Chapter Thirty-One: The Rise of Diomedes
The year is 186 BCE and Seleukeia is burning. Much of the city is already in flames, tens of thousands are dead or have fled the city for the refuge of nearby Babylon as soldiers swarm through the remains of the city looting and killing. At their head is Aristarchus, a member of the Seleucid family and respected general of the eastern frontiers. He has sworn revenge; everybody in the palace is going to die and there is nothing anybody can do to stop it. Inside the palace, Diomedes, 'Hand of the King', hurries to rally whatever defence he can and sends messengers to try and run Aristarchus' siege and get help. Whether he knows it or not, no help is coming; the empire has begun to fracture and beyond the narrow confines of Mesopotamia, it's every man for himself. Back in the palace, King Seleucus IV 'Epimanes' has been confined to his chambers, sustained by a steady supply of food and held under strict guard to prevent anyone from getting to him. After the things the king has already done, everybody knows he wont last long. Still, Diomedes needs him, he needs a king or his head will soon be on the chopping block. Only two men could break the siege now, both currently cutting a bloody swathe through the empire as they converge on the city. On one side, the self-styled Gorgias I a Seleucid general who has recently emerged from the chaos of Iranian politics in the 190s as a powerful figure and, on the other, the undefeated general Argeus I 'Aniketos', King of Egypt.
Note: This is a simplified family tree to emphasise the important figures for our narrative and not to provide a comprehensive outlook on the entire Seleucid family.
Everything had gone very very wrong by the 180s, a quite dramatic change over a period of only about 24 years. When we left off with the death of Seleucus III, the empire was still rather stable and intact for the most part but his death, and the accession of his eleven-year-old son Antiochus III. To really understand what happened here, however, we should take some time to step back and look at the rise of one of the most important figures of the age; Diomedes. To understand this, however, we should understand his personal relationship to the royal family itself. See, Diomedes wasn't just an aristocrat but a member of the royal family if only a very minor one. Nor was he alone. See, Seleucus I's second son Achaeus had four children named (confusingly) Antiochis, Alexander, Andromachus, Laodice and Laodice. To make matters even more difficult, his eldest son, Alexander, had married yet another Laodice, the daughter of Antiochus I and sister of Antiochus II. During his lifetime, Achaeus emerged as a very wealthy landowner, especially in Asia Minor, especially after his brother's defeat of the Gauls in the 270s after which Achaeus seems to have come into possession of extra lands around the Meander River. Upon his death in 265 BCE, the lands were largely split between his children with the lion's share going to his sons Alexander and Andromachus but with some lands and wealth being provided as dowries for his daughters.
For his part, Alexander remained active mostly in Asia Minor and was elevated by Seleucus II to be the king's representative in the region in 260 BCE. Upon Seleucus II's death, however, he was quick to change sides to Antiochus II and was rewarded with extra lands and allowed to keep his position. He would oversee most of Asia Minor for the next few decades until his death in 232 BCE. His son, Apollonios has made very little impact on our source evidence save for that he married a Greek woman from Samos and administered his share of his father's lands (which, again, had been split between he and his two brothers: Alexander and Demetrios) ably. His marriage would produce Aristarchus in 235 BCE, a name worth keeping in mind for his significance later on. Achaeus' daughter Laodice (the elder of the two Laodices) married a Macedonian elite named Polyphontes and sometime around 262 BCE gave birth to Callistratus 'Kalos' (not the same Callistratus who would later govern Macedonia however). This Callistratus would spend much of his time around the Seleucid court in Seleukeia and supposedly kept a close friendship as a young man with the poet Sosthenes in the 240s. He would also marry an Iranian woman by the name of Artunis, a marriage which would produce Gorgias in 239 BCE. In the 230s, Callistratus was made
satrap of Sogdiana and would remain in this position until 226 BCE when he died and the
satrapy was transferred. In 218 BCE, Seleucus appointed his son, Gorgias (then 21) as the new
satrap, a position he would hold for some 38 years until his death in 180 BCE. For his part, Gorgias would marry Agathokleia (a descendant of Antiochis, Achaeus' daughter) and produce two sons: Gorgias II, born in 219 BCE and Antiochus, born in 217 BCE.
