Interdisciplinary Analysis of Roman Floor Types in the Villa of Diomedes in the Archaeological Park of Pompeii

Abstract

The present work presents and discusses an analysis of the floor types of the Villa of Diomedes (Pompeii archaeological park in the Campania region, Italy) from an architectural, archaeological, and structural point of view. In particular, the geometrical-structural parameters of different floor types and the rules used by ancient builders to design them are investigated by means of interdisciplinary research. The links between structural assumptions, archival sources, geometric survey, in situ visual inspections, and archaeological information make it possible to define the geometrical-structural parameters of eleven barrel vaults, three wooden floors, and three sloped wooden roofs (buried and collapsed during the Vesuvius eruption). A specific study of the barrel vaults is presented to investigate the relationships between the structural parameters of the main vaults. Furthermore, a comparison between the vaults’ dimensions obtained from surveys and those produced by formulations in the literature between the 15th and 20th centuries concerning masonry vault designs is presented and discussed. These analyses, carried out within the framework of the Villa of Diomedes interdisciplinary project, were very useful for interpreting the fabrication of the villa and making a 3D reconstruction model of how the villa probably looked in the fateful year of 79 A.D.
