A major account of Renaissance portraiture by one of the
twentieth century's most eminent art historians In this
book, John Pope-Hennessy provides an unprecedented look at two
centuries of experiment ...in portraiture during the Renaissance.
Pope-Hennessy shows how the Renaissance cult of individuality
brought with it a demand that the features of the individual be
perpetuated, a concept first manifested in the portraits that fill
the great Florentine fresco cycles and led, later in the fifteenth
century, to the creation of the independent portrait by such
artists as Sandro Botticelli, Antonio del Pollaiuolo, Giovanni
Bellini, and Antonello da Messina. Pope-Hennessy goes on to
describe the process by which Titian and the great artists of the
High Renaissance transformed the portrait from a record of
appearance into an analysis of character.
Le recenti esposizioni dedicate a Giotto e a Dante offrono la possibilità di fare alcune considerazioni sul fenomeno delle mostre d’arte di ambito medievale. Per Giotto, il punto di partenza non può ...non essere l’esposizione del 1937 che, messa in risonanza con tutte quelle principali successive, contribuisce alla ricostruzione della stessa vicenda critica giottesca attraverso le differenti tradizioni di studi. Per Dante, il problema è la modalità con cui mettere in rapporto proficuo le vicende biografiche e letterarie con le esigenze espositive; il contributo offre un primo bilancio critico delle diverse proposte italiane in occasione del settimo centenario della sua morte.
Aims
The Italian Society of Interventional Cardiology (GIse) registry Of Transcatheter treatment of mitral valve regurgitaTiOn (GIOTTO) was conceived in order to assess the safety and efficacy of ...MitraClip therapy in Italy. The aim of this study was to assess procedural and mid‐term outcomes, and clinical and echocardiographic predictors of mid‐term mortality after MitraClip therapy, stratifying the results according to the diagnosis of functional and degenerative mitral regurgitation (FMR vs. DMR).
Methods and results
Between January 2016 and March 2020, 1659 patients were prospectively included in the GIOTTO registry (FMR 59.4% vs. DMR 40.6%). Acute Mitral Valve Academic Research Consortium (MVARC) technical success was achieved in 97.2% of patients, without differences between FMR and DMR and with sustained results at 30 days. In the study population, all‐cause mortality was 4.0%, 17.5% and 34.6% at 30 days, 1 year and 2 years, respectively. Cardiovascular death was the most frequent cause of mortality. Overall hospitalization rates were 6.3%, 23.4% and 31.7% at 30 days, 1 year and 2 years, respectively. The most frequent cause of hospitalization was heart failure, particularly in the first 30 days. FMR and MVARC structural and functional failure were strongly associated with 1‐year mortality. Residual mitral regurgitation 1+ (rMR) was independently related to a reduced risk of 1‐year mortality (hazard ratio 0.62; P = 0.005). Coherently, at 2‐year follow up, FMR was associated with worse outcomes than DMR, and Kaplan–Meier all‐cause mortality was related to rMR.
Conclusions
Functional mitral regurgitation aetiology affects 1‐year mortality after MitraClip implantation, and differences in mortality and hospitalization rates between FMR and DMR can be observed within 2 years. Optimal rMR 1+ was correlated to a more favourable mid‐term outcome, particularly in FMR.
Il contributo analizza, attraverso le parole del suo stesso ideatore, il progetto di allestimento della mostra Giotto, l’Italia a Palazzo Reale di Milano (2 settembre 2015-10 gennaio 2016), ...realizzato dallo studio Mario Bellini Architects dando vita a una “macchina scenica” altamente suggestiva e al contempo attenta tanto alla dimensione conservativa, quanto alla lettura contestuale dei capolavori del maestro toscano.
In situ research of cometary chemistry began when measurements from the
Giotto
mission at Comet 1P Halley revealed the presence of complex organics in the coma. New telescopes and space missions have ...provided detailed remote and in situ measurements of the composition of cometary volatiles. Recently, the
Rosetta
mission to Comet 67P Churyumov-Gerasimenko (67P) more than doubled the number of parent species and the number of isotopic ratios known for comets. Forty of the 71 parent species have also been detected in pre- and protostellar clouds. Most isotopic ratios are nonsolar. This diverse origin is in contrast to that of the Sun, which received its material from the bulk of the collapsing cloud. The xenon isotopic ratios measured in 67P can explain the long-standing question about the origin of terrestrial atmospheric xenon. These findings strengthen the notion that comets are indeed an important link between the ISM and today's solar system including life on Earth.
Nonsolar isotopic ratios for species such as Xe, N, S, and Si point to a nonhomogenized protoplanetary disk from which comets received their material.
The similarity of the organic inventories of comets and presolar and protostellar material makes it plausible that this material was accreted almost unaltered by comets from the presolar stage.
Large variations in the deuterium-to-hydrogen ratio in water for comets indicate a large range in the protoplanetary disk from which comets formed.
The amount of organics delivered by comets to Earth may be highly significant.
Las imágenes de san Francisco de AsÃs se multiplican en Europa con la función de servir de modelo a los frailes menores y despertar la veneración de los fieles mediante el conocimiento de los ...episodios más significativos de su hagiografÃa. Para comprender el significado último de estas representaciones es necesario recordar dónde fueron realizadas, aunando aspectos formales y fuentes literarias que sirvieron de inspiración a los pintores de la Baja Edad Media. En las siguientes lÃneas veremos el importante papel de los franciscanos como comitentes, la difusión de las biografÃas de Tomás de Celano y san Buenaventura y su recepción en las imágenes, especialmente, a partir de los frescos de Giotto di Bondone en AsÃs.
The article examines Dante Gabriel Rossetti’s watercolor "Giotto Painting the Portrait of Dante". The painting is the result of several artistic and literary quotations, being originally conceived as ...an interplay of anecdotes, literary texts, and works of art. While evidently based on "Purgatorio" XI, the painting also to passages in the "Vita Nuova" as well as to frescoes in the Palazzo del Bargello and in Santa Maria Novella that Rossetti was probably familiar with.
