Mysterious holes in Andean mountain may be an Inca spreadsheet

The recent discovery of thousands of holes arranged in a snake-like pattern on Monte Sierpe in Peru has sparked interest among researchers, who propose that these formations could have served as a monumental accounting device for the Inca civilization. This theory suggests that the Incas utilized these holes for trade and tax purposes, indicating a level of administrative sophistication previously underappreciated. The arrangement of the holes points to a possible accounting function, which aligns with the broader understanding of Inca economic practices. Such findings not only enhance our knowledge of Inca society but also contribute to the ongoing exploration of ancient civilizations' methods of governance and trade management.
