Letterlocking is considered a centuries-old technique in which an individual intricately folds a piece of correspondence in order to safeguard the contents from any eagle-eyed snooper. The practice was even tapped by Mary, Queen of Scots, who protected the contents of an 1587 letter to her brother-in-law with a so-called “butterfly lock” seal.
A team of scientists and researchers associated with the Massachusetts Institute of Technology recently revealed that they were able to virtually disclose the contents of locked letters by using X-ray machines, as opposed to cutting the letters apart and destroying historical artifacts.

New Technique Reveals Centuries of Secrets in Locked Letters
M.I.T. researchers have devised a virtual-reality technique that lets them read old letters that were mailed not in envelopes but in the writing paper itself after being folded into elaborate enclosures.

In 1587, hours before her beheading, Mary, Queen of Scots, sent a letter to her brother-in-law Henry III, King of France. But she didn’t just sign it and send it off. She folded the paper repeatedly, cut out a piece of the page and left it dangling. She used that strand of paper to sew the letter tight with locking stitches.
