Marble analysis, 4823
Fragment of a relief: Orpheus among the animals
Limestone
Limestone origin: local
Microfacies: the sample is altered but we recognize fragments of shells.
It is realistic to expect that this rock has been extracted in the country of the sculpture workshop where this artefact was carved. This variety of limestone is not very prestigious for exportation.
