Gromatici (from Latin groma or gruma, a surveyor's pole) or agrimensores was the name for land surveyors amongst the ancient Romans. The "gromatic writers" were technical writers who codified their techniques of surveying, most of whose preserved writings are found in the Corpus Agrimensorum Romanorum.
