In the surroundings of Milan there were no stone nor clay pits: the pieces of demolished or ruined constructions were thus often reused for the buildings of the following époques. For example, they were integrated into the city walls or were used for the buildings’ foundation. The funerary epigraphs made no exception. For example, in the IV century A.D., when the city of Milan was enlarged, many of the epigraphs in the pagan necropolis were inserted in the city walls.
