I finished reading,
The Poison King: The Life and Legend of Mithradates, Rome's Deadliest Enemy by Adrienne Mayor and
Mithridates VI and the Pontic Kingdom by Jakob Munk Hojte, and I think that Mithridates (M) was an influence on Caesar, in particular for his social policy and his mercy toward his enemies.
Below, I will quote only the interesting facts (see http://www.kavehfarrokh.com/iranica/parthian-era/professor-brian-mcging-mithradates-vi-eupador-of-the-pontus-kingdom/ for an overview of his life).
Background
Mithradates VI Eupator Dionysos (r. 120-63 BCE), last king of Pontus, the Hellenistic kingdom that emerged in northern Asia Minor in the early years of the 3rd century BCE. He is noted primarily for his opposition to Rome. Of the three wars he fought against Rome, the first (89-85 BCE), in which his armies swept through Asia Minor and Greece, eventually only meeting defeat at the hands of Sulla, identified him as Rome’s most determined foreign enemy since Hannibal.
Sources:
The sources we have on Mithridates and the Mithridatic Wars are few and somewhat unreliable. The only primary sources available are written by Roman historians such as Appian of Alexandria, Plutarch, and Cassius Dio. These accounts have to be considered biased because they were writing about a war between their nation and that of an enemy. Indeed, all three refer to Mithridates as a “barbarian.” Appian‟s Mithridatica is the only thorough account of the war and is very valuable. It is, however, full of errors and contains minimal chronology. Plutarch‟s bibliographies of Lucullus and Sulla are intended to show them in very favorable terms. Ancient historian Frank Burr Marsh wrote in his history of Rome that we “only know Mithridates through his enemies.”
Furthermore, all were born in the common era, over one hundred years after the end of Mithridates‟s life. They used memoirs from Roman generals and legislation as their main sources of information. Finally, these sources disagree on many key details. The sources record different numbers of strength for armies and navies, different numbers of casualties, and varying terms of treaties. Some of the sources leave parts of the history out and other sections have not been preserved.
Birth:
The greatness of M reign was foretold by the heavens: in the year of his birth (135 BC), a comet appeared, and in the year of his accession to the throne (119 BC) a comet appeared for
70 days according to Justin, filling a quarter of the whole sky and blocking out the sun. When still a baby, M was struck by lightning, an incident supposed to provide the explanation for his surname Dionysos (The worship of Dionysos had been banned by the Roman senate in 186 BC, because of Dionysus’s association with slave revolts and foreign rebellions.)
He was the first, with Tigranes II of Armenia,
to use a representation of a comet on his coins. Tigranes was M most trusted ally, his queen was M favorite daughter. According to the Armenian scholars the comet on the coin of Tigranes was a representation of Halley’s Comet, which appeared in 87 BC during his reign.
M comets of 135 and 119 appeared in the constellation of Pegasus. This position in the sky explain why he chose the wings horse as his personal emblem.
The myth of Pegasos was a perfectly Greek legend, which however had connections to Perseus, the mythical ancestor of the Persians. After Perseus had killed Gorgo, Pegasos flew out of the beheaded monster. Similar references to Perseus are found on many of the Pontic bronze coins. The eight-pointed star and moon sickle seen above the head of Pegasos is the emblem either of the land of Pontos or the Pontic royal house, and it appears on all silver and gold coins.(Hojte)
These sensational events and portents from so many different sources predicting the fall of an evil empire and the advent of a savior-king born under an Eastern star, became intertwined and loomed lard in M story during his lifetime. These oracles and the comets nourished the king’s self-image and his official publicity. The prophecies helped create fertile ground for popular support of his campaign against the tyranny of Rome. M, “the oriental savior king of oracles and prophecies” hoped that all people “would see in him the king from the east destined to bring about the destruction of Rome foretold in oracles.”(Adrienne Mayor)
Social and foreign policies
M grand strategy for the Black Sea was to secure a co-prosperity trade zone and tax it fairly. M farsighted vision offered a positive alternative to Rome’s rapacious greed and violent resources extraction in its early period of conquest. Instead of continual war, M offered peace. Instead of imposing bloodsucking taxes and debt, M would tax moderately and reinvest taxes in military measures to ensure security. M stood for a new vision of mutual prosperity, while the Romans of the late Republic pursued corruption, selfish profit and plunder.(Adrienne Mayor)
M first acts as the savior of Anatolia were social reforms aimed at redressing complaints against the Romans and their supporters. In what the historian Luis Ballesteros Pastor calls the “Mithridatic Revolution”, M relieved public and private debts, canceling loans owed to Roman and Italian creditors, winning support from the middle and lower classes.(Adrienne Mayor)
Mithridates the Merciful and Cruel
M had a reputation of cruelty and clemency. After the defeat of Nicomedes IV of Bithynia, M made
“a surprising announcement. All the captives were free to go. His men divided up the supplies, handing out Nicomedes provisions, foods, clothing and coins to each enemy soldier for his journey home. This benevolent act, and others like it, broadcast by word of mouth, gave M a reputation for clemency toward his enemies. (…) News of his spectacular victory and his magnanimous freeing of prisoners of war spread over the land, convincing many cities to take up his cause, eager to welcome M “ as god and savior”. Ancient writers tell how the populace of many Anatolian cities dressed in white garments and flocked to greet M, requesting his help against the Romans and acclaiming him with divine titles.(Adrienne Mayor)
Mithridates had treated another Roman general, Oppius, leniently and set him free.
