Investigation of the pigment use in the Tomb of the Reliefs and other tombs in the Etruscan Banditaccia Necropolis

The pigment use in the Tomb of the Reliefs (4th century BC) and four other tombs (7th-4th century BC) in the Etruscan Banditaccia Necropolis near Cerveteri, Italy, has been investigated. We made use of XRF and Raman spot analysis, XRF imaging, IR luminescence and photography supported by Dstretch contrast enhancement. We identified the use of haematite, goethite, calcite, carbon black, manganese oxide, Tyrian purple and Egyptian blue, with the last three only found under the central burial place of the Tomb of the Reliefs. The tuff in which these tombs were cut proved to be a significant challenge for XRF analysis as the signals of Ca, Mn and Fe vary strongly due to the heterogeneity of the stone, so that it is difficult to distinguish between signals from the tuff and the pigments. Finally, we show that lightweight instruments transported in check-in luggage may not answer all questions on pigment use, but do provide additional insights
