Pompey was employed during the remainder of this year and the beginning of the following in visiting the cities of
Cilicia and
Pamphylia, and providing for the government of the newly-conquered districts. During his absence from Rome (
66 BC), Pompey was nominated to succeed
Lucius Licinius Lucullus in the command, take charge of the
Third Mithridatic War and fight
Mithridates VI of Pontus in the East. Lucullus, a well-born patrician, made it known that he was incensed at the prospect of being replaced by a "new man" such as Pompey. Pompey responded by calling Lucullus a "
Xerxes in a toga." Lucullus shot back by calling Pompey a "vulture" because he was always fed off the work of others, referring to his new command in the present war, as well as Pompey's actions at the climax of the war against Spartacus. The bill conferring upon him this command was proposed by the tribune
Gaius Manilius, and was supported by Cicero in an oration which has come down to us (
pro Lege Manilia). Like the Gabinian law, it was opposed by the whole weight of the aristocracy, but was carried triumphantly. The power of Mithridates had been broken by previous victories of Luculus, and it was only left to Pompey to bring the war to a conclusion. This command essentially entrusted Pompey with the conquest and reorganization of the entire Eastern Mediterranean. Also, this was the second command that Caesar supported in favor of Pompey.
On the approach of Pompey, Mithridates retreated towards
Armenia, but he was defeated; and as
Tigranes the Great now refused to receive him into his dominions, Mithridates resolved to plunge into the heart of
Colchis, and thence make his way to his own dominions in the
Cimmerian Bosporus. Pompey now turned his arms against Tigranes; but the Armenian king submitted to him without a contest, and was allowed to conclude a peace with the republic. In
65 BC Pompey set out in pursuit of Mithridates, but he met with much opposition from the
Iberians and
Albanians; and after advancing as far as the River
Phasis (now
Fax or Rioni River), he resolved to leave these districts. He accordingly retraced his steps, and spent the winter at
Pontus, which he made into a Roman province. In
64 BC he marched into
Syria, deposed the king
Antiochus XIII Asiaticus, and made that country also a Roman province. In
63 BC, he advanced further south, in order to establish the Roman supremacy in
Phoenicia, Coele-Syria, and
Israel. After that he captured
Jerusalem. At the time Judaea was racked by civil war between two Jewish brothers who created religious factions:
Hyrcanus and
Aristobulus. The civil war was causing instability, and it exposed Pompey's unprotected flank. He felt that he had to act. Both sides gave money to Pompey for assistance, and a picked delegation of Pharisees went in support of Hyrcanus. Pompey decided to link forces with the good-natured Hyrcanus, and their joint army of Romans and Jews besieged Jerusalem for three months, after which it was taken from Aristobulus. Aristobulus was crafty, though, and later succeeded in temporarily usurping the throne from Hyrcanus. Subsequently, King Herod I executed Hyrcanus in 31 BC.
Pompey entered the
Holy of Holies; this was only the second time that someone had dared to penetrate into this sacred spot. He went to the Temple to satisfy his curiosity about stories he had heard about the worship of the
Jewish people. He made it a priority to find out whether or not the Jews had no physical statue or image of God in their most sacred place of worship. To Pompey, it was inconceivable to worship a God without portraying him in a type of physical likeness, like a statue. What Pompey saw was unlike anything he had seen on his travels. He found no physical
statue, religious image, or
pictorial description of the Hebrew God. Instead, he saw the
Torah scrolls, and was thoroughly confused.
It was during the war in Judea that Pompey heard of the death of Mithridates.
With Tigranes as a friend and ally of Rome, the chain of Roman protectorates now extended as far east as the
Black Sea and the
Caucasus. The amount of tribute and bounty Pompey brought back to Rome was almost incalculable:
Plutarch lists 20,000
talents in gold and silver added to the treasury, and the increase in taxes to the public treasury rose from 50 million to 85 million
drachmas annually. His administrative brilliance was such that his dispositions endured largely unchanged until the fall of Rome.
Pompey conducted the campaigns of
65 to
62 BC and Rome annexed much of Asia firmly under its control. He imposed an overall settlement on the kings of the new eastern provinces, which took intelligent account of the geographical and political factors involved in creating Rome's new frontier on the East.
