What does it say about the Central Intelligence Agency that its agents can crack the secret codes of enemy nations but can't unravel a coded sculpture sitting outside their cafeteria window?
It says, perhaps, that artist Jim Sanborn, who created the cryptographic sculpture named Kryptos that sits on CIA grounds, could have a career in covert operations if he ever grows tired of stumping the experts.
It's been nearly 15 years since Sanborn installed the 12-foot-high, verdigrised copper, granite and wood sculpture inscribed with four encrypted messages at the CIA's Langley, Virginia, headquarters in 1990. And it's been seven years since anyone made progress at cracking its code.
But publication of the novel The Da Vinci Code has renewed interest in solving the puzzle because author Dan Brown made two veiled references to Kryptos on his book's dust jacket. Brown's publisher sponsored a contest around the references, and Brown has hinted that his next book, which takes place in Washington, D.C., may feature the sculpture in some way......
"We have lots of different theories that we're chasing down," Dunin said of her band of sleuths, which includes some CIA employees. "But there's no way we'll know whether we're on the right track until something comes loose."
Kryptos isn't a complete mystery. Parts of it have been solved.
In 1998, CIA analyst David Stein cracked three of the four coded messages after diddling over the problem with paper and pencil for about 400 hours spread over many lunch breaks. Only his CIA colleagues initially knew of his success, since the agency didn't publicize it. A year later, California computer scientist Jim Gillogly gained public notoriety when he cracked the same three messages using a Pentium II.
