So… what goes next to the masterpiece?

I’ve often wondered this in large galleries. Usually, when it’s the case that you’ve got something like Guernica (wrongfully) at the Reina Sofia in Madrid, you can place the work by itself and everyone is happy because we can absorb to our heart’s content. Lesser works be damned.
But what happens when it’s a something smaller like Bal du moulin de la Galette by Renoir? You can’t take up a whole museum wall with that (it’s only about 1.5x1m.) As I saw at the Musée d’Orsay, apparently you go through the entire collection and try to find that awkward best friend of the masterpiece to stick next to it. Yeah, it may not really know what to do and it will often take its queues from the bigger work next to it, but that’s okay. Sure, it may get some occasional glances from those checking out the masterpiece, but it won’t really know what to do with them
It almost makes you want to feel bad for it, but at the same time, that lesser work has some hard lessons to learn. Maybe it needs to strike out in the world. Maybe go off to America where the playing field is a bit more even. Maybe someday it will walk in the door of any American West Coast museum and say, “Bitches, I’m a fucking Renoir! Showcase my canvas properly!” And then yes, it will get a spot and not have to deal with all the attention that whore, Bal du moulin de la Galette was getting, but this has to be earned. It wasn’t born with the good looks of a masterpiece.
