Marcus Vipsanius Agrippa - Antony and Cleopatra

Antony and Cleopatra

Agrippa was again called away to take command of the fleet when the war with Antony and Cleopatra broke out. He captured the strategically important city of Methone at the southwest of the Peloponnese, then sailed north, raiding the Greek coast and capturing Corcyra (modern Corfu). Octavian then brought his forces to Corcyra, occupying it as a naval base. Antony drew up his ships and troops at Actium, where Octavian moved to meet him. Agrippa meanwhile defeated Antony's supporter Quintus Nasidius in a naval battle at Patrae. Dio relates that as Agrippa moved to join Octavian near Actium, he encountered Gaius Sosius, one of Antony's lieutenants, who was making a surprise attack on the squadron of Lucius Tarius, a supporter of Octavian. Agrippa's unexpected arrival turned the battle around.

As the decisive battle approached, according to Dio, Octavian received intelligence that Antony and Cleopatra planned to break past his naval blockade and escape. At first he wished to allow the flagships past, arguing that he could overtake them with his lighter vessels and that the other opposing ships would surrender when they saw their leaders' cowardice. Agrippa objected that Antony's ships, although larger, could outrun Octavian's if they hoisted sails, and that Octavian ought to fight now because Antony's fleet had just been struck by storms. Octavian followed his friend's advice.

On September 2 31 BC, the Battle of Actium was fought. Octavian's victory, which gave him the mastery of Rome and the empire, was mainly due to Agrippa. As a token of signal regard, Octavian bestowed upon him the hand of his niece Claudia Marcella Major in 28 BC. He also served a second consulship with Octavian the same year. In 27 BC, Agrippa held a third consulship with Octavian, and in that year, the senate also bestowed upon Octavian the imperial title of Augustus.

In commemoration of the Battle of Actium, Agrippa built and dedicated the building that served as the Roman Pantheon before its destruction in 80AD. Emperor Hadrian used Agrippa's design to build his own Pantheon, which survives in Rome. The inscription of the later building, which was built around 125, preserves the text of the inscription from Agrippa's building during his third consulship. The years following his third consulship, Agrippa spent in Gaul, reforming the provincial administration and taxation system, along with building an effective road system and aqueducts.
