“…Scarce information can be obtained from the nail composition (mostly Fe, with a sedimentary cap), while the characterization of the orange bead is troublesome. μ-XRF showed quite an inhomogeneous chemistry, hardly consistent with that of an ancient glass—especially for what concerns the nature of the chromophores/opacifiers (e.g., the absence of Fe and Cu; see Table 3b in the Appendix B; Capra et al 2005; Charalambous et al 2010). Its contextualization in the studied burial context remains, therefore, dubious.…”

In 1989 an ancient burial consisting of a skeleton and a few objects was discovered at the Monte dei Cappuccini Monastery, in Torino (Italy). Anthropological analysis of the skeleton revealed that it belonged to a young man, and the archaeometric characterization of the objects suggested that most of them are compatible with the Medieval period. As a proper archeological survey was not conducted at the time of the finding, due to the religious nature of the site, a high-precision radiocarbon (14C) dating has been performed. The samples were processed with three different methods: besides the ultrafiltration (UF) treatment, we applied the “collagen” (COL) and the Longin-base (LB) methods. While UF and COL treatments provided compatible results, LB method returned ages older with respect the UF one, with significant disagreements in some cases and this evidence is supported by several measurements on the same individual. Thanks to the reduction of the uncertainty with the high number of measured samples and the availability of historical evidence, the possible age of the burial has been limited to the time interval 1464–1515 cal AD.