Finally, we get to Diomedes, the great-grandson of Achaeus by his second son, Andromachus. Andromachus was active in Syria during Antiochus II's first war against the Ptolemies during the 250s, possibly as a sub-commander of some description and was granted lands in the region near Apamea in return for his service. Little is known about his son Alexander except that he was active in the court during the 240s and knew Callistratus 'Kalos' during his time there. His son Diomedes was born in 253 BCE and grew up in Apamea in Syria. At the age of 16, he travelled to Antioch and from there to Greece where he would spend a few years studying philosophy which he is said to have truly hated. At age 21, Diomedes joined the Seleucid court as something of a minor official. A year later, in 231, he was appointed as an
oikonomos, a minor financial official of a small region in northern Phoenicia. He excelled and by 229 had been appointed
dioiketes (financial officer for an entire region) in Syria itself, a position which put him in direct contact with Antiochus II. His rapid rise was probably just as much a result of his high born status and links to the Seleucid family, but he was also renowned for his financial talents even in his day. Between 229 and 227 BCE, he oversaw an increase in the tax revenue from Syria and was involved directly in the actual workings of the Seleucid financial system, allocating funds for projects and sending commands down the hierarchy as needed. In 228 BCE, he married Isadora, the daughter of the guard commander Sophokles.
In doing so, Diomedes aligned himself more and more with the pro-Macedonian faction under Queen Kleopatra. This was to prove a mistake since the outbreak of war in 227 BCE would precipitate a fall from grace for Diomedes over the next few years. During the Ptolemaic invasion, Diomedes' involvement at court fell to nearly nothing and he largely abandoned his post while Syria was under Ptolemaic occupation. This would lead to claims that he had collaborated with the invaders later in his life but there isn't sufficient evidence to say either way whether or not Diomedes aligned himself with the Ptolemies or not. Regardless, the 220s saw the rise of Ariobarzanes' influence at court and the decline of the pro-Macedonian faction as Antiochus II leaned ever more on his Iranian supporters. His death in 219 BCE sealed the deal and many of the pro-Macedonian aristocracy fell out of power including Diomedes as the Perso-Babylonian faction saw its own power increase between Ariobarzanes and Amestris. This all changed again, however, in 217 when the rebuilding process in Syria provided an opportunity for Diomedes to regain his influence. While Seleucus III was in Antioch, Diomedes travelled personally to the city and, daring to forgo court practice, simply approached the king himself, almost being arrested by Mithridates, the commander of the king's bodyguard since the early 210s, but avoiding arrest by claiming that he could so much as halve the costs of rebuilding parts of Antioch. According to Caiatinus, Diomedes was able to leverage his personal connections across Syria to obtain better prices on supplies and workmen and dramatically reduce the cost (although whether he achieved his 50% discount is unknown).
Regardless, the display was enough to earn him some favour and Diomedes was soon returned to his position as
dioiketes of Skyria. At a time of thorough rebuilding in the region, the result was that Diomedes saw frequent interactions with Seleucus who is said to have enjoyed his company and frequently sought him out for recommendations and discussion. All this, of course, despite the reservations of Ariobarzanes and his own faction. Soon enough, Ariobarzanes began recommending that Diomedes be removed from power for being too dangerous, especially given his ties to Sophokles, a known conspirator who had worked with Prince Antiochus and Kleopatra to plot rebellion. Diomedes, however, had a response to this, claiming that his marriage to Isadora was one of passion above reason and offering to divorce her should it make the king more comfortable but asking that he be allowed merely to continue acting as a loyal servant to the king. Accordingly, the two were divorced in 216 BCE but Diomedes did in fact continue to act as
dioiketes of Syria. In addition, Diomedes' two sons and two daughters were to be taken to the court as hostages for good behaviour.
In truth, Diomedes emerged from this no worse for wear and, over the next two years, continued to consolidate his own base of power. His focus was largely trying to reorganise the pro-Macedonian faction in the wake of Kleopatra's flight to Egypt in 219 and house arrest in 218 BCE. Astonishingly, Kleopatra would continue to live until 208 BCE, outliving Seleucus III and dying at the age of 71. Her flight to Egypt hadn't entirely destroyed the pro-Macedonian faction but it had fractured it into two. Some supported the possibility of an outright replacement for Seleucus right up until the murder of Demetrius in 215 BCE and flight of Berenice in 213/12 BCE. Diomedes, however, now became the voice of an increasingly popular Macedonian faction which was willing to work with Amestris and Ariobarzanes but championed the cause of Macedonian elites under the rule of Seleucus III and his descendants rather than those of Antiochus. Seeing an opportunity to outmanoeuvre their own enemies, Amestris and Ariobarzanes mostly allowed Diomedes to rally and continue operating until Demetrius' death in 215. See, with the downfall of Demetrius, Diomedes was able to make serious political gains, scooping up the support of many of the active Macedonian elites in the empire and forging a new pro-Macedonian faction. Their first real triumph here was the reconstruction of Antioch which took place almost entirely in the hands of these Macedonian elites and with little influence from the Perso-Babylonian faction under Ariobarzanes and Amestris.
