Abstract

The \"Dancing Satyr\", a bronze statue measuring more than 2 metres in height and weighting 108 kg, represents one of the most important recent archaeological finds in Italy. The statue was discovered on the floor of the Sicilian channel (the portion of the Mediterranean sea between Sicily and Tunisia), not far from the south-western Sicilian coast, under 500 metres of seawater in 1998. The bronze statue depicts a nude satyr captured in a frenzied whirling movement during a dance in honour of Dionysus, the God of wine. Though some scholars dated it to the IV century B.C. as an original Praxiteles work or a copy thereof, it could be also dated either back to the Hellenistic period (III or II century B.C.) or possibly to the Roman Empire age (early II century A.D.). The nature and structure of the corrosion products grown on the Dancing Satyr surface and the metallurgical features of the statue were investigated taking into account the nature of the marine environment of provenance. A detailed micro-chemical and micro-structural characterization was performed by means of the combined use of scanning electron microscopy (SEM), energy-dispersive spectrometry (EDS), X-ray diffraction (XRD) and optical microscopy(OM). Results provided good insight into the different corrosion layers and a tentative correlation of the patina nature and the chemical composition of the statue and the marine context is proposed.
