The Roman Houses of the Caelian Hill (Rome, Italy): Multitemporal Evaluation of Biodeterioration Patterns
No full textLike other hypogeal environments, the Roman Houses of the Caelian Hill are prone to unwanted biological growth. Wide conservative interventions have been carried out at the beginning of this millenium to reduce biodeterioration and physical-chemical damages. Retracing the last monitoring work, we assessed the site's current state of conservation and biodeterioration intending to check the previous treatments' effectiveness and deepen the common knowledge of the subterranean biota and their possible biodeteriogenic effects. Starting from the past test areas and the previous identifications of the occurring biodeteriogens, we further isolated and identified the main eubacterial, fungal, and phototrophic settlers, focusing on some detrimental traits for wall paintings (i.e., acid production and carbonate precipitation). The achieved results proved the success of the performed interventions in reducing the wall's water content. Otherwise, the new conditions raise, in the long term, new concerns about lampenflora, carbonate precipitations, and salt efflorescence. Here, the Caelian Houses' new status is documented. The possible favouring conditions for the different groups of biodeteriogens, along with the taxonomical novelties, additional risks tied to the anthropization of the resident culturable microbial community, and the possible relation between the black fungus Cyphellophora olivacea and roots, are reported and discussed
Il senatore Cornelio Pusione e la sua domus. Novità dagli scavi della metro C a Roma
No full textA new fistula aquaria, found, during the works for the construction of the metro line C, in the garden of a private house to be dated around the middle of the I century AD, in Rome, on the Caelius hill, re-opens the problem of the location of the domus belonging to L. Cornelius Pusio. The house of this senator was traditionally located in the area of via IV Novembre, where a bronze dedication was found, together with a portrait. But the suspect that these findings were not in their original location is now confirmed by the new discovery
Un tratto di acquedotto repubblicano rinvenuto negli scavi Metro C di Piazza Celimontana, Roma
No full textNel mese di dicembre 2016 si sono concluse le indagini archeologiche svolte nei giardini di piazza Celimontana sul Celio in occasione dei lavori della tratta T3 della linea C della Metropolitana di Roma, che collega S. Giovanni in Laterano al Colosseo. Lo scavo, preliminare alle opere civili, è stato eseguito all’interno di un pozzo circolare di aerazione di circa 32 metri di diametro, esteso su una superficie di oltre 800 metri quadri, ubicato nell’angolo nord-orientale della piazza. Nell'ambito delle ricerche è stato messo in luce un tratto di acquedotto sotterraneo medio repubblicano, interamente realizzato in opera quadrata che, con andamento est-ovest, attraversa l’asse centrale del Pozzo e prosegue oltre le paratie di cemento che delimitano l’area d’indagin
Assessing readability of the text in ancient paper fragments by a photometric statistical analysis
No full textAncient documents are important historical sources that are often found in a fragmented
condition due to their conservation status. In this study, we examined fragments of paper found in
1996 during excavation of the Santi Quattro Coronati complex, in Rome. The archaeological site
where the fragments were found is situated on the first floor of the tower within the complex. This
location was used as a disposal pit approximately between the 15th and 16th centuries. The fragments
exhibit text discoloration, hindering automatic recognition and human readability. To reveal the faded
text, the fragments have been digitalized, converted into a perceptually uniform color space and
the contrast has been enhanced. The photometric characteristics of the input and enhanced images
have been statistically characterized, and the contrast enhancement assessed by a state-of-the-art
metric. The statistical analysis of the text colour coordinates was carried out to develop supervised
and unsupervised image segmentation, isolating the text.
The results of the method show that it effectively identifies text regions within images, improving
readability, even for faded text. It can be integrated into deep learning-based character recognition
systems, facilitating the automatic analysis of historical handwritten documents
Domus e horrea lungo il vicus Patricius

Tra archeologia e archeometria. Analisi preliminare degli indicatori di attività tessile e conciaria dagli scavi della Metropolitana C per la stazione Amba Aradam (Roma)
No full textThe paper investigates several archaeological finds connected to the textile and leather manufacturing processes. The instrumenta were recovered during the excavation of the Amba Aradam station of the Metro C line in Rome. All tools found are made of organic material. They are preserved in relatively good conditions, thanks to the permanently wet or humid and anoxic context of deposition. The artifacts (e.g. brush, combs, needles, blade shears) have been recovered in a secondary position, within pits dated just before of the establishment of the barracks, during the Trajan age. For the first time, this study gives an overview on the activities carried out on the site before the establishment of the barracks and the implements involved in the production processes. Furthermore, microscopic investigations were carried out in order to characterize the materials used for the manufacture of the tools
