What jewelry did people wear in the Middle Byzantine period (10th-12th C. CE) in the Peloponnese? A technological and analytical case study

The present paper presents the preliminary results of the archaeometric analysis of a Middle Byzantine jewelry assemblage made of non-precious metals from the ancient site of Pallantion, near Tripoli (Peloponnese, Greece). The assemblage under examination consists of 26 artifacts, including earrings, finger rings and buckles. Macroscopic observations and optical microscopy were used to examine the manufacturing technology of the artifacts, with a particular focus on the manufacturing technology of wires. The proposed methodology combined a Handheld X-ray Fluorescence Spectrometer (HH-XRF) and a Micro X-ray Fluorescence Spectrometer (μ-XRF) to group the alloys used in the manufacture of the jewelry, despite the presence of corrosion. This methodology indicated that the majority of the artifacts was made of bronze, leaded or not, and gunmetal. Moreover, a quantification criterion was used to determine the state of preservation of the surface of the jewelry. Overall, the present study highlights the manufacturing technology of jewelry of the Middle Byzantine period and the tendency to imitate silver jewelry with lower-cost materials.
