perustum

Perustum is a term that originates from the Latin word "perustum," which means "foundation" or "base." In ancient Roman architecture, a perustum was a large stone or block that served as the foundation for a building. It was typically placed at the center of the building's footprint and was used to ensure stability and alignment. The perustum was often made of a durable material such as marble or granite and was carefully positioned to support the weight of the structure above it. In some cases, the perustum could also serve as a decorative element, with intricate carvings or inscriptions. The use of a perustum was a common practice in Roman architecture, and it can still be seen in many ancient Roman buildings and ruins today.
