A coded letter penned by the King of Spain in the 16th century has been deciphered by a team of researchers. Charles V reportedly sent the mysterious missive to his French ambassador in February of 1547. The curious letter contains three paragraphs of readable text along with portions which are comprised of peculiar letters and symbols that constituted a code that only the king's proverbial inner circle could understand. At some point in the centuries since the message was sent, it wound up in the Stanislas Library in the French city of Nancy. Remarkably, the intriguing note went unnoticed in their archives until two years ago, when it was unearthed and inspired a group of researchers to find out what the code might say.
