Discovered in 1992 thanks to four excavation campaigns carried out by Marina Mazzei between 1992 and 1997 for the Archaeological Superintendence of Apulia, the hellenistic domus «of the mosaic of lions and panthers» of Arpi (Foggia) constitutes one of the few known examples of the use, in the domestic space in Southern Italy, of a decor in structural style. The recent restoration of the fragments for their exhibition in a dedicated room of the Civic Museum of Foggia, inaugurated on 17th December 2015, was undertaken in the frame -work of a scientific collaboration between the Archaeological Superintendence of Puglia, the Centre Jean Bérard and The University of Salerno. The aim was to lead a study of this regional variant of the structural style in Apulia, between the time of Pyrrhus and that of Hannibal. The information provided on the raw materials and technique of these wall paintings, by the autoptic examination of the fragments imitating marbles from two pieces of representation and by the archaeometric analyses carried out on 35 samples, makes it possible to place this production in a set of regional achievements attested mainly by funerary contexts.