Nor was this a small thing; the entire fabric of Seleucus' new grand city was Macedonian in character and design with reasonably few adaptations from Persian or Babylonian cities in its image. The statement being made was that the Seleucid empire and its kings were still Greco-Macedonian kings first and foremost and that they were rejecting an outright adoption of Persian precedent or infrastructure. Not that Diomedes abandoned these altogether since he himself was famously partial to Persian gardens and, during his regency, would fund the construction of a new garden on the banks of the Orontes known as the 'Antiochian Gardens' after its official patron, Antiochus III. The garden built by Diomedes was extensive, gathering plants from all across the Seleucid empire and even beyond with plants and animals brought from India including elephants and an enclosure which, for a few months, held a live captive tiger. Under better times, Diomedes' garden would have become a wonder in its own right but many of the features, including the fountains which were described by one historian as 'the most beautiful ever constructed' were never finished and the whole thing fell into disrepair under Argeus I. Diomedes' success, even if only ideological, had worked by his convincing the king to grant him increased authority over the hiring of architects, planners, and even construction teams many of which he brought from Greece and Macedonia, especially along the Ionian coast. During this period, Diomedes also spent time with Caiatinus and agreed to send the diplomat several marble statues for his rural villa back in Italy, a fact which demonstrates Diomedes' immense personal wealth.
In 214 BCE, Ariobarzanes died and his faction's power over the throne began to fracture. This stemmed from a steadily growing dislike between Queen Amestris and her father's cousin, Mithridates, then the commander of the royal guard. The exact origin of their distrust is unknown save for that he assumed that he would take command of the Perso-Babylonian faction and attempted to command her, something which she, as queen, deeply resented. In their squabbling, the supporters of Ariobarzanes soon found themselves forced to take sides, caught between the military power of Mithridates and his royal guard and the political power of Amestris. Looking to overcome Mithridates, Amestris turned to Diomedes asking for his help and together, the two hatched a plot. Between them, they forged reports that Mithridates was planning to usurp the throne and then squashed any information to the contrary. Between them Diomedes and Amestris worked to monopolise access to the king and, soon enough, he was only recieving word of Mithridates and his supposed treachery. Mithridates was arrested along with many of the royal bodyguards and executed.
In the aftermath, however, Diomedes was quick with suggestions. There were, he argued, many worthy of the position including, say, Aristarchus, a member of the royal clan and a first cousin once removed of Seleucus no less, a much closer relation to the king than Diomedes himself was. Aristarchus, to his credit, had military experience and may well have fought under Demetrius in the early 210s. While he was no great commander, or even especially clever by any means, he had the backing of Diomedes and enough military experience for the position as well as having spent time at court recently. Regardless, by the end of 214 BCE, Aristarchus was commander of the royal bodyguard and firmly in Diomedes' pocket. With Aristarchus at his back, Diomedes now began dismantling the rest of Mithridates' support network, having several arrested for conspiring with Mithridates in a series of purges in 213 BCE and convincing Seleucus to demote, or fire, several others on the basis of their performance. In their place, Diomedes was quick to institute his own people. Not all of these were Macedonian and, in fact, very few came from Macedonia itself at all. Instead, Diomedes' support network was almost entirely comprised of Greeks and Macedonians living in Syria, many of whom had been there since the time of Seleucus I almost a century earlier.
Attacking Amestris was harder and there was no hope that Diomedes could ever remove her from power. In 213 BCE, he instead began targeting her supporters. Several were arrested as part of the Mithridates purges, largely on forged evidence of their intention to help Mithridates in the coup but his most successful tactic was simply to disgrace them. Scandals of incompetence, impropriety, bribery, and even adultery began to rock the court as official after official was caught out and dismissed. In their place came a whole legion of Greco-Syrian bureaucrats eager to take up the reigns of power for themselves. While Amestris herself kept power, Diomedes effectively disarmed her. While he did so, he made sure to keep her occupied, encouraging the king to send her off on long trips to visit cities and satrapies on the far extremes of the empire. By the time he was done, her own power over the government was neutered and almost every administrative decision was working through Diomedes or his supporters. For now, at least, Diomedes had emerged triumphant. Around 211, Amestris was able to make something of a comeback when she convinced her husband to begin weakening Diomedes for fear that he would launch a coup. Several officials were fired but Seleucus died in 210 BCE before Diomedes could be seriously weakened. With his death and the need of a regent for Antiochus III, Diomedes now stepped in to take control.
