Arsa'ces
(
Ἀρσάκης), the name of the founder of the Parthian empire, which was also borne by all his successors, who were hence called the Arsacidae. Pott (
Etymologische Forschungen, ii. p. 172) supposes that it signifies the " Shah or King of the Arii ;" but it occurs as a Persian name long before the time of the Parthian kings. Aeschylus (
Aesch. Pers. 957) speaks of an Arsaces, who perished in the expedition of Xerxes against Greece; and Ctesias (
Pers. cc. 49, 53, 57, ed. Lion) says, that Arsaces was the original name of Artaxerxes Mnemon.
