And I am sure we will have a retelling of 9/11 in mythological terms any day now. (... for all I know there might be one already?)
I would say that is impossible, at least not in the way I was suggesting. Oh, it's certainly possible to give a supernatural explanation of 9/11, or one using mythological tropes, but it's way too recent past to actually
be mythology. I have vivid recollection of hearing about the first plane crash while driving home after class, and watching CNN in horror for a few hours, and worrying about a friend who worked in downtown New York. I remember following the ever changing death counts on the news. My children, or their children, could form myths about it. For me it's just a part of my life, and even if someone manages to demonstrate that the twin towers were actually taken down by Zeus, that won't make it mythology.
Hotel Astarte works because the Great Depression is known to us - at least those of us who are not actually historians - mostly as a myth. We only hear it from secondary, teritary, and further removed sources. We have fragments of knowledge about it that don't combine together into a coherent picture, because there are too many gaps and probably too many contradictory accounts feeding into our knowledge. We can't tell apart what really happened from scenes from movies such as
Grapes of Wrath. And most importantly, we grew up on these myths. They may be based on reality, but for all practical reasons they are just cultural background the same way the Trojan war was. I'm generalizing over myself here, but I'm sure that's true for most people here, at least of my generation and younger.
9/11, the (first) Gulf War - even the second World War, those are too recent history to be myth, because either my life was touched directly by them, or I know people who were. The Great Depression falls just beyond the cusp (it's not just timeline, by the way, it's also geography -
Last Call works for me because I've never been to Las Vegas, and everyone I know who had only went for very short visits and didn't look beyond the surface).
Anyway, I'm not sure if this post has gone off-topic or not, but it's probably time to end it regardless.
