l as in the
struggle with Aristonicus, not only remained in possession beyond
the Halys, but also in substance retained the protectorate over
the Paphlagonian and Galatian dynasts. It is only on this hypothesis
that we can explain how Mithradates, ostensibly for his brave
deeds in the war against Aristonicus, but in reality for
considerable sums paid to the Roman general, could receive Great
Phrygia from the latter after the dissolution of the Attalid
kingdom. How far on the other hand the kingdom of Pontus about
this time extended in the direction of the Caucasus and the sources
of the Euphrates, cannot be precisely determined; but it seems
to have embraced the western part of Armenia about Enderes and
Divirigi, or what was called Lesser Armenia, as a dependent
satrapy, while the Greater Armenia and Sophene formed distinct
and independent kingdoms.

Syria and Egypt

While in the peninsula of Asia Minor Rome thus substantially conducted
the government and, although much was done without or in opposition
to her wishes, yet determined on the whole the state of possession,
the wide tracts on the other hand beyond the Taurus and the Upper
Euphrates as far down as the valley of the Nile continued to be mainly
left to themselves. No doubt the principle which formed the basis of
the regulation of Oriental affairs in 565, viz. That the Halys should
form the eastern boundary of the Roman client-states,(35) was not
adhered to by the senate and was in its very nature untenable.
The political horizon is a self-deception as well as the physical;
if the state of Syria had the number of ships of war and war-elephants
allowed to it prescribed in the treaty of peace,(36) and if the
Syrian army at the bidding of the Roman senate evacuated Egypt when
half-won(37), these things implied a complete recognition of hegemony
and of clientship. Accordingly the disputes as to the throne in
Syria and in Egypt were referred for settlement to the Roman
government. In the former after the death of Antiochus Epiphanes
(590) Demetrius afterwards named Soter, the son of Seleucus IV,
living as a hostage at Rome, and Antiochus Eupator, a minor, the son
of the last king Antiochus Epiphanes, contended for the crown; in
the latter Ptolemy Philometor (573-608), the elder of the two
brothers who had reigned jointly since 584, had been driven from
the country (590) by the younger Ptolemy Euergetes II or the Fat
(d. 637), and had appeared in person at
