Abstract

Samples from the opus sectile panel excavated from the
Episcopal Residence building at the archaeological site
of Stobi were examined using X-ray powder diffraction, SEM-EDS, and Raman spectroscopy. The analyzed
samples, exhibiting plentiful color and surface variations, comprise the reconstructed sectile panel as well as
represent the in situ ground remains. The complementary techniques revealed dominant amorphous phase in
five samples, whereas the remaining seven specimens
confirmed the presence of magnesite, quartz, dolomite,
ankerite, cuprite, wüstite, and hematite. The work represents the first systematic attempt to determine the mineral
phases in the restored opus sectile panel, assembled by
decorative minerals forming a geometric net of polychrome crosses. Furthermore, the mineral characterization
has revealed an origin of mineral species not typical for
Macedonian terrain (ankerite, wüstite, cuprite, transparent
quartz) that lead to the conclusion that the samples were
likely imported from other early-Christian communities.
