The sculptures are in some instances accompanied by inscriptions.

One of these is, like those of Artaxerxes, bilingual, Greek and Persian.

The Greek inscription runs as follows: [Illustration: PAGE 289] In the main, Sapor, it will be seen, follows the phrases of his father Artaxerxes; but he claims a wider dominion.

Artaxerxes is content to rule over Ariana (or Iran) only; his son calls himself lord both of the Arians and the non-Arians, or of Iran and Turan.

We may conclude from this as probable that he held some Scythic tribes under his sway, probably in Segestan, or Seistan, the country south and east of the Hamoon, or lake in which the Helmend is swallowed up.
