In pre-Roman times, the Samnites moved their flocks seasonally on the ancient paths of beaten grass in search of pastures more suitable for production; this custom was acquired and strengthened by the Romans who maintained the horizontal transhumance on the tratturo (sheep track) between Pescasseroli and Candela, as well as the vertical movement in closerproximity that led to the Matese mountain range. In the vicinity of the roads there were taverns, customs, centres of control placed to collect taxes and to protect the passage of herds, products and people. At the Porta Bojano, a precious epigraphic document of the second century AD is engraved on the right abutment of the structure. Before entering walled town, the imperial rescript recalls a conflict that took place between the authorities of Saepinum and Bovianum with the herdsmen of the imperial flocks who, passing on the sheep track, complained of harassment and of theft of livestock. A clear warning left to remind the reader of the intervention of the praetorian prefects and as a reprimand for the magistrates of the two cities, useful to command respect for the correct procedures in herding practices.
