A Stratified Route Network in a Stratified Landscape. The Region of Enna (Central Sicily) from the Bronze Age to the 19 th c. AD.

This paper focuses on the region of Enna in central Sicily. Its peculiar environmental setting is a key feature, with a central mountain surrounded by gentle, fertile lowlands. Our key question is to understand the regional route network in its historical process of “transformission”, a concept proposed by French archaeogeographers (see Chouquer, Watteaux 2013). It considers traces on the landscape at different scales, as ever-changing features influenced by both natural and human inputs. We chose a sample area of 566 sq-km in the very centre of the island and we evaluated geographical constraints on mobility. This raises new questions about the relationship between routes, settlements, and the environment
