On his return to power, a pair of Roman agents convinced Ptolemy VI to grant Ptolemy VIII control of
Cyrenaica. Ptolemy VIII departed for
Cyrene, but he was not satisfied. In late 163 or early 162 BC, he went to Rome to request help. The Senate was convinced that the division was unfair, declaring that Ptolemy VIII ought to receive Cyprus as well. The ancient historian
Polybius believed that the Senate made this decision with the conscious goal of weakening Ptolemaic power.
Titus Manlius Torquatus and
Gnaeus Cornelius Merula were sent as envoys to force Ptolemy VI to concede this. From Rome, Ptolemy VIII went to Greece where he recruited soldiers (including
Damasippus) in preparation for an expedition to seize Cyprus by force. He had sailed to
Rhodes with this fleet when he encountered Torquatus and Merula, who convinced him to discharge his troops and return to Cyrene. He went to the border between Egypt and Cyrene, waiting with a force of 1,000 Cretan mercenaries at a small town just west of
Paraetonium for the results of the Roman negotiations with Ptolemy VI. Ptolemy VIII had been waiting there for forty days when Ptolemy Sempetesis, the governor that Ptolemy VIII had left in charge of Cyrene in his absence, suddenly raised a revolt. Ptolemy VIII marched to suppress the revolt and was defeated in battle. He regained control over Cyrene by the end of 162 BC, but it is not known whether he achieved this by negotiation or military action. This expedition lasted up to a year, before fierce Cypriot resistance forced him to abandon the enterprise. In 156 or 155 BC, Ptolemy VIII faced a failed assassination attempt, which he attributed to his older brother. Ptolemy VIII was besieged by his older brother at
Lapethus and was captured. Ptolemy VIII was persuaded to withdraw from Cyprus, in exchange for continued possession of Cyrenaica, an annual payment of grain, and a promise of marriage to one of Ptolemy VI's infant daughters (probably
Cleopatra Thea) once she came of age.
Relations with Rome Throughout his time as king in Cyrene, Ptolemy VIII maintained extremely close relations with Rome. From 162 BC, he was an official
amicus et socius (friend and ally) of the Roman Republic. During his time in Rome he is said to have met
Cornelia. In 152 BC, after the death of her husband,
Tiberius Sempronius Gracchus, Ptolemy VIII allegedly asked for her hand in marriage, which she refused. This encounter was popular in neoclassical art, but it is unlikely that it ever actually took place. Even if untrue, the story may reflect close ties between Ptolemy VIII and the
gentes Cornelia and Sempronia. By contrast, Ptolemy VI seems to have maintained ties with
Cato the Elder. This act is not mentioned by any literary source but it fits with the very close alignment between Ptolemy VIII and the Romans that is attested in the literary sources. Similar testaments are known from other contemporary monarchs, notably
Attalus III of
Pergamum. They were often used by monarchs as an attempt to protect themselves from assassination or coup. Ptolemy VIII's will would be the earliest example of this practice. However, it is quite possible that the text of the testament itself is authentic, but was only publicly disseminated in inscriptions by the Romans after they took over the country.
Relations with Numidia Ptolemy VIII maintained a significant relationship with
Numidia, highlighted by his close friendship with King
Massinissa. This connection was established in 163 BC when Ptolemy VIII ascended to the throne of
Cyrene. During this period, Massinissa was renowned for fostering relationships with Greek states and promoting a policy of
Hellenization. Ptolemy VIII's interactions with Numidia were notably demonstrated by the dedication of a bust to Massinissa's son,
Mastanabal, a distinguished athlete. The two rulers are believed to have met between 163 and 148 BC, with a plausible location being Massinissa's main residence at
Cirta. While the exact details of their meeting remain uncertain,
Athenaeus' references to Ptolemy VIII's Memoirs suggest the occurrence of a banquet hosted by Massinissa. During this event, Massinissa reportedly expressed astonishment at the
Syracusans' preference for pet monkeys over children, an anecdote recounted by Ptolemy VIII.
Spectacle and construction As king of Cyrene, Ptolemy VIII attempted to display the Hellenistic royal virtue of
tryphe (luxury). The main priesthood in Cyrene was the position of the priest of
Apollo. Ptolemy VIII assumed this position and discharged his duties, especially the hosting of feasts, extremely sumptuously. He also engaged in a wide-ranging construction project in the city. A large tomb west of
Ptolemais seems to have been intended as his final resting place. ==Second reign (145–132/131 BC)==
