The Lovatelli Venus, named after its discoverer, was unearthed in 1873 in a niche in the peristyle of the House of Diomedes I, 12-17 in Pompeii. The dating of the sculpture goes back to the Julian era. Her hair is gathered into two braids that part from the centre of her forehead to gather into a bun. She wears both a light chiton and a heavy himation that wraps around her hips and coils around her left arm. She holds an apple in her left hand, a clear reference to the Judgment of Paris. Sinuous and nude down to her legs, she displays visible traces of polychromy and holes in her earlobes, which, following the fashion of the time, likely held golden earrings, accompanied by bracelets on her wrists. While the chiton was certainly white, the himation shows large areas of yellow alternating with the green of the peplos. On the left side, the goddess leans against an anthropomorphic-style column decorated on the front with an archaizing idol.

Research activity
- Research Activity Type
- Object Examination/Material characterisation
- Technique
- External Reflectance FTIR spectroscopy
- Technique Category
- Point analysis
- Method Description
-
Portable FT-IR with external reflectance module, allowing measurements without sampling. The acquired spectra provide information for the characterization and identification of organic and some inorganic materials (e.g. binders, coatings, etc.) based on the excitation of specific vibrational modes of functional groups in the infrared region
- Tool / Equipment (or Software) Description
-
Alpha Bruker spectrometer (Bruker) equipped with the external module

- ROI or target area or spot size
- 6mm, 5 mm or 3 mm
- Examination Methodology
-
acquisition of an FT Infrared spectrum by selecting the area under investigation and the number of scans for each point.
- Equipment setup - Experimental
-
Working parameters: sample scans 128, background scans 128, resolution 4 cm-1
- Output interpretation
-
spectrum with bands corresponding to specific vibrational modes of functional groups of organic and inorganic materials such as aliphatic, aromatics and carbonyl groups.
