  In recent archaeological investigations of Pompeii Regio V houses, a series
of new, rather enigmatic images on the floors of the entrance and of the
Tablinium of the so called House of Orion have been unearthed. These images are
presented here together with a tentative interpretation, which is based on a
clear analogy of their content with the illustrations of the codexes of the
Gromatics, the Roman agrimensores
