About Ptolemy VI
Lived 184 BC – 145 BC (aged 38–39). Ptolemy VI was a sovereign.
Background and early life
Ptolemy VI was the eldest son of Ptolemy V and Cleopatra I. The early reign of Ptolemy V was dominated by the Fifth Syrian War (204–198 BC) against the Seleucid king Antiochus III, who completely defeated the Ptolemaic forces, annexed Coele-Syria and Judaea to his empire, and reduced Egypt to a subordinate position. Under a peace treaty, Ptolemy V married Antiochus III's daughter Cleopatra I in 194 BC.
Ptolemy VI was born in 186 BC, probably in May or June.
First reign (180–164 BC) Regencies Ptolemy VI, who was only six years old, was immediately crowned king, with his mother Cleopatra I as co-regent. In documents from this period, Cleopatra I is named before Ptolemy VI and coins were minted under the joint authority of her and her son. She probably died in late 178 or early 177 BC, though some scholars place her death in late 176 BC.
Eulaeus and Lenaeus sought to reinforce their authority by augmenting the dignity of Ptolemy VI. In early 175 BC, they arranged his marriage to his sister Cleopatra II. Brother-sister marriage was traditional in the Ptolemaic dynasty and was probably adopted in imitation of earlier Egyptian Pharaohs. The couple were incorporated into the Ptolemaic dynastic cult as the Theoi Philometores ('the Mother-loving Gods'), named in honour of the deceased Cleopatra I. Ptolemy VI and Cleopatra II were still young children, so the marriage was not consummated for many years; they would eventually have at least four children together.
Sixth Syrian War (170 BC–168 BC)
The Seleucid king Seleucus IV, Ptolemy VI's uncle, had followed a generally peaceful policy, but he was murdered in 175 BC. After two months of conflict his brother Antiochus IV secured the throne. The unsettled situation empowered the warhawks in the Ptolemaic court, and Eulaeus and Lenaeus were unable or unwilling to resist them, with Cleopatra I no longer alive. By 172 BC, preparations for war were underway. Rome and Macedon commenced the Third Macedonian War in 171 BC, lessening their ability to interfere with Ptolemaic affairs, and the Egyptian government considered the moment for war had come.
In October 170 BC, Ptolemy VIII was promoted to the status of co-regent alongside his brother and sister. The current year was declared the first year of a new era. John Grainger argues that the two brothers had become the figureheads for separate factions at court and that these ceremonies were intended to promote unity within the court in the run-up to war. Shortly afterwards, Ptolemy VI, now around sixteen, was declared an adult and celebrated his coming-of-age ceremony (the anakleteria). Antiochus seized Pelusium and then pursued the Egyptians, who had withdrawn to the Nile Delta.
This defeat led to the collapse of the Ptolemaic government in Alexandria. Eulaeus attempted to send Ptolemy VI to the Aegean island of Samothrace with the Ptolemaic treasury. Before this could happen, two prominent Ptolemaic generals, Comanus and Cineas, launched a military coup and took control of the Egyptian government. As Antiochus IV advanced on Alexandria, Ptolemy VI went out to meet him. They negotiated an agreement of friendship, which in effect reduced Ptolemy VI to a Seleucid client. When news of the agreement reached Alexandria, the people of the city rioted. Comanus and Cineas rejected the agreement and Ptolemy VI's authority, declaring Ptolemy VIII the sole king (Cleopatra II's position remained unchanged). Antiochus IV responded by placing Alexandria under siege, but he was unable to take the city and withdrew from Egypt in September 169 BC, as winter approached, leaving Ptolemy VI as his puppet king in Memphis and retaining a garrison in Pelusium.
Within two months, Ptolemy VI had reconciled with Ptolemy VIII and Cleopatra II and returned to Alexandria. The restored government repudiated the agreement that Ptolemy VI had made with Antiochus IV, and began to recruit new troops from Greece. In response, Antiochus IV invaded Egypt for a second time in the spring of 168 BC. Officially, this invasion was presented as an effort to restore Ptolemy VI's position against his younger brother. Antiochus IV quickly occupied Memphis, where he was crowned king of Egypt, and advanced on Alexandria. He left the country for unknown reasons, but came back shortly afterwards as Ptolemy VI started to cooperate with his brother. However, the Ptolemies had appealed to Rome for help over the winter; a Roman embassy led by Gaius Popillius Laenas confronted Antiochus IV at the town of Eleusis and forced him to agree to a settlement, bringing the war to an end.
