Sooo, this is the result of me coming up with something very silly indeed. There is the well-known myth of the Seven Against Thebes and the Aeschylus play based on it. It’s all a follow-on from Oedipus doing his thing and the familial fallout that results. The upshot is that an army raised by the Seven, led by Polynikes, the son of Oedipus, attacks Thebes, which is being ruled by Eteokles, Polynikes’s brother, who defaulted on his promise to share rule with his brother. Hence the army. As per usual in Greek myth, nearly everyone ends up dying, the gods interfere, etc.
Anyway, what would the modern equivalent be? And if you only need Seven to take Thebes, how many would you need to take, say, Cambridge? Or London? The first thing to work out here is what the population of the Thebes the Seven attack is. The myth is nominally set a generation or so before the Trojan War, so the Thebes we’re interested in is Mycenaean Thebes, as opposed to Classical or Hellenic Thebes. Mycenaean Athens is estimated to have had a population of about 10,000-15,000, but that’s very much a maximum – Athens had very fertile territory in Attica and not much local competition for the land, so could always support a larger population than pretty much any other city in Greece[1]. Thebes, whilst being one of the oldest cities in Greece and historically dominant in its region of Boeotia, faced a lot more competition, so its resource base and population would have been correspondingly smaller. I’ve not been able to find any actual numbers on its population in the Mycenaean era, but I’m reliably informed that 5,000 is probably in the right ballpark. For the sake of making some maths easier, let’s actually call it 4,900.
What does this mean in modern terms? Pretty much that the Seven would be a good match for the combined forces of St Davids (1,800 people) and St Asaph (3,400 people). The Seven Against Saintly Welsh Cities isn’t quite as snappy, is it? Equally, the Seven would probably manage to conquer the Isle of Arran (4,600 people), but would probably be unable to take Kirkwall, Lerwick or Stornoway (all in the 8,000-10,000 range). In other words, the Seven would not exactly be terrorising the towns of Britain these days. Even modern Thebes, which isn’t all that major a town these days, would be beyond them, with over 20,000 people, though they could have a good go at some of the smaller Greek islands – Ithaca, Ios, Amorgos, Milos and Samothrace would all be vulnerable.
But let’s assume we can clone the Seven. How many would we need to take out some modern cities, if we assume the Seven scale linearly with population? If the Seven can take Thebes, with assumed population 4,900, that means any one of them is worth 700 population[2]. So, to return to modern Thebes, we’d need to rewrite the legend as the Thirty Against Thebes[3]. That’s not too bad. Thirty’s not a ridiculous number. And it alliterates, so, if anything, that makes it better than the original.
However, as I said, modern Thebes is not the regional powerhouse it once was. OK, it’s still the largest city in Boeotia, but it’s a small provincial market town, not one of the main players for control of all Greece. If we want a more reasonable modern Greek comparison to ancient Thebes, we’re probably looking at Patras (170,000), Larissa (145,000) or Heraklion (140,000). Which would give us the Two Hundred Against Heraklion or Against Larissa. Or the Two Hundred And Fifty Against Patras. Those numbers aren’t too bad and sound suitably legendarily epic, though the inflation from 7 to 250 gives you some indication of global population growth in the last 3,000 years…. If they wanted to menace Athens itself (3,000,000), though, we’d be talking about The Four Thousand Three Hundred Against Athens. Which is starting to get a bit silly. If the Seven were aiming to take out Greater London (9,000,000), as an example of a big world city, we’d be nearing The Thirteen Thousand Against London[4]. And, if they were feeling incredibly megalomaniacal and tried to take the whole of Greater Tokyo, the most populous metropolitan area in the world (37,000,000), we’d be looking at The Fifty-Three-Thousand Against Tokyo. We could test this empirically by sending the entire population of St Kitts and Nevis in a long-overdue expansionist war against Tokyo. In the interests of science, naturally.
To sum all that up: the Seven wouldn’t be much use nowadays – they could threaten isolated islands and small provincial towns, and that would be about it – but if we could clone them at will, we’d end up with the most cost-effective urban warfare force in the world. That’s what I like: an impractical solution to a problem that doesn’t need solving. Well done me[5].
[1] This is one of the main reasons Athens was historically so dominant in Greece. Sparta, one of its big rivals, achieved something similar by absorbing Messene early and turning its population into helots. More people = bigger army, pretty much. And when everyone’s fighting with more-or-less the same equipment and tactics, sheer quantity is what’s likely to win.
[2] Yes, I know the Seven actually had an army and weren’t attacking Thebes single-handedly, but it’s more fun to assume it’s just those seven guys. If you’re really bothered about it, we can assume that each marginal One of the Seven spawns with some retainers or something. It doesn’t really matter.
[3] Technically, the Thirty-Two-And-A-Half Against Thebes, but we’re all friends here and I think we can be generous on the rounding.
[4] Incidentally, this gives you a good idea of how good the Seven were. If you wanted to actually besiege and potentially assault the whole of Greater London, you’d need a lot more than 13,000 troops. Because the circumference of cities doesn’t scale linearly with population (and thus area). But, we’re assuming the Seven, as Greek heroes, can sort of ignore that problem. Zeus/Athene/Poseidon/Aphrodite/Ares/Apollo/any or all of the above and all the others will intervene and sort it out.
[5] Also, feel free to come up with your own punchline to the title. I thought of ‘Because Seven Became Nine Thousand’ or ‘Because CLONES’. I didn’t say they were good. There’s a reason I left them out of the title.
