Restan, or Arethus, at the equal distance of sixteen miles between Edesa (Hems) and Epiphania (Hamath), was founded, or at least named, by Seleucus Nicator. Its peculiar era dates from the year of Rome 685, according to the medals of the city. In the decline of the Seleucides, Emesa and Arethusa were usurped by the Arab Sampsiceramus, whose posterity, the vassals of Rome, were not extinguished in the reign of Vespasian.