However, Aquilius was forced to endure a brutal death. Since it was his greed that had set the war in motion (persuading the Bithynians and Cappadocians to invade Pontus), Mithridates ordered molten gold poured into Aquilius' mouth.
Heliopolis and the city of the sun (133 BC)
This story is not related to M, but it’s very interesting.
Eumenes III (Εὐμένης Γʹ; originally named Aristonicus, in Greek Aristonikos Ἀριστόνικος) was the pretender to the throne of Pergamon.
When the Pergamene King Attalus III (138–133 BC) died in 133 BC, he bequeathed his kingdom to the Romans. Because the Romans were slow in securing their claim, Aristonicus, who claimed to be the illegitimate son of the earlier Pergamene King Eumenes II (197–160 BC), father of Attalus III, filled the power vacuum, claiming the throne and taking the dynastic name Eumenes III.
In central Anatolia, Eumenes III established a utopian city-state, called Heliopolis. The citizens were free and equal, and Eumenes promised to liberate all slave and cancel debts. He was joined by Blossius of Cumae, the Stoic who had been a supporter of Tiberius Gracchus.
All these developments greatly alarmed the Romans, and they sent an army against him. Eumenes III was defeated and captured in 129 BC by a Roman force under Marcus Perperna, the consul for 130 BC in the siege of Thyatira. After his surrender, he was paraded through Rome and executed by strangulation.
But the citizens of Heliopolis continue to resist after the death of Eumenes.
The Senate dispatches the consul Manius Aquilius to crush the insurrection. Aquillius faced a series of long-drawn-out sieges before he could occupy the land and set up the new government. To bring the war to a quick end, Aquillius resorted to a ruthless solution. He ordered his men to pour poison into the water supplies of the besieged cities. This biological weapon killed soldiers and noncombatants alike, and Aquillius’s army easily overran the cities.(Adrienne Mayor)
Asiatic Vespers or the roman Shoah
In 89 BC, Mithridates Eupator was at the height of his power. He was secure in an alliance with Parthian-dominated Armenia and Parthia herself. He had received support from many peoples, tribes and cities around the Black Sea.
As a whole, a huge military force, numbering more than 200,000 soldiers, was at his disposal. The Social War in Italy offered a good opportunity for anti-Roman actions on the part of the Pontic king in Anatolia.
So, according to ancient authors, in 88 BC, Mithridates orchestrated a massacre of Roman and Italian settlers remaining in several Anatolian cities, essentially wiping out the Roman presence in the region( 80 000 deaths according to Appien, 150 000 for Putarch.)
The Asiatic Vespers (also known as the Vespers of 88 BC) refers to an infamous episode during the First Mithridatic War. In response to increasing Roman power in Anatolia, the king of Pontus, Mithridates the Great, tapped into local discontent with the Romans and their taxes to orchestrate the execution of 80,000 Roman and Italian citizens and other foreigners in Asia Minor. The massacre was planned scrupulously to take place on the same day in several towns scattered over Asia Minor. The massacre led to the Roman Senate committing a huge invasion force aimed at breaking the power of the Kingdom of Pontus and eventually annexing their territory in a series of conflicts known as the Mithridatic Wars.
The name was retrospectively given to the massacre by analogy with the Sicilian Vespers of 1282.
After the massacre, Sulla came and slaughtered Greece and Asia Minor.
However, this massacre doesn’t match the foreign policy of M against Rome. In studying the foreign policy of M, Jesper Majbom Madsen concludes:
In summation: Mithridates’ policies towards Rome were in many ways defensive. Certainly his conquests, particularly in Anatolia, were against Roman interests. Yet it is important to stress that Mithridates did not attack the Roman Empire before the Roman commission and Nikomedes IV attacked his interests. When engaging in Kappadokia and Bithynia in 90 BC, Mithridates did not launch an attack on Asia, but tried to conceal his takeover of the two Anatolian kingdoms through the use of Sokrates and Armenia. Had he felt strong enough to challenge Rome and at that time desired a war on Rome, this would have been the best time to strike Asia. Instead, Mithridates chose a strategy, where he accepted every demand Rome was ready to put force behind indicating that war with the Romans was to be avoided. What Mithridates aimed at was enlarging his kingdom as far as possible, without engaging in a war with Rome, something he knew had historically led to the destruction of the challenging kingdom (Hojte) .