Rebellions and expulsion (168–164 BC) The joint rule of the two brothers and Cleopatra II continued in the immediate aftermath of the war. However, the complete failure of the Egyptian forces had left the Ptolemaic monarchy's prestige seriously diminished and caused a permanent rift between Ptolemy VI and Ptolemy VIII.
Between 168 and 164 BC, Dionysius Petosarapis, a prominent courtier who appears to have been of native Egyptian origin, attempted to exploit the conflict in order to take control of the government. He went to the stadium and announced to the people of Alexandria that Ptolemy VI was plotting to assassinate Ptolemy VIII. Ptolemy VI managed to convince his younger brother that the charges were untrue and the two kings appeared together in the stadium, defusing the crisis. Dionysius fled the city and convinced some military contingents to mutiny. Heavy fighting took place in the Fayyum over the next year A new branch of government, the Idios Logos (Special Account), was established to manage estates that had become royal property as a result of confiscation or abandonment.
Late in 164 BC, From there he moved on to Cyprus, which remained under his control.
Conflicts with Ptolemy VIII and the Seleucids
Ptolemy VIII was not satisfied with Cyrenaica and went to Rome in late 163 or early 162 BC to request help. The Roman Senate agreed that the division was unfair, declaring that Ptolemy VIII ought to receive Cyprus as well. Titus Manlius Torquatus and Gnaeus Cornelius Merula were sent as envoys to force Ptolemy VI to concede this, but he procrastinated and obfuscated. On their return to Rome at the end of 162 BC, they convinced the Senate to abandon their alliance with Ptolemy VI and to grant Ptolemy VIII permission to use force to take control of Cyprus. The Senate offered him no actual support in this endeavour and Cyprus remained in Ptolemy VI's hands. In 158 or 154 BC, Ptolemy VI's governor of Cyprus, Archias, attempted to sell the island to Demetrius I for 500 talents, but he was caught and hanged himself before this plot came to fruition.
In 154 BC, after surviving an assassination attempt which he blamed on his brother, Ptolemy VIII again appealed for assistance against Ptolemy VI to the Roman Senate. The Senate agreed to send a second embassy led by Gnaeus Cornelius Merula and Lucius Minucius Thermus, equipped with troops, in order to enforce the transfer of Cyprus to his control. In response, Ptolemy VI besieged his younger brother at Lapethus and captured him, with the help of the Cretan League. He persuaded Ptolemy VIII to withdraw from Cyprus, in exchange for continued possession of Cyrenaica, an annual payment of grain, and a promise of marriage to one of his infant daughters (probably Cleopatra Thea) once she came of age.
As a result of the conflict with his brother, Ptolemy VI made particular efforts to advance his eldest son Ptolemy Eupator as heir. The young prince was made priest of Alexander and the royal cult in 158 BC, when he was only eight years old. At age fourteen, in spring 152 BC, Ptolemy Eupator was promoted to full co-regent alongside his parents, but he died in autumn of the same year. This left the succession very uncertain, since Ptolemy VI's remaining son was very young. He began advancing his daughter Cleopatra III, formally deifying her in 146 BC.
Intervention in Syria (152–145 BC)
A new claimant to the Seleucid throne, Alexander Balas, appeared in 153 BC. John Grainger proposes that Ptolemy VI provided Alexander with financial backing, naval transport, and secured Ptolemais Akko as a landing base for him. He argues that Alexander's chancellor Ammonius should be seen as a Ptolemaic agent. There is however no explicit evidence for this, and Boris Chrubasik presents Alexander's initial successes as accomplished without any Ptolemaic involvement, and challenges the identification of Ammonius as an Egyptian in particular. At any rate, an agreement between Ptolemy VI and Alexander was sealed in 150 BC, when Ptolemy VI married his teenage daughter Cleopatra Thea to Alexander in a ceremony at Ptolemais Akko.
