Note 3 — Chapter IX · THE EUPHRATES FRONTIER AND THE PARTHIANS.

The viceroys of Persis are called in their title constantly “Zag Alohin” (at least the American signs correspond to these words, which were presumably in pronunciation expressed in the Persian way), son of God (Mordtmann, Zeitschrift für Numismatik, iv. 155 f.), and to this corresponds the title θεοπάτωρ on the Greek coins of the great-kings. The designation “God” is also found, as with the Seleucids and the Sassanids.—Why a double diadem is attributed to the Arsacids (Herodian, vi. 2, 1) is not cleared up.
