Abstract: The identification of an artist’s palette through the application of non-invasive techniques is a challenging goal due to the
huge variety of artistic materials that constitutes a painting. An effective approach is to combine several techniques providing complementary
information in order to minimise the risk of misinterpreting the data. In this paper, we propose a multi-analytical method
comprising three non-invasive mapping techniques, namely Reflectance Imaging Spectroscopy (RIS), Macro-X-Ray Fluorescence
(MA-XRF) and Fluorescence Lifetime Imaging (FLI), for the study of a fourteenth-century painting by Pietro Lorenzetti from
the Uffizi Gallery collection. For the low-cost and time-saving interpretation and integration of the data provided by the different
techniques, a purposely developed software for multivariate statistical analysis was used. FLI data were acquired with a prototype
applied for the first time on a work of art, and the data were processed with a method based on phasor analysis. The information
obtained was discussed within a multidisciplinary team of experts on painting materials and data processing belonging to both the
scientific and the conservation community.