By May 146 BC, however, Ptolemy VI was gathering troops. In 145 BC he invaded Syria while Alexander was putting down a rebellion in Cilicia. Alexander's vassal Jonathan Maccabee allowed Ptolemy VI to pass through Judaea without interference. Ostensibly, Ptolemy VI acted in support of Alexander against the latest claimant of the Seleucid throne, Demetrius II. In practice, Ptolemy VI's intervention came at a heavy cost; he took control of all the Seleucid cities along the coast, including Seleucia Pieria. He may also have started minting his own coinage in the Syrian cities. Ptolemy VI remarried his daughter to Demetrius II and continued his march northward. The commanders of Antioch, Diodotus and Hierax, surrendered the city to Ptolemy and crowned him king of Asia. For a short period, documents referred to him as King of Egypt and Asia, and he initiated a double regnal count, with his Egyptian Year 36 = his Syrian Year 1. However, fearing that a unification of the Ptolemaic and Seleucid kingdoms would lead to Roman intervention, Ptolemy VI decided to abandon the title. Instead, he limited himself to annexing Coele Syria and pledged to serve as a "tutor in goodness and guide" to Demetrius II.
Alexander returned from Cilicia with his army, but Ptolemy VI and Demetrius II defeated his forces at the Oenoparas river. Alexander then fled to Arabia, where he was killed. His severed head was brought to Ptolemy VI. For the first time since the death of Alexander the Great, Egypt and Syria were united. However, Ptolemy VI had been wounded in the battle and he died three days later. By late 145, Demetrius II had expelled all Ptolemaic troops from Syria and reasserted Seleucid control by leading his own forces all the way down to the Egyptian border. Ptolemy VI seems to have intended for his seven-year-old son, also named Ptolemy, to succeed him, but instead the Alexandrians invited Ptolemy VIII to assume the throne. Young Ptolemy was eventually eliminated by his uncle, apparently only after 143 BC, when he served as eponymous priest, and perhaps as late as 132/1 BC.
Regime Pharaonic ideology and Egyptian religion
Like his predecessors, Ptolemy VI fully embraced his role as pharaoh and maintained a mutually beneficial relationship with the traditional Egyptian priesthood. In particular, he maintained close ties with the worship of Ptah and Apis at Memphis. Ptolemy VI and Cleopatra II seem to have visited Memphis and stayed in the Serapeum there for the Egyptian New Year festival every year. During these visits, Ptolemy VI personally made the ritual temple offerings expected of the pharaoh.
In summer 161 BC, Ptolemy VI and Cleopatra II gathered a synod of all the priests of Egypt in order to pass a decree granting tax relief and other benefactions to the priests in exchange for cultic honours in Egyptian temples – part of a series of decrees that had been issued under each of his predecessors, going back to Ptolemy III. The decree survives only on one fragmentary stele known as CG 22184.
Relations with the Jews The Jewish historian Josephus emphasises Ptolemy VI's personal interest in the Jews and their well-being. There had been a Jewish community in Egypt since at least the fifth century BC and it had grown significantly since the establishment of Ptolemaic control over Jerusalem in 311 BC. By Ptolemy VI's reign, Jews had long been incorporated into the Ptolemaic army, and they enjoyed various privileges comparable to those possessed by Greeks and Macedonians in Egypt. A large group of new Jewish immigrants arrived in Egypt in the 160s BC, fleeing civil conflict with the Maccabees. This group was led by Onias IV, son of a former high priest who had been deposed by the Seleucids. Ptolemy VI permitted them to settle at Leontopolis, which became known as the Land of Onias, and to establish a temple with Onias as High Priest. The place is still known as Tell al-Jahudija (Hill of the Jews) today. Onias was also granted an important military position and his family became prominent members of the royal court. In Alexandria the Jews had their own quarter of the city with its own politeuma – a kind of self-governing community within the city, led by their own ethnarch. It is likely that this politeuma was established under Ptolemy VI.
Relations with Nubia
Until the reign of Ptolemy IV, the Ptolemies had controlled the region south of Aswan to the second cataract, which was known as the Triacontaschoenus or Lower Nubia and included rich gold mines. Throughout the 160s and 150s BC, Ptolemy VI reasserted Ptolemaic control over the northern part of Nubia. This achievement is heavily advertised at the Temple of Isis at Philae, which was granted the tax revenues of the Dodecaschoenus region in 157 BC. Decorations on the first pylon of the Temple of Isis at Philae emphasise the Ptolemaic claim to rule the whole of Nubia. The aforementioned inscription regarding the priests of Mandulis shows that some Nubian leaders at least were paying tribute to the Ptolemaic treasury in this period. In order to secure the region, the strategos of Upper Egypt, Boethus, founded two new cities, named Philometris and Cleopatra in honour of the royal couple.
