An ancient monarchy at the times of the Trojan War, the city was ruled by a number of tyrants during the Archaic and Classical period and became a democracy in the 3rd century BC.
[1] For some centuries the suzerainty of Argos remained, but after 676 BC Sicyon regained its independence under a line of tyrants called the Orthagorides after the name of the first ruler Orthagoras.
[4] Besides reforming the city's constitution to the advantage of the Ionians and replacing Dorian cults with the worship of Dionysus, Cleisthenes gained a reputation as the chief instigator and general of the First Sacred War (590 BC) in the interests of the Delphians.
After the fall of the tyrants their institutions survived until the end of the 6th century BC, when Dorian supremacy was re-established, perhaps by the agency of Sparta under the ephor Chilon, and the city was enrolled in the Peloponnesian League.
Later in the 5th century BC, Sicyon, like Corinth, suffered from the commercial rivalry of Athens in the western seas, and was repeatedly harassed by squadrons of Athenian ships.
64/65 During the 4th century BC, the city reached its zenith as a centre of art: its school of painting gained fame under Eupompus and attracted the great masters Pamphilus and Apelles as students, while Lysippus and his pupils raised the Sicyonian sculpture to a level hardly surpassed anywhere else in Greece.
In this period Sicyon was the undisputed center of Greek painting with its school attracting famous artists from all over Greece, including the celebrated Apelles and Pausias.
When the Macedonian commander Alexander was murdered in Sicyon in 314 BC, his wife Cratesipolis took control of the city and ruled it for six years, until she was induced by king Ptolemy I to hand it over to the Egyptians.
In 303 BC Sicyon was conquered by Demetrius Poliorcetes who razed the ancient city in the plain and built a new wall on the ruins of the old Acropolis on the high triangular plateau which resulted sufficient for the reduced populace.
Their rule ended, probably around the start of the Chremonidean War in 267 BC, when they were expelled by the people who elected their leader Cleinias to govern the city on a democratic ground.
This move ended the internal strife and Aratus remained the leading figure of Achaean politics until his death in 213 BC, during a period of great achievements.
The destruction of Corinth (146 BC) brought Sicyon an acquisition of territory and the presidency over the Isthmian games; yet in Cicero's time it had fallen deep into debt.
It became a bishop's seat and, judging by its later designation "Hellas," it appears to have become a haven for populations seeking refuge from the settlement of Slavic groups in Greece during the 7th century.
[7] When Nerio died in 1394, Corinth and Vasilika were inherited by his daughter, Francesca Acciaioli, who had recently married Carlo I Tocco, the count palatine of Cephalonia and Zante.
[9] The Ottoman Turks invaded and subjugated Corinth and Vasilika, alongside other northern Moreot towns and fortresses, in 1458, two years before completing the conquest of the Morea in 1460–1461.
Mecone is also described by Callimachus as "the seat of the gods", and as the place where the brother deities Zeus, Poseidon and Hades cast lots for what part of the world each would rule.
