In the shadow of the church: the building of mosques in early medieval Syria
No full textIn his book In the Shadow of the Church: The Building of Mosques in Early Medieval Syria Mattia Guidetti examines the establishment of Muslim religious architecture within the Christian context in which it first appeared in the Syrian region, contributing to the debate on the transformation of late antique society to a Muslim one. He scrutinizes the slow process of conversion to Islam of the most important town centers by looking at religious places of both communities between the seventh and the eleventh century. The author assesses the relevancy of churches by analyzing the location of mosques and by researching phenomena of transfer of marble material from churches to mosques
Characterization of Soluble Salts on the Frescoes by Saturnino Gatti in the Church of San Panfilo in Villagrande di Tornimparte (L’Aquila)
No full textSalt crystallization is one of the most dangerous forms of degradation affecting frescoes.
This phenomenon can lead to cracking, flaking and detachment of the pictorial layer, ultimately ruining the work of art. However, the characterization of soluble salts via chemical analysis can be employed to determine the conditions of the artifact and establish the proper restoration and/or conservation strategies to be adopted. In this archaeometric study, a first-ever characterization of the soluble salts and related degradation phenomena on the frescoes by Saturnino Gatti in the church of San Panfilo in Villagrande di Tornimparte (L’Aquila) was carried out. Sampling was performed in areas with evident detachments, exfoliations and saline crystallization (efflorescences). Eleven samples of powder and fragments were taken from different panels of the fresco: nine were taken from Panels A, C, D and E and two from the top part of the vault. Chemical characterizations were performed using two analytical techniques: ion chromatography (IC) and attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR). Ion chromatography was used for the quantification of the main ions and to evaluate the presence of soluble salts, whereas infrared spectroscopy was used to characterize the mineralogical phases. The results show efflorescence consisting of newly formed gypsum and carbonate in samples taken closer to the ground. Furthermore, a good correlation between sodium and chloride ions was observed, indicating the presence of an efflorescence composed of newly formed sodium chloride. Capillary rise and infiltration were highlighted as the main sources of soluble salts. This information will be crucial in guiding future restoration or conservation operations

We have previously examined the antiviral activity of resveratrol on the replication of Epstein Barr Virus (EBV), the etiologic agent of infectious mononucleosis and associated with several types of malignancies of epithelial and lymphoid origin.
In a cellular context that allows in vitro EBV activation and lytic cycle progression through mechanisms closely resembling those that in vivo initiate and enable productive infection, we found that RV inhibited EBV lytic genes expression and the production of viral particles in a dose-dependent manner
Does Independence Affect Regulatory Performance? The case of national competition authorities in the European Union
No full textDespite having always been assumed to be true, a relationship between the independence of regulatory agencies and their performance has never been formally tested. This paper aims at verifying whether formal regulatory independence affects the performance of national competition authorities in the EU member states. The author presents and discusses a statistical analysis which shows that greater formal independence leads competition authorities to investigate more cases and to issue more decisions
Caterina Colombini (1304 ca.-1387) o della cugina sedotta. Una ‘ricostruzione’ della figura di Caterina attraverso i testi letterari, in Le vestigia dei gesuati. L’eredità culturale del Colombini e dei suoi seguaci, a cura di I. Gagliardi, Firenze, Firenze University Press, 2020, pp. 57-71 ISBN 978-88-5518-227-0
No full textIn this essay the author demonstrates that it is possible to reconstruct the figure of Caterina Colombini (1340?-1387) – Giovanni Colombini's cousin – through a group of texts: the hagiography of Caterina, the letters sent to her by Giovanni Colombini and, finally, Giovanni's biography written by Feo Belcari. The author divides his text into four parts: the first part analyzes the content of Caterina's hagiography; the second examines the linguistic form of the hagiographic text; in the third, the author analyzes the latent meaning of the window, a symbolic place where Giovanni and Caterina converse on divine topics; in the last part, to conclude, the teachings that Giovanni gives to Catherine and her spiritual daughters – the Gesuate – are analyzed

The album of Mattia De Rossi’s drawings. Projects for the Galleria Colonna ai Santi Apostoli
No full textThe study proposed here on Mattia De Rossi, a pupil of Gian Lorenzo Bernini and his most trusted collaborator, is part of an investigation that the author is doing on the figure of the architect, making use of an obvious investigative tool: his drawings.
In particular, the exceptional discovery of a bound volume of about 200 drawings of Mattia is a resource of great effectiveness for the study of his professional figure. Among the sheets of the collection, those relating to the construction site of the Galleria Colonna in the eponymous palace in Piazza SS. Apostoli in Rome, are presented.
These drawings explain the important contribution of Mattia and the creative process that led him to the definitive version of the central hall of the gallery. The drawings are also the only graphic documents related to the project of the Galleria Colonna, now only partially known through hypothetical reconstructions.
The case of the Palazzo Colonna is similar to other projects included in the volume, which enlighten us on De Rossi's career, and which explain his position in several important Roman buildings of the second half of seventeenth centur
A Choreographic Dialogue with Caribbean Poetry: The Sacredness of the Feminine in Walcott's Omeros (1990)
No full textThe aim of this paper is to show how the poetry and art of Caribbean writer Derek Walcott (1930-2017) tends to manifest and substantiate the desirable cultural transformation promoted by the work of the American anthropologist and scholar Riane Eisler. The recognition and the exaltation of symbols connected to the feminine world stand at the core of Walcott’s masterpiece Omeros. In a creative mutual dialogue between different genres and identities, the Caribbean author materialises Eisler’s attempts to forge a type of society based on a new partnership ethic. In a second perspective, this paper analyses how Walcott’s work opens the path to possible creative interdisciplinary approaches in the world of the arts. In my own contribution, as a professional dancer and choreographer, I have tried to “give voice” through movements to some episodes relating to the feminine included in Omeros
Multitechnique diagnostic analysis and 3D surveying prior to the restoration of St. Michael defeating Evil painting by Mattia Preti
No full textIn this study, a multimethodological analysis involving optical and physical/chemical diagnostic techniques and 3D photogrammetric survey was successfully applied, for the first time, on the large oil on canvas St. Michael defeating Evil painting by Mattia Preti, located inside the Church of the Immaculate Conception of Sarria (Floriana) in Malta. Pigmenting agents, binder media, and raw materials were first characterized, both at elemental and molecular scales, through X-ray fluorescence spectroscopy (XRF), optical stereo microscopy (SM), scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDX), Fourier transform infrared spectroscopy (FT-IR), and gas chromatography coupled with mass spectrometry (GC-MS). The main goal was to properly identify the execution technique of this famous painter, the artist’s palette, and possible nondocumented interventions. The 3D photogrammetric survey, on the other side, allowed us to noninvasively evaluate the extension of the areas that experienced restorations, and to properly map the domains of the different canvasses observed. The joints between canvasses suggested that the painting was folded and rolled up. In addition, the employment of a thermal camera gave evidence of the different consolidating material injection points used during the restoration to strengthen the painting. The obtained results offer useful information for the development of optimized restoration and conservation strategies to be applied and provide, at the same time, answers to open questions related to provenance and dating of the investigated artwork
A Female Mystic and Educator in the Medici grand Duchy: Hagiography of the Venerable Leonora Ramirez de Montalvo (1602-1659) from medieval to modern topoi, in «Rivista di Storia e Letteratura religiosa», 2019/2020-a. 55, pp. 229-265 ISSN 0035-6573
