Forgive me if this is a very elementary question (inspired after watching your TikToks!!) but… I’ve always been curious: what exactly was the role of a secretary in the Macedonian court such that Eumenes could wield so much power and influence, especially during the Successor Wars? Like, to the point that the Chilliarch, the second-in-command to the king himself, would have beef with him? I guess when I think of a secretary, I envision the more stereotypical modern version of them, which is like an executive assistant, or the front desk receptionist, or a customer service agent, which obviously seems to be anachronistic. But I’m just struggling to comprehend what would have made Eumenes, or the role he occupied, such a controversial figure.
First, let me point to an important book by my colleague, Ed(ward M.) Anson, Eumenes of Cardia: a Greek among Macedonians (2nd ed., 2015). It’s a quite excellent discussion of Eumenes’s career, and was actually Ed’s dissertation topic. I reckon, like me, he waited a long while before turning the dissertation into a monograph (even the 1st edition). Alas, it’s expensive. Even I don’t own a copy, as I have access to the university library’s. But I do recommend that folks interested request it via Interlibrary Loan (ILL). Even smaller public libraries offer that service, although you might have to pay a (relatively) small shipping fee.
So, Eumenes is an interesting character in many ways. As you suggest, “secretary” gives the wrong impression. The word in Greek is grammateus, and it can mean any sort of scribe, clerk, records keeper…or the official in charge of the whole royal office: official correspondence, what letters the king actually saw, the keeping of the Royal Journal and other state records, etc., etc. A hugely influential position, his might be closer to what we’d call, in the US, the Chief of Staff.
In my opinion, that was the heart of Eumenes’s dislike of Hephaistion. I said it in my dissertation and still think it’s true. When Hephaistion was made Chiliarch, that put him above Eumenes in administration around Alexander. The Chief of Staff got demoted…and didn’t like it. It’s from Susa onward that the two men seem to clash—at least twice that we know about. (I differ with Ed on this; he thinks it was about personalities while I think it was more political- and status-driven.)
That Eumenes was loyal to Alexander—and the Argead family—isn’t in question. But it wasn’t just Hephaistion he had trouble with. We know he also didn’t like Antipatros—one reason he sided with Perdikkas, even when (his friend) Krateros joined Antipatros. He also had a long-standing family beef with Hekataios of Kardia, and later hated Kassandros (as the son of Antipatros). But he seems to have got on with Olympias and Kleopatra—who he tried to get Perdikkas to marry. Perdikkas took his advice and divorced Antipatros’s daughter Nikaia, which eventually led to his downfall. One can’t escape the sense that Eumenes was touchy. Then again, as I’ve said before, they all were. And he had to put up with being constantly looked down on both as a “mere secretary” and as a Greek among Macedonians. He advanced on Alexander’s favor…which probably made others jealous of him. In fact, I think that’s one reason he took Hephaistion’s promotion hard. He’d worked hard for Chief of Staff, and didn’t like Hephaistion butting in. And if Hephaistion was also of Greek descent (as I’ve argued), both may have had a sense that there was room only for one. Or at least Eumenes may have thought so.
Men in his position weren’t normally entrusted with military commands, but he proved to be surprisingly good and, according to Ed, probably had more army assignments during Alexander’s lifetime than he’s credited with. (He was allied with Ptolemy’s enemy, Perdikkas, remember and Ptolemy was Arrian’s chief military source.) When Perdikkas was elevated to Hephaistion’s position, Eumenes took Perdikkas’s old command, and later, was himself Chilliarch. The infantry seems to have liked/trusted him, and later, he was quite successful at securing Cappadocia. In fact, during the early Diadochi wars, it was his stratagem that defeated Krateros’ army and got him killed (perhaps to his own regret, although I think Plutarch exaggerated that account). He also fought—one-on-one—against Neoptolemos … another of Alexander’s officers he couldn’t stand. And beat him. Neoptolemos was a demonstrated military commander.
So he seems to have defied the usual expectation of what a grammateus could do—and become. He was the highest ranking Greek in Alexander’s army, the only one to really rub shoulders with the Macedonian inner circle.
EDIT: I realized I forgot Nearchos. So Eumenes AND Nearchos were the two top-ranked Greeks at Alexander's court at his death. But if anything, Eumenes had edged Nearchos in place.
