WASHINGTON Some mysteries are such fun you almost don't want to know the truth. That may help explain why people are fascinated with crystal skulls.
Happy to share the spotlight with the latest Indiana Jones movie, the Smithsonian's Museum of Natural History is putting its crystal skull on display starting today.
"People like to believe in something greater than themselves," Smithsonian anthropologist Jane MacLaren Walsh said, and crystal skulls are mysterious and beautiful.
The skulls "are a fascinating example of artifacts that have made their way into museums with no scientific evidence to prove their rumored pre-Columbian origins," she said.
Crystals carved into the shape of a human skull fed the 19th century's need for drama and mystery and its fascination with death. They were supposed to be the creation of ancient Mesoamericans Aztecs, Mixtecs, Toltecs, perhaps Maya.
The skulls were claimed to represent the art and religion of these peoples. Some said the skulls had special, even supernatural, powers.
Scientists say it ain't so.
Nonetheless, the giant crystal skull that mysteriously arrived at the Smithsonian 16 years ago is out of its locked cabinet in Walsh's office and will be on public view until Sept. 1.
Studying this skull led Walsh to extend her investigation into crystal skulls in other museums and to conclude that all are fakes, made in the 19th and 20th centuries.
"In the past, most carved skulls were assumed to be ancient," she said. After all, why would someone go to the trouble of faking one?
Still, she is glad it arrived at her doorstep and prompted the study. "This particular object has told us a whole new story," she said.
The museum's director, Cristian Samper, said people often ask him if there is a real Indiana Jones doing archaeological work.
"I tell them there are several," he said. "People doing field work that is every bit as interesting."
Of the many crystal skulls in museums and private collections around the world, the Smithsonian's is one of the largest, at 10 inches high and weighing 30 pounds. It was mailed to the museum anonymously, accompanied by a note claiming it was of Aztec origin.
It isn't, Walsh said.
The skulls were carved from blocks of quartz sometimes called rock crystal and show the marks of modern carving tools. That means they were not made before the 19th century. The Smithsonian one, she said, seems to have been made between 1950 and 1960.
Indeed, no crystal skulls have ever been found at an archaeological site.
True, skulls appear in Aztec and Toltec art. But, as scientists point out, they always were carved in relief in basalt, a dark rock.
Scientists think the crystal skulls were made in Europe and Mexico, most in the 19th century, a period when there was a thriving market in antiquities, real and fake.
What about their claimed special powers?
Here's what the British Museum has to say:
"Large quartz crystal skulls have generated great interest and fascination since they began to surface in public and private collections during the second half of the 19th century. The British Museum views the skull in its collection as an enigmatic object of great interest but with no supernatural properties."
None of this, though, discourages movies from featuring crystal skulls or museums from joining in. Indeed, in addition to putting its skull on display, the Smithsonian is reporting on the topic in Smithsonian Magazine's July issue and featuring the skulls in a documentary Thursday night on the Smithsonian Channel.
Crystal skulls also are on public view at the British Museum in London and the Musee du Quai Branly in Paris.
