A more thorough explanation:

MENSOR

A mensor (men-sor) is a person who measures land and surveys it. The word comes from the Latin word "metiri" which means "to measure". In Roman law, a mensor was an important person who helped determine the boundaries of land and property.

For example, if a farmer wanted to know the exact size of their land, they would hire a mensor to measure it. The mensor would use tools like a measuring tape or a theodolite to determine the exact boundaries of the land. They would then create a map or a plan of the land, which would be used to settle any disputes or legal issues related to the property.

In ancient Rome, a mensor was also responsible for measuring public land and creating maps of the city. This was important for urban planning and for ensuring that everyone had access to public resources like water and roads.

Today, surveyors and land measurers still play an important role in determining property boundaries and creating maps. They use advanced technology like GPS and drones to get accurate measurements and create detailed maps of the land.

The examples illustrate how a mensor is a person who measures land and creates maps. They use tools and technology to get accurate measurements and ensure that property boundaries are clearly defined. In ancient Rome, a mensor was an important figure in ensuring that public resources were fairly distributed. Today, surveyors and land measurers continue to play an important role in urban planning and property management.
