Jerash is the site of the ruins of the Greco-Roman city of Gerasa, also referred to as Antioch on the Golden River. Ancient Greek inscriptions from the city support that the city was founded by Alexander the Great and his general Perdiccas, who allegedly settled aged Macedonian soldiers there during the spring of 331 BC, when he left Egypt and crossed Syria en route to Mesopotamia. However, other sources, namely the city's former name of "Antioch on the Chrysorrhoas, point to a founding by Seleucid King Antioch IV, while still others attribute the founding to Ptolemy II of Egypt.
