Hi Professor! Thank you for answering my earlier question about Kleopatra in your books. I have a more history-related question this time: what did a somatophylake actually do? I realized that Alexander’s 7-8 bodyguards were also pretty high ranking generals in their own right who presumably had other work to do… so what would their day to day look like? Do we know if there was a schedule? Was the actual guarding more informal than it sounds? What happened when someone was away?
Somatophylax: Glorified Go-fer or Macedonian Secret Service?
Excellent question, and the short answer is: we aren’t entirely sure what they did.
Also—complicating it further—what they did seems to have changed over time, and from king to king. Especially under Philip and Alexander.
First, some quick terminology for folks:
Somatophylax (sing.)/Somatophylakes (pl.), capped, refers to the 7-man “unit” called the Bodyguard. Which is literally what the word means: bodyguard.
Hypaspists (Hypaspistoi), especially the agema (royal) unit, were also sometimes referred to as the king’s “bodyguard” (somatophylakes, lower case) in combat. (sing. Hypaspistos = “shield bearer”)
The Hypaspists fought together as a unit. The 7-man Somatophylakes did not.
Hetairos (sing.)/Hetairoi (pl.) were the land-owning aristocracy, “companions” (literal meaning) to the king in fighting, hunting, and drinking. They were advisors, and sometimes adversaries. They couldn’t be kings (not Argeads), but were king-makers.
Philoi: Friends (literal), the king’s (informal) inner circle of Hetairoi.
Today, I can use caps versus lower-case/italics to distinguish between a Somatophylax and a somatophylax. But in ancient Greek, that’s impossible because they wrote entirely in what we’d call capital letters. There was no “lower case” until Byzantine authors invented it later. They also didn’t employ (much) punctuation. To make matters worse, our surviving later authors (none of whom lived during Alexander’s age) don’t preserve regularized terms. Arrian might be closest. Moreover, some, like Curtius and Justin, wrote in Latin, not Greek, so they translate the military terminology, and not consistently.
This is why you may see arguments about what the ancient sources actually meant; a great deal of ink has been spilt on military terminology by colleagues such as Waldemar Heckel and Graham Wrightson. But there are a whole bunch of military historians who deal more with these issues than I do. (For the record, I’m a prosopographer and court historian more than military historian—except where those two things overlap, which is not infrequently. So I’m familiar with the issues.) IMO, a Somatophylax is as much a court position as anything military. This is different from the Hypaspists, who are military-battle focused.
What We Do Know
First, I am deliberately not revealing everything I “know,” because some of it I’m working on for the monograph and it’s not been published yet.
Somatophylakes were noble-born Hetairoi, and at least several came of princely houses, not always Macedonian. Philip may have appointed an Epirote royal (Arybbas). Of Alexander’s, Leonnatos was of the royal house of Lynkestis and Perdikkas seems to have come from the royal house of Orestis, maybe even the/a “prince.”
They guarded the inner chamber of the king while he slept. (The Basilikoi Paides, or King’s Boys [Royal Pages] guarded the outer chamber/tent.)
The Macedonian version may owe to Achaemenid Persian influence and its institution as a formal office may date to the reign of Alexander I or his son Perdikkas II. (I'd bet it does.)
In short, this appears to be as much an honorary/quasi-political rank as a functional one. They don't appear to have had any formal training as a bodyguard.
For this reason, it seems that a new king inherited the Seven his predecessor ended with. Or at least, Alexander couldn’t just boot Philip’s Seven when he took the throne. Demetrios, the Somatophylax who was part of the Dimnos Conspiracy, which brought down Philotas and his family, almost certainly was not installed by Alexander. Anger at Alexander’s 330 reforms may have caused him to “snap” and want to replace “his” king’s successor. Ptolemy was elevated to his place after the trial. So, seven years into his campaign, Alexander still seems to have had at least one Somatophylax from Philip, and probably more than that. It’s after this point that he added Hephaistion.
A number of scholars put Hephaistion as Alexander’s first appointment from his personal circle, but he’s listed separately from the Somatophylakes during the Philotas Affair, which occurred in late 330. After Demetrios’s execution, as noted, Ptolemy replaced him. We know only that Hephaistion was a Somatophylax by the 324 appointment of Peukestas. (I argue this in my paper “The Cult of Hephaistion,” btw.)
That gives some tantalizing hints about the “protocol” behind the king’s appointments, but it’s hard to detangle what these actually were unless we knew more for certain about the families of Alexander’s choices—especially the earlier ones. It seems to me that both age and family status had as much to do with it as closeness to the king, which—if indeed they are as much an honorary position as a functional one—should come as no surprise.
What We Don’t Know
Pretty much anything else. Including the details of when and how they served: in some form of rotation(?) and, other than night guard, what they did while on duty.
That said, they do seem to have been in charge of supervising access to the king, at least somewhat. Macedonians expected some level of free approach, but it would have been curated. Random citizen-subjects couldn’t wander into his private office. The Somatophylakes were apparently the last line of defense for the king’s privacy, as well as person. But as we saw with Demetrios, the king might not be able to trust all of them absolutely.
We don’t even know the reason for the odd (not even) number, other than seven having symbolic significance in many societies. In Susa, Alexander promoted Peukestas to the corps as an “extraordinary” eighth. This seems to have lasted until Hephaistion died. There’s no mention that Hephaistion was replaced, so it probably returned to seven. (Alexander had had eight only a year.)
I have jokingly referred to them as the King’s Go-fers, but only in terms of their duties apparently being somewhat eclectic, not in terms of status. Waldemar Heckel places it as (an) endpoint of the Macedonian “cursus honorum” (race of [social] honor).
Any list of (Alexander’s) Bodyguards on the internet is highly problematic in terms of when they became Bodyguards (all place Hephaistion too early, for instance). But for every other Argead king, even Philip, we have an even more incomplete list. At least we can name Alexander’s, even if their year (or even order) of appointment is unclear.
As noted, I am working on a few additional ideas as part of the Hephaistion-Krateros monograph, but they don’t expand that much, tbh. Just more speculative details.
