Technical and workmanship details reveal that the stuccoes were part of a magnificent decorative apparatus, likely incorporating mural paintings, marble cladding and cornices. No stucco fragment matches with fragments of different technique. Though, matching pieces have been found among stucco finds.
A group of fragments with curve surface shows a relief decoration with dolphins against a blue background. A second group includes finely modeled acanthus leaves, partly in relief, partly engraved on the surface. A third group displays human figures. They are rendered in relief with an inner layer of lime based plaster, finished with an outer layer of lime and marble powder, polished in certain areas.
After cleaning, some of these pieces were selected for display in the museum. The selected fragments were recomposed, their lacunae were stuccoed and their surface was treated with a protective coating.
