“…In the 3rd century bc , the Romans started to extend their control to northern Etruria (Harris, 1971); in the territory of Populonia, the activity of metal-working reached its zenith (Dallai, 2000), after which, during the Civil Wars, it came to a definitive halt in the 1st century bc (Cambi and Acconcia, 2011). With the decline of Populonia, the network of settlements was re-organised and, between the 1st century bc and 1st century ad , archaeological evidence shows the maximum development of rural settlements in the valleys from Cecina to the River Ombrone (Cambi and Botarelli, 2004; Citter, 1996; Dallai, 2003b; Vaccaro, 2008). In the following century, however, the re-organisation of the Roman economy resulted in a new distribution of industrial activity which led to a sharp decrease in settlement population size (Citter, 1996; Dallai, 2003b; Vaccaro, 2008).…”
