The origin of "Rosso Antico"
Rosso antico was widely used throughout the Roman empire basically for opera sectilia, slabs, but also in rare cases for sculptures and sculptural decoration. According to the current opinion there are 3 different regions where "Rosso Antico" was mined:
- Different locations on the Peloponnesos
- Milas region in Asia Minor
- Iassos in Asia Minor
The databank includes 112 samples of Rosso Antico from the above mentioned regions. The isotope diagram satisfactorily separates the compositional fields of the 3 source regions. Multivariate discrimination using additionally chemical or fluid inclusion data is not improving the result.
Thus the Rosso antico is one of the rare cases where isotope analysis alone is sufficient for a sound discrimination of different source regions.
