Have You Seen This Man?

Probably, and looking exactly like this. Warner Sallman's 1940 oil painting "The Head of Christ" is believed to be the most reproduced religious work of art. It's been copied a billion times, if you include lamps, clocks and calendars.

"For the love of God, what are you going to do next?" That's what the mother of British artist Damien Hirst reportedly exclaimed after learning about his latest project, a bejeweled 18th-century human skull that's cast in platinum and covered in more than 8,600 diamonds. So Hirst—who bought the jewels with the proceeds of past adventures in art such as a pickled shark—called his 1,106-carat cranium "For the Love of God." Considering that the piece is said to have cost $23.5 million to make, there's obviously a bit of irony in the title, too. The piece is on display at London's White Cube gallery and on offer for $100 million. If "God" finds a buyer—perhaps a rapper looking for the ultimate bling?—it'll be the most expensive contemporary artwork ever.

Museums have a way of making everyone feel insignificant and inferior. To wit, a glossary of terms to help you while you're shopping for that new Matisse:

GALLERINAS: The lovely young ladies, usually wearing simple black dresses, who attend the elegant reception desks at high-end art emporiums.

GALLERIST: A term, popular in Europe, that makes a gallery owner seem like some kind of artist, creating meta-artworks by scheduling shows.

INSTALLATION ART: A lot of weird stuff—or maybe just a few somber items—put in an empty room, allegedly with great significance.

THE LONG MARCH: Occurs for artsies every 10 years (2007 is one of them) when the Venice Biennale, Documenta (in Kassel, Germany) and Sculpture Münster (also in Germany) mega-exhibitions take place in the same summer.

M.F.A.: Graduate degree, but a career ticket only if it's been issued by Yale, UCLA or CalArts.

POSTMODERNISM: Modern art's idea of "progress" is over, so it's time to play dress-up in the granny's attic of art history.

CURATOR: Formerly, a scholar in charge of caring for an art collection; currently, an impresario of exhibitions who possesses a large Rolodex.
