Syros Island is worldwide known for its preservation of HP-LT parageneses in the Cycladic Blueschist Unit (CBU) providing one of the best case-studies to understand the tectonometamorphic evolution ...of a subduction channel. Conflicting structural interpretations have been proposed to explain the geological architecture of Syros, in part reflecting a lack of consensus about the tectonic structure of the CBU. In this study, the geological and tectonometamorphic maps of Syros have been entirely redrawn in order to decipher the structure of a fossilized subduction channel. Based on structural and petrological observations, the CBU has been subdivided into three subunits separated by major ductile shear zones. New observations of the Vari Unit confirm that it rests on top of the CBU through a detachment or exhumation fault. While retrograde top-to-the E/NE shearing overprinting prograde deformation is widespread across the island, the prograde deformation has been only locally preserved within the less retrograded units. We show that after the prograde top-to-the S/SW shearing deformation, the CBU was exhumed by an overall top-to-the E/NE shearing from the depth of the eclogite-facies all the way to the depth of the greenschist-facies and finally, to the brittle crust. The exhumation process encompassed the syn-orogenic stage (contemporaneous of subduction, within the subduction channel — Eocene) to the post-orogenic stage (contemporaneous with the formation of the Aegean Sea — Oligocene to Miocene). From syn-orogenic to post-orogenic exhumation, deformation progressively localized toward the base of the CBU, along large-scale ductile shear zones, allowing the preservation of earlier HP-LT structures and HP-LT metamorphic parageneses. Finally, this study brings new insights on the tectonometamorphic evolution of a subduction channel showing how strain localizes during the history of an accretionary complex, both during the prograde and retrograde history.

L’intervento discute l’originale interpretazione avanzata da Giorgio Agamben a proposito dell’opera dello scrittore italiano Antonio Delfini. In particolare il saggio analizza la centralità della ...riflessione poetica di Delfini nel sistema estetico agambeniano: l’intransigenza antimoderna di Delfini, infatti, è ricollegata da Agamben ad una riflessione generale sulla natura della parola poetica e relativamente alle mutazioni storiche del complesso rapporto tra opera e biografia nella cultura letteraria occidentale. In tal senso, il saggio riflette sul parallelo individuato da Agamben tra il significato profondo del racconto Il ricordo della Basca e l’idea di una “pura lingua” pre-babelica di cui parla Benjamin nel celebre intervento sul Compito del traduttore e in numerose altre occasioni. Saranno presi in esame anche altri testi dello scrittore modenese, principalmente dalla produzione in versi, tratti dalla raccolta Poesie della fine del mondo, del prima e del dopo; ma la riflessione non tralascerà anche i diari e le lettere di Delfini, cercando di offrire un ampio panorama della sua produzione.
The present paper aimed at showing the cognitive impact of the conceptual and perceptual organization of media on literary forms. On the one hand, McLuhan stated that the medium is a metaphor, as ...long as it shifts information across different conceptual domains. On the other hand, cognitive theories argued that the metaphor is a strategy of conceptualization of the experience. Mediology, cognitive poetics and literary criticism can cooperate in order to describe the conceptual metaphors conveyed by the media, and the way they interact with the literature in the deeply interconnected semiotic context of the XXth Century. Antonio Delfini’s writings and composition strategies reveal the hybridization produced by the contact between the rhetoric and the conceptual organization of literary texts, and the formal organization of the media. In Delfini’s work, the process of hybridization is realized by reusing textual fragments produced by media. Such an hybridization also consists in a wider phenomenon of exchange between the cognitive schemas produced by media, and the very idea of literature practiced by the author. Delfini, indeed, conceives the structures of newspapers and journals as a conceptual model for making sense of reality.
In Montale’s autobiographical book The Butterfly of Dinard, four short stories are devoted to the theme of opera singing learning. Art lives only thanks to the creators of undervalued works. Success ...is due only to a happy occasion that falls to the share of the few. The poet perceives the paintings of unsuccessful artists as living beings that brighten up his loneliness in the new mechanistic world. Unlucky singers, composers and artists are described with persistent empathy. Works of art serve as a link between the present and the past. The manner of A. Delfini, who created impressionistic sketches addressed primarily to the sensual perception of the reader, was understood and appreciated only post mortem. In the autobiographical story “One Story” Delfini explains the principles of his poetics to the reader, and doing it, he resorts to images of fine art. With the help of a well-known musical motif, he reveals the reason for his disappointment not only in the surrounding reality but also in himself. Thus, in the visual images of paintings and in the melodies of popular songs, he sees an opportunity to convey his personal perception of reality.
