Gli stendardi d’Harcourt nel duomo di Oristano
No full textAll’interno del duomo di Oristano si conservano dei monumentali stendardi testimonianza di un episodio della guerra dei Trent’anni, operato nel 1637 da una flotta francese al comando del conte D’Harcourt. A seguito dell’intervento di restauro della Soprintendenza ai BAP-PSAE di Cagliari e Oristano negli anni 2002-03 (I lotto: Bruna Usai; II lotto: L’Ermesino), gli stendardi vengono presi in esame dal punto di vista storico-artistico istituendo opportuni confronti tecnici e stilistici, dall’altro mettendo a fuoco le figure dei protagonisti di quell’avvenimento storico di portata europea che coinvolse la Sardegna
Arturo Raffaldini restauratore e "alchimista" a Mantova
No full textIl catalogo della mostra dedicata ad Arturo Raffaldini (Mantova, Chiesa di Santa Maria della Vittoria, 23 settembre-24 novembre 2012) illustra il percorso artistico del pittore e restauratore mantovano, di cui ricorre il cinquantesimo anniversario della morte e propone opere, in gran parte inedite, di proprietà degli eredi o provenienti da collezioni private.
Nato a Mantova nel 1899, Raffaldini studia presso l'Accademia di Brera di Milano, manifestando un precoce talento soprattutto come ritrattista. A soli diciotto anni vince il premio Hayez, indetto dall’Accademia di Brera, della quale nel 1921 sarà nominato socio onorario.
All'attività pittorica si affianca ben presto quella di restauratore, che lo vede muovere i primi passi nel cantiere aperto a Mantova per il recupero di Palazzo Ducale, dove Raffaldini ricopre, fra il 1927 e il 1935, il ruolo di responsabile dei restauri e, in tale veste, segue i lavori sulle pareti non istoriate della Camera degli Sposi di Mantegna e della Galleria della Mostra. La sua attività prosegue anche durante la guerra con interventi ai limiti del rocambolesco, come l'episodio di salvataggio, nel 1944, dell'affresco di Piero della Francesca staccato dalle pareti del Tempio Malatestiano di Rimini, sotto il pericolo dei bombardamenti. Nel 1947, Raffaldini si trasferisce a Firenze e al restauro, divenuta la sua principale attività, egli deve la notorietà nell'ambiente artistico non solo nazionale. In tal senso, la mostra costituisce anche una preziosa occasione per studiarne, per la prima volta in modo sistematico, la figura e l’operato, attraverso i contributi di Daniela Sogliani, che illustra gli interventi di Raffaldini a Palazzo Ducale a Mantova, e della curatrice della mostra, Elena Stendardi, che ne ripercorre l'articolata attività nel resto d'Italia, seguendone le tracce da Trento a Bologna, da Ferrara a Napoli. Dopo una breve malattia, Raffaldini si spegne a Firenze, il 24 gennaio 1962. Nel 1965, viene organizzata una mostra retrospettiva a Mantova e poi, inevitabilmente, le sue esposizioni diventano molto rare

Thermal history of the Epiligurian Marzabotto wedge‐top basin records the tectonic development of the Northern Apennines (Italy)
No full textApatite fission track (AFT) and U-Th/He analyses (AHe) of detrital minerals from Eocene to Pliocene siliciclastic deposits in the Northern Apennines were here applied to constrain the tectono-thermal history of the wedge-top Epiligurian Marzabotto Basin (EMB). Detrital AFT age populations from Eocene to Miocene strata cluster between similar to 71 and similar to 58 Ma. AHe ages show a quite variable single grain age distribution ranging from similar to 104 to similar to 7 Ma indicating some degree of post-depositional thermal resetting. Thermal modelling of AFT and AHe data indicates that the EMB experienced a maximum temperature of similar to 90 degrees prior to Oligocene-to-Pliocene cooling. We interpret the Oligocene-Early Miocene cooling signal to represent rock uplift associated with growth of the Apennines orogenic wedge and the late Miocene-Quaternary cooling to track frontal accretion in the orogenic wedge concomitant with rollback-driven extension
Who am I really? The ephemerality of the self-schema following vmPFC damage
No full textWe studied the role of the ventromedial prefrontal cortex (vmPFC) in supporting the self-schema, by asking vmPFC patients, along with healthy and brain-damaged controls, to judge the degree to which they (or another person) were likely to engage in a series of activities, and how confident they were in their responses. Critically, participants provided their judgments on two separate occasions, a week apart. Our underlying assumption was that a strong self-schema would lead to confident and stable self-related judgments. We observed that control groups exhibited higher across-session consistency for self-related compared to other-related judgments, while this self-advantage was absent in vmPFC patients. In addition, regression analyses showed that in control groups the level of confidence associated with a specific (self- or other-related) judgment predicted the stability of that judgment across sessions. In contrast, vmPFC patients’ confidence and rating consistency were aligned only for other-related judgments. By contrast, self-related judgments changed across sessions regardless of the confidence level with which they were initially endorsed. These findings indicate that the vmPFC is crucial to maintaining the self-schema and supporting the reliable retrieval of self-related information
Multiscale structural analysis of an Epiligurian wedge-top basin: insights into the syn- to post-orogenic evolution of the Northern Apennines accretionary wedge (Italy)
No full textWedge-top basins represent useful tectonic elements for the characterisation of the evolution of their underlying accretionary wedge in space and time, as their final state of deformation sums up the bulk shortening and structural instability conditions of the wedge. Here, we present the geometric and kinematic patterns of deformation structures deforming the wedge-top Epiligurian basins of the Northern Apennines (Italy). Our main goals are to generate an evolutionary model to account for the syn- to post-orogenic evolution of the Epiligurian basins and to infer the building style of the Northern Apennines wedge during continental collision. Mesoscale structural analysis shows that common and widely distributed thrust and normal fault arrays deform the entire Epiligurian stratigraphic succession infilling the broadly E-vergent wedge-top basins. Thrusts are invariably cut by later NW-SE and NE-SW-striking normal and oblique fault systems characterised by fault planes that mutually intersect at all scales to form polygonal patterns. Remote sensing analysis of the tectonic structures affecting the Epiligurian formations confirms the variable orientation of both thrusts and normal faults within the different studied stratigraphic successions. As a whole, results suggest a polyphase tectonic evolution of the Epiligurian wedge-top basins during the widening of the Northern Apennines accretionary wedge towards the foreland by frontal accretion. The recognised main phases are: (i) syn-orogenic compression accommodating overall tectonic transport towards the eastern quadrants; (ii) post-orogenic extension genetically related to the extension of the inner zone of the Northern Apennines; (iii) more recent extension forming collapse-induced normal faults spatially arranged in polygonal patterns
