An Example of Geographic Network Analysis: The Case Study of the Fortore Valley (Molise and Apulia, Italy)

Abstract Today, the Fortore River is the geographic and administrative boundary between the regions of Molise and Apulia. In the past decade, scholars have debated Fortore’s role during the pre-Roman and Roman periods, specifically focusing on how this physical boundary may have influenced the interaction and connectivity between Samnium (modern-day Molise) and Daunia (modern-day northern Apulia). Both ancient literary sources and archaeological finds indicate the situation is complicated, and it is challenging to locate the geographical and cultural borders, especially in the pre-Roman period. This article suggests a model to understand the past interaction between the two modern-day areas of Macchia Valfortore (Molise) and Carlantino (Apulia). These sites were in the proximity of the Fortore River, and an investigation of material culture in both locations revealed a complex and diverse society between the sixth century BC and the first century BC. The small-scale spatial networks constructed help to explain the interchange dynamics between the two districts and, furthermore, how each of them related to the ancient road system. The case study demonstrates, moreover, how a not conventional archaeological approach may also highlight the prominence of river connections for economic and social development.
