I am wondering if you know anyone who might be able to help me with this
I wrote a while ago about a fascinating project focused on
deciphering the Incan khipu (see below). The basic idea is that they
are collections of knots used in the Incan empire to record
information. It is known that some of them contain numbers, perhaps
recording census data or tax information for the empire. But some
believe that the knots records language -- perhaps histories or
other narratives. Cracking this code would be hugely important, not
to mention interesting, because it would open up the still very
mysterious Incan empire the same way that ancient Egypt has been opened up.
All this is a rather long-winded prelude to my question, which is
whether there are people out there who are working on computational
techniques to decipher ancient scripts, not necessarily the khipu
problem. I am thinking of doing a story on this. Any thoughts or
leads at all would be most appreciated. It would even be a help to
talk to someone who has done cryptography who could explain how the
ancient scripts problem would be similar to, and different from, the
problem of cracking a present-day encryption scheme.
Let me know if you have any thoughts.
SCHOLAR SEES STRANDS OF ANCIENT SECRETS
Author: By Gareth Cook, Boston Globe
CAMBRIDGE - For centuries, the mighty Incan empire has confounded researchers.
The Incas controlled territory up and down the spine of South
America, with a sophisticated system of tributes and distribution
that kept millions fed through the seasons. They built irrigation
systems and stone temples in the clouds.
And yet they had no writing. For scholars, this has been like trying
to imagine how the Romans could have administered their vast empire
without written Latin.
Now, after more than a decade of fieldwork and research, a professor
at Harvard University believes he has uncovered a language of binary
code recorded in knotted strings - a writing system unlike virtually any other.
The strings are found on "khipus," ancient Incan objects that look
something like mops. About 600 khipus (also spelled "quipu") survive
in museums and private collections, and archeologists have long known
that the elaborately knotted strings of some khipus recorded numbers
like an abacus. Harvard's Gary Urton said the khipus contain a wealth
of overlooked information hidden in their construction details, like
the way the knots are tied - and that these could be the building
blocks of a lost writing system which records the history, myths, and
poetry of the Incas.
The theory has Incan scholars abuzz. The discovery of true Incan
writing would revolutionize their field the same way that deciphering
the Egyptian hieroglyphics or Mayan glyphs lifted a veil from those
civilizations. But it also has broader interest because the khipus
could constitute what is, to Western eyes, a very unorthodox writing
system, using knots and strings in three dimensions instead of
markings on a flat expanse of paper, clay, or stone.
"What makes this work so interesting is that what is being expressed
is being conceptualized in such a different way than we
conceptualize," said Sabine MacCormack, a historian of the Romans and
the Incas who is a professor at the University of Notre Dame. "This
is about an expression of the human mind, the likes of which we don't
The only way to prove Urton's theory correct would be to translate
the khipus, which no one has yet done. In his new book, he proposes a
new method for transcribing the knotted strings which he believes
could lead to breakthroughs.
And his work, funded in part by a genius grant from the MacArthur
Foundation, has helped fuel a resurgence of scholarly interest in
khipus. Later this month, the Chilean Museum of Pre-Columbian Art in
Santiago is opening the world's first exhibit dedicated to the khipu.
"We are on the cusp of a very hot period," said Frank Salomon, a
professor of anthropology at the University of Wisconsin who has
studied khipus extensively.
The khipu mystery dates to the early 16th century, when the Incas
were conquered by Francisco Pizarro and the Spanish set about
destroying their culture. The missionaries sent to South America
tried to eliminate all touches of the old gods, including the strange
stringed textiles that the Incas said held their histories.
The Spanish chroniclers often exaggerated, but they did record
histories of tributes and other stories they said were "read" to them
by khipukamayuq - or knot keepers - from strings of knots.
In 1923, researcher L. Leland Locke was able to show that many khipus
recorded numbers like an abacus, with knots in positions representing
the hundred's, ten's, or one's place. He concluded that khipus were
an accounting tool and scholars largely lost interest.
Locke, however, missed many subtleties in the khipus, which could
make them a richer tool for communication, said Urton, whose research
was described in a recent issue of the journal Science, and whose new
book is called "Signs of the Inka Khipu."
The attention to khipus has its roots in insights from Marcia and
Robert Ascher, a husband-and-wife team who began an extensive survey
and analysis of khipus in 1968, and on the observations of Bill
Conklin, a textile specialist at the Textile Museum in Washington,
D.C., who noticed that khipus were spun and tied in surprisingly
complex and varied ways.
Urton is proposing a system for tackling the meaning of the knots.
Each knot, Urton suggests, can be thought of as a series of
decisions, such as whether to make it of cotton or wool, to tie the
knot with a crossing string that begins in the upper left or the
upper right, and to use string that is spun clockwise or counterclockwise.
Not all scholars are persuaded by Urton's ideas.
"I don't see that this proposal arises from the actuality of the
khipus," said Marcia Ascher, an emerita professor of mathematics at
Ithaca College. "I don't see it being shown to fit or explain any of them."
Using money from the National Science Foundation, Urton has
undertaken a comprehensive project to record as many khipus as
possible in great detail, including the binary information he says
could be so important. He hopes to place it all in a single computer
database and give access to other scholars and the public in the
hopes that somebody will see ways to crack the code. He is being
helped by Carrie Brezine, a weaver and database specialist who did
her undergraduate thesis in mathematics.
Last week, Brezine brought in a printout of transcriptions taken from
khipus found recently in a cave overlooking the Lake of the Condors
in northern Peru.
As he sat in his office, surrounded by Andean textiles, he noticed
long strings of numbers that were virtually identical on three of the
khipus - an indication that information was being copied from one to
another, the way medieval scribes copied books by hand.
"It was one of those eureka moments," he said with a boyish grin.
"This is really cool."
