Considering our previous relation with the the Soprintendenza Speciale Per I Beni Archaeologici Di Napoli E Pompei and the Pompeii’s Applied Research Laboratory, in 2015 an agreement was signed between the University of the Basque Country (UPV/EHU) and the Soprintendenza Speciale Per I Beni Archaeologici Di Napoli E Pompei. Thanks to that, in October 2015, APUV was able to perform a research expedition in the House of Gilded Cupids, one of the most important houses from Pompeii due to the majestic Fourth Style frescos, floor mosaics and the unique mirror preserved in the entire archaeological site. This was the first time that a research group was able to apply its in situ analytical strategy in a house open to the public, thus we were able to work inside the rooms of the house while visitors came into it. In this field campaign also our portable non-invasive instruments were moved to the house in order to characterize the original composition of the pigments and mortars used in the walls and wall paintings of the house and also to evaluate possible degradations or chemical transformations that could take place on these materials.
Additionally, several raw pigments recovered from the excavations and preserved in their original bowls were analyzed in situ with the same instruments in the Pompeii’s Applied Research Laboratory. This year, additional in situ analyses were also carried out in some frescoes extracted from the House of Marcus Lucretius after the first excavations of this house and nowadays preserved in the Naples National Archaeological Museum (MANN).
