Arsaces I

A later tradition, preserved by Arrian, derives Arsaces I. and Tiridates from the Achaemenian king Artaxerxes II., but this has evidently no historical value.

Character of Mithridates I. The Parthian institutions possessed great simplicity; and it is probable that they took a shape in the reign of Arsaces I., or, at any rate, of Tiridates, which was not greatly altered afterwards.

If the Parthian monarchy owed its origin to Arsaces I., it owed its consolidation, and settled establishment to Arsaces II., or Tiridates.
