New archaeological excavations of ancient floors in the house of Pompeii reveal enigmatic images that appear to pay tribute to the urban planners of the day.
Researchers believe excavations uncover the first ever depiction of the Roman land surveyors' clever measuring tool, known as a groma.
Excavations are taking place in the Casa di Orione, or the House of Orion, amid the remains of the ancient city in the province of Naples, southern Italy.
This image appears to be a depiction of a primitive badge or logo of the group and principles of Roman land planners, known as Agrimensores

As well as two mosaics representing Orion, the hunter in Greek mythology, three enigmatic images appear to reference the Roman Agrimensores, the name given to Roman ground surveyors and planners.
The images were created by embellishing cement paving stones within the house with small stones or tiles.
One such example features a square inscribed inside a circle, which is cut by two perpendicular lines, one of which represents the longitudinal axis of the house.

Agrimensores were the land surveyors of the ancient Romans.
They were technicians in charge of the centuriations (division of the lands) as well as town and aqueduct planning.
The role of the Agrimensores was seen to carry out surface survey and setting out grids for the formation of a town.
They were otherwise known as Gromatici for their
