Anthemusias (Greek: Ανθεμουσιάς) or Charax Sidae was an ancient Mesopotamian town, according to Pliny and Strabo. Isidore of Charax says that it was 8 schoeni from Apamea near the Euphrates on the road to Seleucia, and Ptolemy places it “at the foot of a mountain called Caspius". The city was founded by one of the early Seleucids and, according to Ptolemy, was situated next to Apameia. Barthold maintained it was the medieval town of Arazi, 12 farsaḵs from Ray, Iran(Rhagae)
