In this work, we studied the canvas "The meeting of the pilgrims with the Pope" by Vittore Carpaccio fusing in a single data structure the pointwise XRF analysis with the Vis-IR multispectral data acquired on the painting. We proposed a workflow for analyzing and interpreting the data using Principal Component Analysis. The effectiveness of this approach is evaluated against the analysis of the data analyzed as separated contributions. The proposed procedure is demonstrated on the red pigments, which are predominant in this painting and in Carpaccio's production in general, highlighting information regarding the original artist's technique and regarding restored areas.

Abstract

In this work, we studied the canvas "The meeting of the pilgrims with the Pope" by Vittore Carpaccio fusing in a single data structure the pointwise XRF analysis with the Vis-IR multispectral data acquired on the painting. We proposed a workflow for analyzing and interpreting the data using Principal Component Analysis. The effectiveness of this approach is evaluated against the analysis of the data analyzed as separated contributions. The proposed procedure is demonstrated on the red pigments, which are predominant in this painting and in Carpaccio's production in general, highlighting information regarding the original artist's technique and regarding restored areas.
