In an age when computers process immense amounts of information by the manipulation of sequences of 1s and 0s, it remains a frustrating mystery how prehistoric Inka recordkeepers encoded a tremendous variety and quantity of data using only knotted and dyed strings. Yet the comparison between computers and khipu may hold an important clue to deciphering the Inka records. In this book, Gary Urton sets forth a pathbreaking theory that the manipulation of fibers in the construction of khipu created physical features that constitute binary-coded sequences which store units of information in a system of binary recordkeeping that was used throughout the Inka empire. Urton begins his theory with the making of khipu, showing how at each step of the process binary, either/or choices were made. He then investigates the symbolic components of the binary coding system, the amount of information that could have been encoded, procedures that may have been used for reading the khipu, the nature of the khipu signs, and, finally, the nature of the khipu recording system itself—emphasizing relations of markedness and semantic coupling. This research constitutes a major step forward in building a unified theory of the khipu system of information storage and communication based on the sum total of construction features making up these extraordinary objects.

Inka khipus--spun and plied cords that record information through intricate patterns of knots and colors--constitute the only available primary sources on the Inka empire not mediated by the hands, minds, and motives of the conquering Europeans. As such, they offer direct insight into the worldview of the Inka--a view that differs from European thought as much as khipus differ from alphabetic writing, which the Inka did not possess. Scholars have spent decades attempting to decipher the Inka khipus, and Gary Urton has become the world's leading authority on these artifacts. In Inka History in Knots, Urton marshals a lifetime of study to offer a grand overview of the types of quantative information recorded in khipus and to show how these records can be used as primary sources for an Inka history of the empire that focuses on statistics, demography, and the "longue durée" social processes that characterize a civilization continuously adapting to and exploiting its environment. Whether the Inka khipu keepers were registering census data, recording tribute, or performing many other administrative tasks, Urton asserts that they were key players in the organization and control of subject populations throughout the empire and that khipu record-keeping vitally contributed to the emergence of political complexity in the Andes. This new view of the importance of khipus promises to fundamentally reorient our understanding of the development of the Inka state and the possibilities for writing its history.

The Inka Empire stretched over much of the length and breadth of the South American Andes, encompassed elaborately planned cities linked by a complex network of roads and messengers, and created astonishing works of architecture and artistry and a compelling mythology—all without the aid of a graphic writing system. Instead, the Inkas' records consisted of devices made of knotted and dyed strings—called khipu—on which they recorded information pertaining to the organization and history of their empire. Despite more than a century of research on these remarkable devices, the khipu remain largely undeciphered. In this benchmark book, twelve international scholars tackle the most vexed question in khipu studies: how did the Inkas record and transmit narrative records by means of knotted strings? The authors approach the problem from a variety of angles. Several essays mine Spanish colonial sources for details about the kinds of narrative encoded in the khipu. Others look at the uses to which khipu were put before and after the Conquest, as well as their current use in some contemporary Andean communities. Still others analyze the formal characteristics of khipu and seek to explain how they encode various kinds of numerical and narrative data.

Unique, thought-provoking study discusses quipu, an accounting system employing knotted, colored cords, used by Incas. Cultural context, mathematics involved, and even how to make a quipu. Over 125 illustrations.

This book begins by proposing a theoretical model that reconciles orality-literacy studies and media theory in order to avoid the specious dichotomization of societies into those with and those without writing. The more relevant issue is the way in which a given society distributes semiotic functions among the various media that it employs and the forms of economic and political integration within which such media function. This theoretical model then informs a history of the Andean khipu from pre-Columbian times through the first 120 years of the colonial period. The first half of the book examines early Andean media and their socioeconomic and political contexts, culminating with the emergence of Wari and subsequently Inca khipu. The second half of the book documents and analyzes the continued use of khipu by indigenous individuals and communities in their interactions with Spanish officials, chroniclers, and priests. The study corrects many common misconceptions, such as the alleged mass destruction of khipu in the late sixteenth century. Even more importantly, it highlights the dialogue that occurred in the colonial period between the administrative and historiographic discourses of alphabetic Spanish and those of native Andean khipu genres.

Breaks new ground with a close ethnography of one Andean village where villagers, surprisingly, have conserved a set of ancient, knowledge-encoded cords to the present day.
