The colors of the Fontana di Trevi: an analytical approach

During the last restoration of the Fontana di Trevi -Rome (2014–2015), it has been performed a diagnostic investigation to characterize the materials used to build and obtain the colors of the surfaces of some architectural elements of this fountain. According to the restoration teamwork needs, we focussed our efforts on the dome over the central statue of Oceanus, on the bas-relieves on the sides of the dome, and on the cliff where the water flows. Several samples were collected from these elements and therefore, they were subjected to an analytical approach including infrared spectroscopy, optical and scanning electron microscopy. The achieved results indicated the use of red earth pigments on the dome. The same pigment has been revealed on the bas-relieves, although their colors have an additional contribution due to degraded layers. Samples taken from the cliff showed a complex stratigraphy, although a white scialbo has been identified as original layer, testifying the intentions of the authors in term of color rendering. This information was essential for the restores in order to choose the proper intervention procedure for each investigated surface. The research testified the importance of an integrated diagnostic analysis to preserve the original colours of monuments and building.     

Innovation policy at the local and national levels: The case of Emilia‐Romagna

The article describes the main Italian policy instruments for innovation and how these have been used by companies located in the Region of Emilia‐Romagna. It also describes the role played by structures set up at the local level in the enactment of innovation policies in Emilia‐Romagna. In the first part, the article analyzes the current organization and legislation of Italian innovation policy; and in the second part, it examines the reasons which have led to the recognition of the importance of the local level of innovation policy, looking more closely at innovation initiatives in the Region of Emilia‐Romagna. In the third part, it draws the conclusions. In particular the article underlines that Italian local governments, even without legislative and financial autonomy, can play an important role in modernizing the industrial system through initiatives which do not require vast sums of money but which identify and meet specific local needs.     

Identification of a chrysocolla amulet in an Early Dynastic child mummy

Two pyriform formations were identified within a bundle of linen bandages wrapping a 15–18 months old Early Dynastic mummy. The upper one was taken out of the bandages and examined to ascertain its nature.     

Further Insight into Mesoamerican Paint Technology: Unveiling the Colour Palette of the Pre‐Columbian Codex Fejérváry‐Mayer by Means of Non‐invasive Analysis

Here, we report on the analytical findings and their cultural implications of a multidisciplinary study of the pre‐Columbian Codex Fejérváry‐Mayer. Today conserved at the World Museum in Liverpool, it is one of the finest Mesoamerican codices among the few extant. Thanks to the exploitation of non‐invasive analytical methodologies accessible through the MOLAB European mobile facility, the study allowed us to disclose the chemical composition of the painting materials used in the codex, which have never been analysed before. The results are discussed and compared with the outcomes of previous studies on other Mesoamerican codices.     

Immunological evidence of Plasmodium falciparum infection in an Egyptian child mummy from the Early Dynastic Period

A 15–18 months old child mummy, presently housed in Turin's Museum of Anthropology, was discovered in Gebelein (Upper Egypt) during excavations carried out by the Missione Archeologica Italiana, most likely in 1914.     

Archaeometric evidences of the 4th–2nd century BC amphorae productions in north eastern Sicily

This work focuses on the petro-archaeometric analysis of several transport amphorae dated back from 4th to 2nd century BC which were found in various archaeological excavations recently carried out in Messina and Milazzo (north eastern Sicily). These amphorae, generally known as Graeco-Italic, raise the problem of the identification of their production areas. Petrographic analyses proved the presence of two groups characterised by the presence of coarse metamorphic or volcanic inclusions and one group with finer metamorphic inclusions. Multivariate statistical analyses made it possible to detect the production area of the amphorae with metamorphic inclusion in north eastern Sicily, comparing them with locally produced bricks and clay sediments cropping out near the ancient cities. On the contrary, the studied amphorae rich in volcanic inclusions have petrographic and chemical features which can be attributed to production areas in the Campanian region.
