Recent examine reignites the debate about the quipu and reveals that the nodes used by the Incas have been far past conventional accounting
For a long time, the quipu was handled as an administrative software of the Inca Empire, used to file tributes, agricultural shares, harvests, and inhabitants censuses. Now, a new studying suggests that this method of strings, colours, and knots could have functioned as a subtle kind of group and info processing, comparable in some facets to an analog laptop.
The speculation gained traction after a examine accepted in February 2026, when scientists started to analyze not solely the numerical values of the knots but additionally the structure of the quipu. The central level is how the strings are organized in hierarchical ranges, one thing very shut to the tree constructions used right now in databases, digital directories, and file techniques.
This doesn’t imply that the Incas created a trendy laptop, with electrical energy, processors, or binary code. What the examine factors out is one thing else, equally spectacular: the existence of an advanced mental know-how, succesful of storing, classifying, and transmitting data with nice effectivity centuries earlier than computing.
This reinterpretation additionally amplifies the historic weight of the quipu. More than an archaeological artifact, it’s seen as an instance of how pre-Columbian American civilizations developed their very own options to deal with large-scale info.
The hierarchical structure of the strings helps clarify why the quipu is analogous to the logics used right now in laptop science

In the Inca Empire, which flourished in the Andes between the fifteenth and sixteenth centuries, the quipu performed a central position in the administration of a huge territory. Without a consolidated alphabetic writing system, the civilization resorted to foremost strings, hanging threads, totally different colours, twists, and knots in particular positions to file information in a positional decimal system.
The most fascinating side lies in the bodily hierarchy of the object. A foremost string might help hanging cords, which in flip housed secondary threads and new ranges of subordination, forming a logic comparable to folders and subfolders in an working system.
It was this similarity that attracted the consideration of computing researchers. Instead of wanting solely at counting, they started to deal with the quipu as an info structure, that is, a structure succesful of organizing information in a number of layers in a scalable method.
Researchers took the Inca mannequin to languages like C++ and Python and created prototypes impressed by the logic of the nodes
One of the most mentioned approaches got here from laptop scientist Richard Dosselmann, who studied the quipu alongside Edward Doolittle and Vatika Tayal. Instead of merely attempting to decipher the artifact, the group proposed modeling its functioning with up to date instruments.
The workforce translated the logic of the cords into languages like C++ and Python, even creating a digital format straight impressed by this Andean structure. In observe, this opened up house for the growth of functions that simulate spreadsheets, file techniques, and encryption strategies primarily based on the group of the nodes.
The prototypes present an essential benefit of the mannequin. Information may be added with out requiring a full reorganization of the system, making the structure linear, scalable, and helpful for massive plenty of information, corresponding to inventories and censuses.
Another level that caught consideration was the chance of concealing meanings via the easy reorganization of the cords at totally different ranges. Even although the Incas in all probability didn’t suppose of this as encryption in the present sense, the quipu presents traits that permit to shield or cover info primarily based on the very association of the information.
Research by Marcia Ascher, Robert Ascher, and Sabine Hyland point out that the quipu could have saved numbers, reminiscence, and even parts of language
The studies on the quipu didn’t begin now. Decades in the past, researchers like Marcia Ascher and Robert Ascher had already demonstrated the excessive diploma of mathematical sophistication of the system, exhibiting that the Incas mastered an extraordinarily exact kind of file primarily based on decimal locations.
In current years, the dialogue has advanced past numbers. Researcher Sabine Hyland argues that sure combos of coloration, place, and sort of knot could carry semantic meanings, not simply portions.
There are research suggesting the existence of up to 95 doable markers, succesful of representing sounds, ideas, or classes. If this speculation is confirmed, the quipu shall be even closer to a kind of writing or a advanced coding system.
This chance modifications the standing of the object. The quipu would stop to be simply an accounting software to even be understood as a reminiscence instrument, narrative file, and communication software, one thing far more subtle than beforehand thought.
The comparability with the Antikythera mechanism helps to reposition the Incas at the heart of the historical past of historic know-how
When the quipu is known as an analog laptop, the inevitable comparability arises with the Antikythera mechanism, usually cited as the world’s first analog laptop. The distinction is that whereas the Greek artifact labored with gears and astronomical calculations, the Inca system relied on fibers, colours, twists, and knots.
Both circumstances present very totally different paths to the similar human goal: to symbolize, manage, and manipulate advanced info. This realization forces the history of technology to transfer away from the conventional axis, often targeted on Europe and the Middle East.
The quipu reinforces that pre-Columbian Americas additionally produced authentic and subtle options to the downside of information storage. Instead of screens, circuits, and steel, the Incas resorted to easy supplies to construct a system of huge logical effectivity.
Therefore, calling the quipu merely a counting software appears inadequate. The time period laptop could even generate controversy, however the expression millennial info system aptly describes the relevance of this legacy.
Why the quipu continues to arouse fascination and skepticism at the similar time amongst archaeology, historical past, and computing
The fascination surrounding the quipu comes exactly from what it has but to totally reveal. The extra researchers take a look at its logic with trendy instruments, the clearer it turns into that the Incas developed a system far past mere counting of items and folks.
At the similar time, there may be warning amongst specialists. Calling this artifact a laptop could sound exaggerated to those that affiliate the phrase solely with electronics, however ignoring the complexity of the quipu additionally impoverishes the historic dialogue.
The most balanced strategy is to acknowledge that we face an extraordinary info know-how for its time. About 600 years in the past, the Inca Empire was already dealing with information hierarchy, scalability, and coding in a manner that nonetheless surprises archaeologists and laptop scientists.
And you, does it make sense to name the quipu an analog laptop, or does this time period stretch the comparability with present know-how too far? Leave your remark and be part of the debate, as a result of this discovery straight impacts how the historical past of science is often informed.
