Amsterdam, September 7, 2020 – A modern examine by a team based at the University of Bologna, published in the Journal of Archaeological Science, has drop new mild on the Minoan program of fractions, one of the exceptional enigmas tied to the historic composing of quantities.

About three,five hundred a long time back, the Minoan civilization on the island of Crete developed a composing program composed of syllabic symptoms, named Linear A, which they at times applied to inscribe choices at sanctuaries and adorn their jewelry, but mainly assisted the administration of their palatial facilities.

These days, this script stays mostly undeciphered and incorporates a sophisticated program of numerical notation with symptoms that indicated not only total quantities, but also fractions (these types of as 1/two, 1/4, 1/eight, and many others.). Although the total quantities were being deciphered decades back, scholars have been debating on the specific mathematical values of the fractional symptoms.

Principal Investigator Silvia Ferrara, Professor of the Division of Classical Philology and Italian Scientific studies of the University of Bologna, mentioned: “We aimed to resolve the dilemma by way of a lens combining different strands of analysis, very seldom tied together: shut paleographical evaluation of the symptoms and computational techniques. In this way we realized that we could obtain information from a new point of view.”

The associates of the European Exploration Council challenge INSCRIBE (Invention of Scripts and their Beginnings), Michele Corazza, Barbara Montecchi, Miguel Valério, and Fabio Tamburini, led by Dr. Ferrara, used a system that brings together the evaluation of the indicator styles and their use in the inscriptions together with statistical, computational and typological procedures to assign mathematical values to the Linear A symptoms for fractions.

The team very first studied the policies that the symptoms followed on the clay tablets and other accounting paperwork. Two complications experienced so significantly challenging the decipherment of Linear A fractions. Very first, all paperwork containing sums of fractional values with a registered full were being damaged or tricky to interpret, and next, they contradicted makes use of of particular symptoms, which propose the program changed about time. Consequently, the starting premise experienced to depend on paperwork concentrated to a precise interval (ca. 1600-1450 BCE), when the numerical program was in coherent use across Crete.

To investigate the probable values of every fractional indicator, the team excluded unattainable results with the support of computational techniques. Then all probable remedies – practically four million – were being whittled down also evaluating fractions that are common in the background of the earth (e.g., typological information) and making use of statistical checks. Ultimately, the team used other procedures that deemed the completeness and coherence of the fractions as a program and in this way the most effective values were being determined, with the minimum redundancies. The outcome, in this scenario, was a program whose lowest fraction is 1/60 and which shows the capacity to signify most values of the sort n/60.

The program of values instructed by the Bologna team has yielded more significant implications.

The final results explain how the Linear B script, adopted by the later Mycenaean Greek society (ca. 1450-1200 BCE) from Linear A, reused some of these fractions to specific units of measurement. The new final results propose that, for instance, the Linear A indicator for 1/10 was tailored to signify a ability device for measuring dry products and solutions which was, in change, 1/10 of a much larger device. This clarifies a historic continuity of use from fractions to units of measurements across two different cultures.

This analysis aims to demonstrate that traditional techniques and computational models, when applied in synergy, can assistance us make remarkable development into explaining some unresolved challenges tied to historic scripts that are however undeciphered.
