The Dark Ages are not selection-bias

A kerfuffle has broken out on X upon Crémieux' memetic chart of what the Louvre displays to tourists. tl;dr it's Greek, with a bit of Roman and then a stark dropoff. The High Middle Ages get displayed again and then modernity.

That arrogant "History For Atheists" guy pipes in, such that the Cruel Sardaukar must spank him. Bryan Ward-Perkins, you'd think, should have been read aloud to the man, perhaps with hand-puppets. Now apparently O'Neill finds his buttcheeks insufficiently-rouged: this quaint “dark ages” designation by that insufferable data bro clownboy.

A descendant of Niall might feel that his family back in Eire weathered this storm fine. I can imagine an Arab saying similar - or, later, a Damascene. For the rest of us, Rome's collapse was a disaster. And not just the West: the Greek world contracted (only surviving after re-"Roman"ising) and today Iranians too will, if asked, or not asked, tell you of "two centuries of darkness".

The rot had already started, as the Sardaukar details. One interesting point is how Justinian was able to dislodge the Vandals with a smaller force. Some of that is Belisarios' skill. Some of that is because, economically, the middle class - including soldiers - could push for higher wages in the wake of Yersinia. We might believe an incremental improvement in military efficiency and a healthier soldiery. We do not see any such improvement in art. And certainly not in the sciences: a lot of Greeks and Syrians were retreating to flat-earth theory (Latins, being stubborn, stayed round-earth mostly). There's no way that theory helped out with naval tech or its knock-on, trade.

With fewer men and worse maps, the Arabs became more important as intermediaries, because they didn't need maps where they lived. That's where Henri Pirenne might jump in.

Now: where selection-bias might be cogent, is in the choice of Greek/Gaulish wares over principate-Roman in the Louvre. The French are, historically, taught to be descendates of the Gauls so their muséa may prefer that era. Also possible is that Julius Caesar trashed the place so hard it somewhat suffered its own mini Dark Age. Although here I am unsure. If I were running this museum I might play up the western "Roman empires" especially their Constantine III, as well as their rôle in staging reconquistas of Britain. We've recently mentioned Domitian II.
