XRD analysis of patinas on the monument dedicated to Saint Oronzo, Lecce

Abstract

The monument dedicated to Saint Oronzo is placed in the homonymous square in the city centre of Lecce (Southern Italy). This monument consists of an internal wooden structure that is completely covered with copper sheets, lying on a concrete base about 1.5 meters high, which is placed on a Roman column about 29 meters high. The restoration of this manufact started in June 2018 and, first of all, non-destructive analyses are planned as proposed in the time-schedule. In this paper, we show the results of X-ray diffraction (XRD) analysis of the patinas both of the statue and of the column in order to evaluate their composition.
