Facies, depositional environment, and palaeoecology of the Middle Triassic Cassina Beds (Meride Limestone, Monte San Giorgio, Switzerland).

The Ladinian Cassina beds belong to the fossiliferous levels of the world-famous Middle Triassic Monte San Giorgio Lagerstatte (UNESCO World Heritage List, Canton Ticino, Southern Alps). Although they are a rich archive for the depositional environment of an important thanatocoenosis, previous excavations focused on vertebrates and particularly on marine reptiles. In 2006, the Museo Cantonale di Storia Naturale (Lugano) started a new research project focusing for the first time on microfacies, micropalaeontological, palaeoecological and taphonomic analyses. So far, the upper third of the sequence has been excavated on a surface of around 40 m(2), and these new data complete those derived from new vertebrate finds (mainly fishes belonging to Saurichthys, Archaeosemionotus, Eosemionotus and Peltopleurus), allowing a better characterization of the basin. Background sedimentation on an anoxic to episodically suboxic seafloor resulted in a finely laminated succession of black shales and limestones, bearing a quasi-anaerobic biofacies, which is characterized by a monotypic benthic foraminiferal meiofauna and has been documented for the first time from the whole Monte San Giorgio sequence. Event deposition, testified by turbidites and volcaniclastic layers, is related to sediment input from basin margins and to distant volcanic eruptions, respectively. Fossil nekton points to an environment with only limited connection to the open sea. Terrestrial macroflora remains document the presence of emerged areas covered with vegetation and probably located relatively far away. Proliferation of benthic microbial mats is inferred on the basis of microfabrics, ecological considerations and taphonomic (both biostratinomic and diagenetic) features of the new vertebrate finds, whose excellent preservation is ascribed to sealing by biofilms. The occurrence of allochthonous elements allows an insight into the shallow-waters of the adjoining time-equivalent Salvatore platform. Finally, the available biostratigraphic data are critically reviewed.

Giorgio Strehler y 'Le nozze di Figaro de Mozart' : el tema de la ópera a través de su puesta en escena.

Constatar que hay una verdad en la obra de arte que se analiza y ver cómo esta verdad se interpreta en la puesta en escena de Giorgio Strehler. En la primera parte se ha determinado las diferencias en cuanto a las adaptaciones de los actos de la comedia a la ópera y la presencia y uso de los códigos propios de la opera buffa. En la segunda se ha realizado un análisis musical de la partitura de la ópera, siguiendo los números musicales de cada acto y escena. Se han descrito los elementos del lenguaje musical siguiendo los números musicales de la partitura en sus cuatro actos. El análisis de la puesta en escena de Giorgio Strehler se ha realizado teniendo en cuenta la misma metodología para el análisis del tema de la ópera, pudiéndose comprobar si el tema de la opera se encuentra modificado en la puesta en escena de Strehler. Desde el nacimiento de la ópera y durante la sucesión de distintas etapas evolutivas de la dramaturgia musical se puede constatar que existe una permanente búsqueda de la verdad; El pensamiento filosófico de las distintas épocas así como determinados acontecimientos históricos, han influido en la ópera como realidad artística; La relación de superioridad o inferioridad entre la palabra y la música está presente en toda la evolución de la dramaturgia musical y de la ópera; Gracias a la consideración de aspectos netamente musicales y de otros conceptos que provienen de la tradición teatral, así como la natural evolución de la ciencia (incorporación de luz a los escenarios) se han originado determinadas concepciones escénicas de gran importancia para la comprensión y evolución de la dramaturgia musical y de la puesta en escena de la ópera; El estudio de la evolución de la dramaturgia musical desde el Renacimiento hasta el Siglo XIX, así como de las distintas influencias que determinan su desarrollo y puesta en escena hasta el Siglo XX, nos muestran la importancia que tiene dentro del marco la formación estética de la persona; Las distintas artes que se articulan en la ópera se han ido incorporando de forma constructiva, de forma que la interrelación entre todas ellas ha generado una sólida estructura dramática en cuyo núcleo se encuentra el tema de la obra. En la opera se desarrolla un plan pedagógico propio utilizando los recursos musicales de su época y a través de la dramaturgia musical .

Bare life in second life : Giorgio Agamben's politics in performance

This paper describes and analyzes the necessary misreadings of Giorgio Agamben’s account of ‘bare life’ in a recent performance in Melbourne, Australia. The ‘Bare Life’ project deals with Australia’s treatment of asylum seekers with reference to Agamben’s work on sovereign power and uses the on-line second life world as both a metaphor for the refugee’s desire for a new life, and a literal site of performance. The development showing explored the interactions between live performance and second life avatars in real time. This paper deals with the philosophical, ethical and practical problems that emerged during the development, and argues that the ‘misreading’ is an inevitable, but useful part of finding ways to embody philosophical and political ideas in performance.

Giorgio de Chirico and the idea of enigmatic imagery : the innocence of becoming

My paintings emerge from within a context best explained by reference to Nietzsche's perspectivism. That is an intellectual attitude that deprivileges rationalism and accommodates scepticism or unknowing as an acceptable starting point From this standpoint art/language can be seen as being in a state of becoming rather than as representing a state of being. This thesis aims to demonstrate, not only by a philosophical encounter with Giorgio de Chirico's work: ie. his use of myth, his Nietzschean perspectivism and his enigmatic interpretation of figuration, that the most helpful context and understanding of my work can be realied. De Chirico's art, like Nietzsche's philosophy seeks in its processes to explore the possible unity of Dionysian aesthetic force with the Apollonian. Neither Nietzsche nor de Chirico considered within a post-Socratic world that this unity was realizable. Nevertheless they both share in their respective art forms a need to represent the relentless struggle to enact the disjunction of the two aesthetic forces in a secular world. The artist’s enigmatic imagery is characterized by a consideration of appearance and reality and it is for this reason that the work was selected as a model for investigating the nature of enigma. His use of seemingly straightforward, ordinary images suggests a sense of accessibility, yet at the same time they are irreducible to knowing and my own image-making was greatly expanded by investigating these concerns. I am not arguing that de Chirico was influenced by Nietzsche but instead that Nietzsche's philosophical point of view and his use of poetic language to express these views lay in discovering the qualities and substance of the Dionysian spirit As well as working within a Nietzschean world-view set out in The Birth of Tragedy, de Chirico has also drawn on the Italian unification, specifically the Risorgimento and the lineage of these political and mythical figures were endemic to his art and they interface the with his use of the Apollonian-Dionysian disunity first explored by Nietzsche. The focus of the exegesis will be to present the poetic and philosophical use made of the latter in de Chirico’s art It is anticipated that this philosophical encounter with the aesthetic, social and political world of de Chirico will, not only assist in interpreting his life's work anew, but will also provide a context in which my paintings of enigma might be interpreted.
