The application of Fourier Transform (FT) Raman spectroscopy to three coloured pigment samples and a white pigment from biodeteriorated sixteenth century Italian Renaissance frescoes located at the Palazzo Farnese, Caprarola, Italy, is reported. The samples provide a difficult example for Raman spectroscopic characterization owing to the complexity of the biodeteriorated encrustation, which includes incorporated substratal material and lichen metabolic by‐products. Some of the pigments used were identified and the potential of FT‐Raman spectroscopy as a means of aiding conservation of such artistic artefacts was demonstrated. © 1997 John Wiley & Sons, Ltd.
