5,000 years?!? From MSNBC:
Archaeologists in Peru have found a “quipu” on the site of the oldest city in the Americas, indicating that the device, a sophisticated arrangement of knots and strings used to convey detailed information, was in use thousands of years earlier than previously believed. Previously the oldest known quipus, often associated with the Incas whose vast South American empire was conquered by the Spanish in the 16th century, dated from about A.D. 650. But Ruth Shady, an archaeologist leading investigations into the Peruvian coastal city of Caral, said quipus were among a treasure trove of articles discovered at the site, which is about 5,000 years old. snip Shady said no equivalent of the “Rosetta Stone” that deciphered the hieroglyphs of ancient Egypt had yet been found to fully unlock the language of the quipus, but said their existence pointed to a sophisticated, organized society where such information as production, taxes and debts were recorded.Hopefully no one will decipher it and discover I have an overdue bill with the Peruvians.
