Atlas Obscura: How Scholars Cracked a Medieval Alchemist’s Secret Code
Online magazine features Institute fellows Megan Piorko and Sarah Lang, who helped decode a puzzling Latin cipher.
Science History Institute fellows Megan Piorko and Sarah Lang are featured in an Atlas Obscura article about a Latin cipher written by 16th- and 17th-century alchemist and physician Arthur Dee.
