sish'-i-on (Sikuon, Sukuon, Sukion): Mentioned in 1 Macc 15:23 in the list of countries and cities to which Lucius the Roman consul (probably Lucius Calpurnius Piso, 139 BC) wrote, asking them to be friendly to the Jews. The Jewish dispersion had already taken place, and Jews were living in most of the seaports and cities of Asia Minor, Greece and Egypt (compare Sib Or 3:271, circa 140BC , and Philo).
Sicyon was situated 18 miles West of Corinth on the south side of the Gulf of Corinth. Its antiquity and ancient importance are seen by its coins still extant, dating from the 5th century. Though not as important as Corinth in its sea trade, the burning of that city in 143 BC, and the favor shown to Sicyon by the Roman authorities in adding to its territory and assigning to it the direction of the Isthmian games, increased its wealth and influence for a time.
