Early Use of Lime Mortar at the Early Iron Age Piscina Torta Salt Production Site (Tiber Delta, Ostia, Italy)

This study presents new evidence for the early use of lime mortar during the Early Iron Age at the Piscina Torta site (Ostia, Italy), situated on the earliest Holocene beach ridges in the southern Tiber delta. The site, which was earlier described as a briquetage site, dates from between the late 8th and 6th century BCE and consists of a large complex of dumps, holding kilns and working floors. Lime mortar-like materials were abundantly present in these dumps and used in the construction of some kilns and working floors.
