Two Inca Measurement Systems Calculated By Polish Architect

Dr. Kubicka said that until now research on the Inca measurement system was based mainly on 16th and 17th-century chronicles written by colonizing Spaniards, and on their dictionaries of the Quechua language used by the Inca. These sources contain information on anthropometric measures (measures based on human body parts). But the values assigned to them were not known.

Scientists speculated that since the average Inca person was about 1.6 meters tall, Inca ell (arms) could be between 40 and 45 cm. Field measurements were carried out by employees of the Machu Picchu National Archaeological Park together with the 3D Scanning and Modeling Laboratory team led by Professor Jacek Kościuk from the Wrocław University of Science and Technology.

Asked whether her finding has brought anything new to the knowledge of Machu Picchu, Kubicka says the complex was built at one point, in the first half of the 15th century. Therefore, the metrological data she has obtained is not needed to determine, for example, its age.

“On the other hand, the question to observe was whether there were modular differences due to different building traditions of the people who came as labor from different regions of the Inca Empire. At Machu Picchu we have different stonework styles, also used depending on the function of the building or complex of buildings,” Kubicka told PAP.

But it turned out that despite the differences in the construction method, only two measurement systems were used. Kubicka believes that this is evidence that the measuring of the Machu Picchu city plan was supervised by imperial engineers who used their own system of measures.

Further research will determine whether the measurement system identified by Dr. Kubicka was also used in other places in Inca Peru as so far no one has looked into it.

But according to Kubicka, it cannot be ruled out that the units of measurement changed overtime before the advent of the Incas. Perhaps, along with the stone processing technologies borrowed from the Tiwanaku culture, one common system of measures was adopted.

For her analyses, Dr. Kubicka used the cosine quantogram method developed by the British researcher Kendall in 1974 to analyze length measures in megalithic structures. Simply put, it consists of searching for an indivisible unit of measurement (quantum) in a series of measurement data, the multiple of which is the length of individual elements of architecture.
