was besieged in Perusia and starved into submission
(40 B. C.). Fulvia went to join Antony, while others of their faction fled
to Sextus Pompey who still held Sicily. Of great importance to Octavian
was his acquisition of Gaul which came into his hands through the death of
Antony's legate, Calenus. An indication of the approaching break between
Octavian and Antony was the former's divorce of his wife Clodia, and his
marriage with Scribonia, a relative of Sextus Pompey, whom he hoped to win
over to his side.

*Treaty of Brundisium, 40 B. C.* While Octavian had been involved in the
Perusian war, the Parthians had overrun the province of Syria, and in
conjunction with them Quintus Labienus, a follower of Brutus and Cassius,
penetrated Asia Minor as far as the Aegean coast. Antony thereupon
returned to Italy to gather troops to reestablish Roman authority in the
East. Both he and Octavian were prepared for war and hostilities began
around Brundisium, which refused Antony admittance. However, a
reconciliation was effected, and an agreement entered into which was known
as the treaty of Brundisium. It was provided that Octavian should have
Spain, Gaul, Sardinia, Sicily and Dalmatia, while Antony should hold the
Roman possessions east of the Ionian sea; Lepidus retained Africa, and
Italy was to be held in common. To cement the alliance Antony, whose wife
Fulvia had died, married Octavia, sister of Octavian.

*The treaty of Misenum, 39 B. C.* In the following year Antony and
Octavian were forced to come to terms with Sextus Pompey. He still
defiantly held Sicily and in addition wrested Sardinia from Octavian. His
command of these islands and of the seas about Italy enabled him to cut
off the grain supply of Rome, where a famine broke out. This brought about
a meeting of the three at Misenum in which it was agreed that Sextus
should govern Sardinia, Sicily and Achaia for five years, should be consul
and augur, and receive a monetary compensation for his father's property
in Rome. In return he engaged to secure peace at sea and convoy the grain
supply for the city. However, the terms of the treaty were never fully
carried out and in the next year Octavian and Sextus were again at war.
The former regained possession of Sardinia but failed in an attack upon
Sicily.

*Treaty of Tarentum, 37 B. C.* Meanwhile Antony had returned to the East
where in the years 39-37 B. C. his lieutenants won back the Asiatic
provinces from Labienus an
