Il Progetto Domus Tiberiana (Roma): gli approvvigionamenti di laterizi per i cantieri adrianei lungo la Nova Via

The Domus Tiberiana Project started in 2013 and is coordinated by the Soprintendenza Speciale per il Colosseo e l’area archeologica centrale di Roma. It aims at a new and comprehensive study of the first imperial palace on the Palatine. Several aspects are considered, integrating the results of preceding research into new analyses archived inside the GIS SITAR of the Soprintendenza: the study of wall stratigraphy, building techniques, decoration systems, archaeological finds, and architectural restorations. This paper shows the first results of the survey of building techniques and materials used in the Hadrianic block along the western section of the Nova Via , built at the same time as the enlargement of the north-western corner of the Domus Tiberiana . In particular, metrological analysis of bricks has proved how the different supplies of bipedales, sesquipedales, bessales, broken roof tiles and reused bricks were arranged inside the building. In fact it seems that the distribution of building techniques in the different portions of the construction was planned according to an economic and structural rationale.
