According to research, queens such as Catherine de’ Medici, Queen Elizabeth I, and Mary Queen of Scots utilised letter locking technology.
In the 16th century, scribes used a complex security system to protect the most essential royal correspondence from snoops and spies. They’d fold the letter and use a dangling strip as an improvised thread to sew stitches that sealed the letter and turned the flat writing paper into its own envelope. To gain access, a spy would have to snip the lock open, which would be impossible to conceal.
