XRF dataset of Isis

Archaistic statue of Isis from the northeast corner of the portico of the Temple of Isis, in Pompeii (VIII - 7, 28). The goddess is depicted in an archaic style and likely dates to the Claudian period. Clear references to the Archaic Greek period can be seen, as the style of the representation echoes the posture of a kore. The hairstyle, held in place at the temples by an archaizing crown, is also a clear citation of that era. She wears a large necklace with geometric patterns and a dress of veils that clings to the body, revealing the breasts in their entirety. She holds her right hand raised, which probably once held a sistrum, while her left hand, resting along her side, supports an ankh, the quintessential symbol of the Goddess. A dedication found on the pillar connects the statue to Lucius Caecilius Faebus.

This analytical technique permits the determination of an element's composition in a material through the observation of characteristic secondary X-rays (or fluorescent) emission. This phenomenon occurs when a material is excited by primary X-rays. The technique is particularly valuable in the field of Cultural Heritage, where it can be employed for the analysis and characterization of a diverse range of materials, including paintings, manuscripts, monuments, metals, and others.
