Pittura antica e restauro virtuale
2020
This contribution presents the preliminary work, carried out over the past few months, concerning the reconstructive study of the paintings and mosaics of the Centennial House ", Insula IX-8, in Pompeii. In particular, the work focused on the decorated surfaces of 11 rooms located along the western part of the house, between the large central peristyle and the centenary alley. The different state of conservation of the paintings and mosaics made it necessary to use two different methods of digital intervention: the "virtual restoration" and the "virtual reconstruction". Both aim to reconstruct the initial condition of the appearance of the paintings at the time of their creation and use the…
The mosaic of the Frigidarium of “Villa Bonanno” in Palermo: mineralogical and petrographic analyses for in situ conservation and restoration interve…
2017
The topic of this study was the mineralogical and petrographic characterization of bedding mortars (made of different layers) and tesserae of Roman age (3rd Century A.D.), taken from the mosaic of the Frigidarium of “Villa Bonanno”, brought to light by archaeological excavations conducted in the historical centre of Palermo. The collected samples have been analysed by thin-section optical microscopy (PLM), and scanning electron microscopy coupled with energy dispersive spectrometry (SEM-EDS). The study was aimed to define the “recipe” (composition of temper and binder, temper size distribution, temper/binder ratio), in order to assess the provenance of raw materials (supply site/area) and t…
3D ERT for the study of an ancient wall covered by precious mosaics
2009
The DC electrical tomography (ERT) is still a method scarcely diffused for the study of masonry of recent and ancient buildings, in spite of the very high resolution power of this methodology. The major limitation on ERT applicability on precious surfaces (like masonries or floors with fresco or mosaic covering) depends on the method of current injection: usually it is necessary to drive electrodes (small nails) into small perforations on the surfaces, to obtain sufficiently high current values (to produce good signal to noise ratio). An interesting application of the MYG array (that reduces significantly, compared to other classical arrays, the number of electrodes utilized for current inj…
Un dialogue entre l'humain et le divin. Les paroles monumentales à Saint-Clément (1118) et à Sainte-Marie-du-Transtévère (v. 1143) à Rome
2019
The textual formulas inscribed in the basilical decors of San Clemente and Santa Maria in Trastevere at Rome, encourage to think about the presence, the power and the significance of the voice in ecclesial spaces. Unrolled on phylacteries or inscribed in gold letters on apsidal conch, the words from sacred texts, but also the legends and the dedications aim to establish the auctoritas of the visual discourse. Perpetuated voices of the prophets, apostles, of Christ and the Church take part in the monumentality of the decor. These inscribed voices animate and update the decor at the rythme of liturgies. We propose to consider these inscriptions as crystallization of historic contexts. The Chu…

The topic of this study was the mineralogical and petrographic characterization of bedding mortars (made of different layers) and tesserae of Roman age (3rd century A.D.), taken from the mosaic of the Frigidarium of “Villa Bonanno”, brought to light by archaeological excavations conducted in the historical centre of Palermo. The collected samples have been analysed by thin-section optical microscopy (PLM), and scanning electron microscopy coupled with energy dispersive spectrometry (SEM-EDS). The study was aimed to define the “recipe” (composition of aggregate and binder, aggregate size distribution, aggregate/binder ratio), in order to assess the provenance of raw m…
New Gynandromorph Records for Chirocephalus diaphanus (Branchiopoda, Anostraca, Chirocephalidae)
2021
We report and describe new Chirocephalus diaphanus Prévost, 1803 gynandromorphs from Tunisia and review the literature of anostracan gynandromorphy and other, possibly associated, somatic aberrations, with comments on their evolutionary significance. Our material has three specimens that are specifically deformed on the left side of the head.
