Tradición constructiva y restauración

[EN] In view of the physical and material incompatibility of many restoration works performed in the past, in recent years there has arisen a debate about the wisdom of retrieving old building traditions for the restoration process with a simple mechanical interpretation. Professor Torsello dissects the concept of tradition as regards its relationship with experience, science, history and production to discover an order of problems that affect the structure of our knowledge and whose origin resides in the radical changes that characterise modernity.[ES] Constatada la incompatibilidad física y material de muchas restauraciones realizadas en el pasado, ha surgido un debate en los últimos años en torno a la bondad de recuperar las antiguas tradiciones constructivas para el proceso de restauración con una simple interpretación mecánica. El profesor Torsello disecciona el concepto y la pertinencia de la tradición constructiva en la actualidad, analizando el concepto de tradición a la luz de su relación con la experiencia, la ciencia, la historia y la producción, para descubrir un orden de problemas que afecta a la estructura de nuestro saber y cuyo origen reside en los cambios radicales que caracterizan a la modernidad.Torsello, BP.

La restauración de la arquitectura: cómo y por qué

[EN] With a magnificently clear mind, the author analyses the concept of restoration on the basis of his presuppositions, understanding architecture as a man-made artifice, containing memory and sustaining the passage of time. The restoration project implies choosing an act of will from among many possible options, seeking the survival, integrity and reuse of the work, a threesome of criteria in a committed balancing exercise that implies fulfilling all three components adequately.[ES] En un alarde de extraordinaria claridad mental, el autor analiza el concepto de restauración desde sus presupuestos de partida, entendiendo la arquitectura concebida como artificio creado por el hombre, portadora de memoria y sujeta al paso del tiempo. El proyecto de restauración implica la introducción de un acto de voluntad entre muchas opciones posibles que debe velar por la pervivencia, la integridad y la refuncionalización de la obra, una triada en un comprometido ejercicio de equilibrio que implica el cumplimiento conjunto y equilibrado de sus tres componentes.Torsello, PB.

From Restoration to Preservation; from Aesthetics to Ethics.

[EN] Torsello is one of the best qualified representatives of the current architectural restoration scene in Italy. In the article below, he sets out in a most persuasive manner the contradictions inherent in would-be definitive project interpretations concerning heritage. As opposed to the expression "know in order to conserve", he proposes "conserving in order to know", advocating techniques such as wall stratigraphy as a way of acquiring this knowledge.[ES] Torsello es uno de los más calificados representantes del panorama actual de la restauración arquitectónica en Italia. En el artículo que sigue expone de manera muy persuasiva las contradicciones inherentes a las interpretaciones proyectivas sobre el patrimonio que aspiran a convertirse en definitivas. Frente a la expresión “conocer para conservar” propone adjuntar la de “conservar para conocer”, abogando por técnicas como la estratigrafía muraria como vía de conocimiento.Torsello, BP. (1999).

Restauración e Historia: ¿Conflicto de intereses?

[EN] With great insight, the author examines the respective interests of the disciplines of restoration and history and the danger of a possible confusion, identification and overlapping of objectives. History understood in restoration as a set of guidelines, a building tool, a theatrical show or a monument to itself provides the keys to analyse and understand many works performed on architectural heritage of the past and the present.[ES] Con su aguda visión, el autor examina los intereses respectivos de las disciplinas de la Restauración y la Historia y los riesgos de una eventual confusión, identificación o superposición de objetivos. La historia entendida en la restauración en sus diversos casos como guía operativa, instrumento materializador, espectáculo teatral o monumento a sí misma proporciona claves para el análisis y la comprensión de muchas intervenciones en el patrimonio del pasado y del presente.Torsello, PB.

Notas sobre a Carta de Veneza

This paper presents a critical reading of the Venice Charter, an Icomos key document, fruit of a conference held in 1964. The Charter is often quoted in Brazil but is not always properly understood. The conservation and restoration charters - especially those produced by international institutions - are documents that have an indicatory or, at the most, prescriptive character. They constitute the deontological foundation of many professionals involved in preservation, but they are not recipes for immediate use. In order to elaborate a well-founded reading of the document, its ideas must be understood in connection to the theoretical postulates of the time they were engendered and to the developments of the field. Thus this paper will examine these subjects, commenting and enlightening the Charter's articles and pointing out the origins of specific ideas. It also discusses how the Charter relates to previous documents and their theoretical foundations. This approach, based in a critical analysis, is necessary in order to reach a fuller interpretation of the Charter's indications so that they can be used in the present

Second asymptomatic carotid surgery trial (ACST-2) : a randomised comparison of carotid artery stenting versus carotid endarterectomy

Background: Among asymptomatic patients with severe carotid artery stenosis but no recent stroke or transient cerebral ischaemia, either carotid artery stenting (CAS) or carotid endarterectomy (CEA) can restore patency and reduce long-term stroke risks. However, from recent national registry data, each option causes about 1% procedural risk of disabling stroke or death. Comparison of their long-term protective effects requires large-scale randomised evidence. Methods: ACST-2 is an international multicentre randomised trial of CAS versus CEA among asymptomatic patients with severe stenosis thought to require intervention, interpreted with all other relevant trials. Patients were eligible if they had severe unilateral or bilateral carotid artery stenosis and both doctor and patient agreed that a carotid procedure should be undertaken, but they were substantially uncertain which one to choose. Patients were randomly allocated to CAS or CEA and followed up at 1 month and then annually, for a mean 5 years. Procedural events were those within 30 days of the intervention. Intention-to-treat analyses are provided. Analyses including procedural hazards use tabular methods. Analyses and meta-analyses of non-procedural strokes use Kaplan-Meier and log-rank methods. The trial is registered with the ISRCTN registry, ISRCTN21144362. Findings: Between Jan 15, 2008, and Dec 31, 2020, 3625 patients in 130 centres were randomly allocated, 1811 to CAS and 1814 to CEA, with good compliance, good medical therapy and a mean 5 years of follow-up. Overall, 1% had disabling stroke or death procedurally (15 allocated to CAS and 18 to CEA) and 2% had non-disabling procedural stroke (48 allocated to CAS and 29 to CEA). Kaplan-Meier estimates of 5-year non-procedural stroke were 2·5% in each group for fatal or disabling stroke, and 5·3% with CAS versus 4·5% with CEA for any stroke (rate ratio [RR] 1·16, 95% CI 0·86-1·57; p=0·33). Combining RRs for any non-procedural stroke in all CAS versus CEA trials, the RR was similar in symptomatic and asymptomatic patients (overall RR 1·11, 95% CI 0·91-1·32; p=0·21). Interpretation: Serious complications are similarly uncommon after competent CAS and CEA, and the long-term effects of these two carotid artery procedures on fatal or disabling stroke are comparable
