From Wired.com: They Cracked This 250-Year-Old Code, and Found a Secret Society Inside
The master wears an amulet with a blue eye in the center. Before him, a candidate kneels in the candlelit room, surrounded by microscopes and surgical implements. The year is roughly 1746. The initiation has begun.
The master places a piece of paper in front of the candidate and orders him to put on a pair of eyeglasses. “Read,” the master commands. The candidate squints, but it’s an impossible task. The page is blank.
The candidate is told not to panic; there is hope for his vision to improve. The master wipes the candidate’s eyes with a cloth and orders preparation for the surgery to commence. He selects a pair of tweezers from the table. The other members in attendance raise their candles.
The master starts plucking hairs from the candidate’s eyebrow. This is a ritualistic procedure; no flesh is cut. But these are “symbolic actions out of which none are without meaning,” the master assures the candidate. The candidate places his hand on the master’s amulet. Try reading again, the master says, replacing the first page with another. This page is filled with handwritten text. Congratulations, brother, the members say. Now you can see.
For more than 260 years, the contents of that page—and the details of this ritual—remained a secret. They were hidden in a coded manuscript, one of thousands produced by secret societies in the 18th and 19th centuries. At the peak of their power, these clandestine organizations, most notably the Freemasons, had hundreds of thousands of adherents, from colonial New York to imperial St. Petersburg. Dismissed today as fodder for conspiracy theorists and History Channel specials, they once served an important purpose: Their lodges were safe houses where freethinkers could explore everything from the laws of physics to the rights of man to the nature of God, all hidden from the oppressive, authoritarian eyes of church and state. But largely because they were so secretive, little is known about most of these organizations. Membership in all but the biggest died out over a century ago, and many of their encrypted texts have remained uncracked, dismissed by historians as impenetrable novelties.
It was actually an accident that brought to light the symbolic “sight-restoring” ritual. The decoding effort started as a sort of game between two friends that eventually engulfed a team of experts in disciplines ranging from machine translation to intellectual history. Its significance goes far beyond the contents of a single cipher. Hidden within coded manuscripts like these is a secret history of how esoteric, often radical notions of science, politics, and religion spread underground. At least that’s what experts believe. The only way to know for sure is to break the codes.
In this case, as it happens, the cracking began in a restaurant in Germany.
PLYMOUTH divers are investigating the mystery of a wreck site off the Mewstone dating back hundreds of years.
The Mewstone Cannon site, thought to date back to the 18th century, was discovered just off the coast of Wembury in 1968.
Now it has been adopted by Plymouth Diving Centre, based
at Queen Anne's Battery, through the Nautical Archaeology Society's
Adopt-A-Wreck scheme.
The wreck site covers a large area between five and 18 metres
deep, with cannons nearly two metres long scattered across the sea bed
alongside anchors and fragments of olive oil jars which originally stood
over a metre tall.
The site was discovered by visiting divers and was surveyed and
finds noted, but no further work was done until last year, when
non-profit marine research organisation ProMare took up the
investigation.
As part of its SHIPS – Shipwrecks and History In Plymouth Sound –
programme, it carried out a geophysical survey with Plymouth University
to map accurate locations for the cannons before handing its findings
over to Plymouth Diving Centre.
Diving centre manager Lisa McLernon said: "This project will test
our divers' investigative skills, as the cannons are in the same area
as a couple of other wrecks.
"There are various theories about how the site came about.
"It could be a shipwreck destroyed in a storm in the 1700s, with the wood eaten away by marine organisms over time.
"It could be that the cannons were thrown overboard in bad weather in an attempt to save the ship.
"It's exciting that we'll be finding out what really happened all those years ago."
The team will also be creating a diver trail with an easy-to-follow map.
