A Trial Excavation at Monte d'Irsi, Basilicata
Monte d'Irsi is located approximately 6·5 km. east-southeast of the town of Irsina and 4 km. due west of the village of Santa Maria d'Irsi in the region of Basilicata. The archaeological site sits on the crown of an irregularly shaped plateau at around 480 m. above sea level; the land drops away steeply in all directions and the hill-sides are heavily eroded by stream beds which feed into the two major rivers in the area, the Bradano and the Basentello (Figs. 1 and 2 and Pl. XXVII, a). M. d'Irsi lies about 7·5 km. north-west of the confluence of the two, and since it is the highest point for 6 or 7 km. round about, forms an imposing feature of the landscape. No doubt it is this fact, connected with the proximity of M. d'Irsi to the very important Bradano valley (3 km. distant) that made the M. d'Irsi plateau a prime candidate for settlement even in prehistoric times and presumably in times of stress.
