Scientific investigation of The Conversion of St Paul painting (Mdina, Malta)

The paper presents the results of two different approaches applied to the newly-restored painting The Conversion of St Paul, the main altarpiece in the Cathedral of Mdina in Malta. This large, dramatic painting is work of the Baroque artist Mattia Preti, il Cavaliere Calabrese. As is normal with a professionally executed restoration, several scientific methods have been used before, during and at completion, in the framework of a global analytical strategy. In particular, we focus on the results of the digital photogrammetric survey which uses image-based approaches for 2D/3D models reconstruction enormously. The model was used to quantify and measure important features on the painting as well extensions of areas restored. In addition, portable Raman spectroscopy was used to identify, in non-destructive way, the nature of the painting materials with the final goal of reconstructing the color palette of the artist.peer-reviewe

The watch towers in Malta : a patrimony to preserve for the future

In this contribution we will focus on some results achieved within the international bilateral project “Non-invasive investigations to enhance the knowledge and the enjoyment of cultural heritage” (funded by the Italian National Research Council and by the University of Malta). In particular, we will focus on some GPR and geoelectrical investigations performed on the so called Red Tower and on the so called White Tower, both on the western side of the island of Malta.peer-reviewe
