This looks like it's likely a parody of some piece of artwork, but it's not The Last Supper.

I know I've seen it somewhere before... it's a "The Death of..." piece, I'm fairly certain, but I just can't come up with the name.

It's just been too long, can't remember.

"The Death of Socrates" looked the closest to various "The Death of..." images I searched, but I still think this post looks more similar to The Last Supper to be tagged as such.

The Last Supper features:
- People that are seated at a long table indoors
- Obvious room perspective with vanishing point on central figure (Jesus)
- Additional 12 men dining with central figure
- Four background pillars along the back wall, with pillars along the side
- Reserved gathering of solemn and surprised people

This post features:
- People that are either seated at, standing by, or sprawled out on a long table indoors
- Obvious room perspective with vanishing point on central figure (Reimu)
- Additional 21 women (counting Shanghai) dining with central figure
- Four background pillars along the back wall, with pillars along the side
- Lively party of rowdy drunkards and disdainful onlookers

It's Romans during the Decadence by Thomas Couture.

Ah, I had another image in my mind, involving an angel floating above the dying man.
That's irrelevant, of course. Great Work on finding that, man!

Very nice work, eidolon. And thanks, guys, for pointing out my error-- I stand corrected and appreciate learning something new!