The Mucchi collection, kept at the Galleria Estense in Modena, represents a major heritage, of extreme relevance, in the still unexplored field of printing blocks.The set, made up of over 3400 pieces ...and ranging over a chronological period of five centuries, is here settled in a framework of great developments of the techniques of engraving, reproduction of images and the history of customs.After analyzing the general characters of the collection, which inextricably link it to the Soliani-Barelli collection conserved in the same museum, some thematic paths have been traced in view of a possible exhibition.In the collection we focused mainly on the work of Augusto Zoboli, a multifaceted character and artist from Modena in the early decades of the twentieth century, through which it is possible to examine the various techniques in use during a period of great typographic experimentation.

O ensaio discute a interpretação original de Giorgio Agamben sobre a obra do escritor italiano Antonio Delfini. Em particular, o ensaio analisa a centralidade da reflexão poética de Delfini no ...sistema estético agambeniano: a intransigência antimoderna de Delfini é, de fato, ligada por Agamben a uma reflexão geral sobre a natureza da palavra poética e relativa às mutações históricas da complexa relação entre obra e biografia na cultura literária ocidental. Nesse sentido, o ensaio reflete sobre o paralelo identificado por Agamben entre o significado profundo do conto Il ricordo della Basca e a ideia de uma “pura língua” pré-babelica falada por Benjamin em seu famoso trabalho na Tarefa do tradutor e em muitas outras ocasiões. Serão examinados também outros textos do escritor de Môdena, principalmente da produção em versos, escolhidos na coletânea Poesie della fine del mondo, del prima e del dopo; mas a reflexão não deixará de lado também os diários e as cartas de Delfini, buscando oferecer um panorama amplo de sua produção.
Interpreting isotopic ages as deformation ages when they are acquired from moderate-temperature metamorphic environments can be a challenging task. Syros Island (Cyclades, Greece) is famous for ...Eocene high-pressure metamorphic rocks reworked by localized Miocene greenschist-facies deformation. In this work, we investigate phengites from coarse-grained marbles, which experienced the high-pressure event, and phengites from fine-grained localized marble shear zones attributed to the low-grade Miocene deformation. Based on structural criteria, both events can be easily discriminated because of their opposing kinematics. Laser-heating 40Ar/39Ar analysis on phengite yielded a 40 ± 1.6 Ma age for the host rock and a 37 ± 1.3 Ma age for the shear zone. Both ages are statistically indistinguishable, consistent with the regional Eocene event, and not the Miocene deformation event responsible for the formation of the shear zone. Thermodynamic modeling indicates that the observed high-variance mineral assemblage is stable without compositional change along the pressure-temperature path followed by the rocks of Syros. Although the marble within the shear zone was deformed at extremely fast strain rates (10-10 s-1), we observed no intracrystalline deformation of phengite grains and no resetting in the isotopic system, because strain was mostly accommodated by calcite. Consequently, a high strain rate does not necessarily create deformation ages in rocks with high-variance assemblages, such as marble mylonites.
This article analyses the manner in which Dante's Vita Nova informs Antonio Delfini's collection Il ricordo della Basca (1938; 1956) and the novel by Gianni Celati, Lunario del paradiso (1978; 1989; ...1996), providing a thematic repertoire as well as a structural model. Reclaimed in the nineteenth century as the archetypal 'inner autobiography' and testimony of Dante's early loves, the Vita Nova is shown to be an effective model for exploring the connection between desire, memory and writing, a suitable filter - as in the cases of Delfini and Celati - for the narration of the wandering youth in search of an idealized and elusive love. At the same time, however, the anacronistic revival of the Dantean model is not without consequences: if in the Vita Nova, and subsequently in the Comedìa, Beatrice acts as a Master in the Lacanian sense - the law that guides Dante's entire human, spiritual and literary journey - it is modernity itself, for Lacan, that is placed beneath the sign of elision of the Master's discourse. This 'evaporation' of the Law is evident in works such as Basca and Lunario, 'modernity's Vitæ Novæ', and thus situates them in the realm of a wandering that is at the same time existential, erotic and textual.
Delfini’s way of writing is often tinged with intertextual quotations or allusions which prove to be functional within his work. In particular, the Poesie della fine del mondo, where the phenomenon ...acquires a status of unprecedented importance, are characterized by a kind of «teratology of quotation», which is peculiar to some Modernist texts. Intertextuality provides Delfini with a wide range of defensive as well as de-personalizing formulas, in a way akin to the more advanced contemporary poetry.
