Res Gestae

But the frontier of the East, extending a long distance in a straight line, reaches from the banks of the Euphrates to the borders of the Nile, being bounded on the left by the Saracenic races and on the right exposed to the waves of the sea. Of this district Nicator Seleucus took possession and greatly increased it in power, when by right of succession he was holding the rule of Persia after the death of Alexander of Macedon; and he was a successful and efficient

king, as his surname Nicator indicates.
