Indagine sul fenomeno della standardizzazione nelle produzioni ceramiche provinciali in epoca tardo romana. La forma Hayes 85

The aim of this paper is to determine the degree of standardization within certain Late Roman pottery productions. This research tried to outline a methodology to determine the standardisation degree of these samples and to unravel the measurement systems used in the production process. The morphometric characterization of each fragment allowed us to create different groups with a cluster analysis. The principal component analysis providedinformation that led us to a deeper understanding of the obtained groups. The coefficient of variation allowed us to determine the standardisation degree of the productions. Once all these data are known, we can approach to the possible measurement units that ruled the analysed production systems. We selected a form well represented in the ceramic contexts identified in the excavations of the Late Antique port-canal of Classe, the Hayes 85 small bowl. This vessel was considered a rare form in Hayes’ monumental book. New discoveries of the last ten years revealed how much we still have to understand about the characteristics of Late Roman productions, trade and distribution. With this in mind, we used a statistical method to analyse the main changes in the profile of this type and its variants

Late Roman pottery standardization: Hayes 85 as a case study

This paper aims to determine the degree of standardization within certain Late Roman pottery productions. We selected a form well represented in the ceramic contexts identified in the excavations of the Late Antique port-canal of Classe, the Hayes 85 small bowl. The presence of many fragments and whole pieces of these forms at the port of Classe provided us with sufficient cases for statistical analyses and conclusive data. This vessel was considered a rare form in Hayes’ monumental book. Discoveries of the last ten years show us how much we still have to understand the characteristics of Late Roman production, trade, and distribution. With this in mind, we used a new statistical method to analyze the main changes in the profile of this type and its variants
