In the Greek village of Pyrgi, the buildings are embellished with xysta, a traditional design featuring rows upon rows of carved geometric shapes on the facades of buildings. Deeply rooted in Pyrgi's cultural history and handed down over generations, the techniques used for creating these precise patterns involve mathematical principles and tools, such as compasses and rulers. Studying the history of xysta, therefore, has given researchers an understanding of how mathematics has been used in this region dating to the medieval period.

There is more academic interest in the tools the Pyrgi people use to construct xysta than in the appearance of xysta.

The people of Pyrgi constructed on their buildings to show an appreciation for mathematics.

The construction of on buildings was first completed in the village of Pyrgi during the medieval period.

Research on techniques used to construct xysta has helped reveal the role of mathematics in the culture of Pyrgi.
