1st hidden messages #greekhistory

You’ve probably heard of the idea of steganograph or the practice of concealing messages or information within other non-secret text, data or objects during ww2 like invisible ink, people wearing morse code in a knitting pattern on their clothes, maps made of silk hidden inside clothes, or even more recent cases like Jeremiah Denton who was helpd captive during the vietname war in 1966; he used his eyes to blink Morse code during a tv press conference spelling out "T-O-R-T-U-R-E". letting the people back home what was really going on in the prisons. It is recorded by Herodotus in the 5th century BC that Histiaeus ("his-tee-AY-us." )of the ancient Greek city of Miletus ( "my-LEE-tus." )shaved his servants and then tattooed a message on his scalp. The idea was to wait until his hair grew back and then forward a message warning of impending attack by the Persian army. #historydocumentary #steganography #JeremiahDenton #Histiaeus #Herodotus #history #facts #first #secretmessages #vietnam
