Strontium and oxygen isotopes as indicators of Longobards mobility in Italy: an investigation at Povegliano Veronese.

The arrival of the Longobards in Northern Italy in 568 CE marked a period of renewed political stability in the Peninsula after the collapse of the Western Roman Empire. The trajectory of the spread of Longobards in Italy across the Alps and into the South is known from many literary sources. However, their mobility and residence patterns at a population level remain to be fully understood. Here we present a multi-isotopic analysis (87Sr/86Sr and 18O/16O) of 39 humans and 14 animals buried at the Longobard necropolis of Povegliano Veronese (VR, Italy; 6th-8th century CE), to address mode and tempo of the spread of this population in the Peninsula. The geographical location of Povegliano Veronese plays a key role: the site lies along the Via Postumia, which was one of the main ancient Roman roads of Northern Italy, representing an important route in post-classical Italy. The integration of isotopic data with the archaeological evidence allowed us to determine the presence of individuals from at least three different regions of origin, building a diachronic map of the dynamics of mobility of this group in northern Italy.

A possible case of mycosis in a post-classical burial from La Selvicciola (Italy).

An examination of an adult male buried from the post-classical necropolis of La Selvicciola (Viterbo, Latium, Italy; 4th-6th centuries AD) revealed a series of skeletal lesions. The lesions, both proliferative and lytic, ranging in size from small (around 0.01 mm) to extensive (up to 16.00 mm) pits, occurred at multiple sites. A holistic approach assessed lesion type, frequency and location in a differential diagnosis, which included myeloma, metastatic carcinoma, tuberculosis, leukemia, osteomyelitis, and mycoses. It was concluded that a mycosis, specifically Cryptococcosis, was the most likely cause of these lesions. Both macroscopic analyses and X-ray scans support our diagnosis. We also provide a methodological scheme as a model for examining unknown lesion patterns.
