Groma

Definition

The groma was a crucial surveying instrument used in ancient Rome for laying out roads and buildings with precision. It consisted of a vertical staff with horizontal crossbars attached at right angles, allowing surveyors to create straight lines and right angles, which were essential for Roman construction techniques. This tool played a significant role in the Roman engineering prowess, enabling the establishment of their iconic infrastructure such as roads, aqueducts, and buildings.