Further questions:
Scholars of ancient intelligence wonder how the clandestine order was delivered – orally? In writing? In code? (…) M “intelligence coup” is still a great puzzle, remarks Sheldon. “We do not know, to this day, how M coordinated this feat, how he communicated with his agents, or how he kept such a deadly plan secret”, for a month, especially in places like Tralles, where the ordre was discussed in the assembly. (Adrienne Mayor)
Mithridates and the Antikythera Shipwreck
According to the historian Attilio Mastrocinque, the Antikythera Shipwreck comes from Synope (the headquarter of M) during his reign: see http://www.pontos.dk/publications/books/bss-9-files/bss-9-18-mastrocinque
The Antikythera Shipwreck is a box into which a series of 31 gear wheels have been placed in order to make astronomic calculations with a precision and of a complication that one had thought could only be attained in modern times :see http://en.wikipedia.org/wiki/Antikythera_wreck
Mithraism and Mithridates
Roger Beck thinks that the Kingdom of Commagene was crucial to the spread of Mitraism in Rome:
I propose to locate Mithraism’s founding group among the dependants, military and civilian, of the dynasty of Commagene as it made the transition from client rules to Roman aristocrats. See http://azargoshnasp.net/Din/mysteriesofmithra.pdf
During the end of the II century, Commagene was annexed by Armenia and therefore was an allied of M. It was under Antiochus Theos (70-40) that the Kingdom took back his independence.
He was also an allied of the Cilician pirates.
Even if the birth of Mitraism in Rome was not borrow from Persia and was a creation of the West, the Iranian tradition centred on Mithra-worship must be explained.
See, The Religion and Cults of the Pontic Kingdom: Political Aspects, for an in-depth study of the religious aspects in Pontic Kingdom during the reign of Mithridates :
http://www.pontos.dk/publications/books/bss-9-files/bss-9-15-saprykin
Taking all this into account, we should say that the appearance of Bosporan terracottas representing Attis, Mithras, Mên and warriors with shields was due to religious syncretism and the spread of the official cults of Zeus Stratios and Dionysos under Mithridates VI. These figurines were popular among the soldiers and mercenaries who served in the Pontic army. They had different religious meanings, but their cults were mostly inspired by Zeus Stratios, protector and guardian of many spheres of life in the kingdom. The popularity of Zeus grew parallel to the spread of the cults of Dionysos, Perseus-Apollon, Mithras-Mên-Attis – official deities of the Mithridatids as basis for creating the image of a deified king.
There were three levels in Pontic religious ideology and royal propaganda.
First the Hellenic, which played the most central role in the deification of the ruler, mostly in the eyes of the Greek subjects, for whom Mithridates Eupator was proclaimed Dionysos and was associated with Ares, Perseus, Apollon, Herakles, and Helios – all sons of Zeus, the main cult in Pontos since the early Mithridatids.
Second the Phrygian-Anatolian, where Attis and Mên seemed to be the chief deities, and the latter was drawn into the royal cult, because Mithridates Eupator tried to associate himself with the local moon-god in order to rally the resident population around him.
Third the Iranian which was perhaps the least important, as the kings of Pontos, though half-Persian by origin, were scared to declare themselves to be descendants of Mithras and Ahura-Mazda, having proclaimed instead that they were equal to the Hellenic and Phrygian gods and heroes, where Perseus was a compromise between Greek beliefs and the Iranian essence of the dynasty.(Hojte)
Hypsicrates and Hypsicratea
Adrienne Mayor theorizes that the last spouse of Mithridates, Hypsicratea, and the historian writing under the name Hypsicrates were the same person.
Hypsicrates the historian was a Greek writer in Rome who flourished in the 1st century BC. His work does not survive, but scholars have conjectures about the writer and his work. He was associated probably with Pontus and wrote a history of the area that was possibly used by Strabo. He may be the same Hypsicrates who served as a slave for Julius Caesar and was freed by Caesar in 47 BC.
In 47 BC, Caesar crushed Pharnaces attempt to regain his father’s lost kingdom. Taking over Pontus, Caesar freed a prisoner of war named Hypsicrates at Amisus. This Hypsicrates accompanied Caesar as his historian on campaigns and wrote treatises on the history, geography, and military affairs of Pontus and the Bosporan Kingdom.
