What the hell's going on here?

It's an example of what the Getty museum offers up weekly as a caption competition. Compare your own witty caption with others at http://thegetty.tumblr.com/post/134300296576/thycaptionbe-you-look-like-hell-you-captioned. The full story is there, too, amusingly told. (If you're on tumblr, or even if you're not, the site for past and future caption competitions is thegetty.tumblr.com

"#ThyCaptionBe is a celebration of modern interpretations of medieval aesthetics. You guess what the heck is going on, then we myth-bust." says the site. Good, old-fashioned fun!
