its material, brass of Tartessus, which had not long been introduced into Greece; for its architecture, in which the Doric and Ionic orders were combined; and for its inscription, in which the name of Myron was coupled with that of the people of Sicyon. It may be collected, from an expression of Aristotle’s, that, though Myron was succeeded, either immediately or after a short interval, by his grandson Clisthenes, son of Aristonymus, this transmission of the tyranny did not take place without interruption or impediment; and, if this arose from the Dorian nobles, it would explain some points in which the government of Clisthenes differed from that of his predecessors.
