Chapter Il suono della luce. Nuove narrazioni per il campanile di Santa Chiara a Napoli

The 43rd UID conference, held in Genova, takes up the theme of ‘Dialogues’ as practice and debate on many fundamental topics in our social life, especially in these complex and not yet resolved times. The city of Genova offers the opportunity to ponder on the value of comparison and on the possibilities for the community, naturally focused on the aspects that concern us, as professors, researchers, disseminators of knowledge, or on all the possibile meanings of the discipline of representation and its dialogue with ‘others’, which we have broadly catalogued in three macro areas: History, Semiotics, Science / Technology. Therefore, “dialogue” as a profitable exchange based on a common language, without which it is impossible to comprehend and understand one another; and the graphic sign that connotes the conference is the precise transcription of this concept: the title ‘translated’ into signs, derived from the visual alphabet designed for the visual identity of the UID since 2017. There are many topics which refer to three macro sessions: - Witnessing (signs and history) - Communicating (signs and semiotics) - Experimenting (signs and sciences) Thanks to the different points of view, an exceptional resource of our disciplinary area, we want to try to outline the prevailing theoretical-operational synergies, the collaborative lines of an instrumental nature, the recent updates of the repertoires of images that attest and nourish the relations among representation, history, semiotics, sciences

Massimiliano Ciammaichella, Scenografia e prospettiva nella Venezia del Cinquecento e Seicento. Premesse e sviluppi del teatro barocco, La scuola di Pitagora editrice, Napoli 2021

Introdotto da una Prefazione di Francesca Fatta, l’interessante volume monografico di Massimiliano Ciammaichella indaga le relazioni fra l’invenzione della scenografia a Venezia fra Cinquecento e Seicento e la scienza della prospettiva, articolando il tema in tre capitoli così denominati: La città dello spettacolo; La matematica dell’illusione; La scena barocca. Anticipati dall’Introduzione dell’autore, ai tre capitoli seguono le Conclusioni e la Bibliografia e fonti documentarie, sempre a firma di Ciammaichella. Dal punto di vista dell’impatto internazionale, l’Introduzione e la Conclusione sono interamente tradotte in lingua inglese mentre ai tre capitoli corrispondono ampie sintesi sempre tradotte nella suddetta lingua.Introduced by a Preface by Francesca Fatta, this interesting monographic volume by Massimiliano Ciammaichella investigates the relationship between the invention of scenography in Venice between the sixteenth and seventeenth centuries and the science of perspective, articulating the theme in three chapters: La città dello spettacolo (“The City of Spectacle”); La matematica dell’illusione (“The Mathematics of Illusion”); La scena barocca (“The Baroque Stage”). Preceded by the author’s Introduction, the three chapters are followed by the Conclusions and the Bibliography and Documentary Sources, again by Ciammaichella. From the point of view of international impact, the Introduction and the Conclusion are entirely translated into English, while the three chapters are each followed by an ample summary, also translated into that language

Between architecture and geometry Ovate experiments in Neapolitan tuff

[IT] Questa ricerca è dedicata allo studio della configurazione geometrica della scala come spazio rappresentativo dell’architettura. Questo contributo analizza una sorprendente scala, situata a Napoli (Italia) a Capodimonte, costruita in tufo (con sistema a sbalzo) e con sviluppo spaziale su una pianta a forma di cono rovescio. I metodi di indagine adottati sono stati il rilievo architettonico (diretto e con scanner laser) e l’analisi geometrica delle forme. I dati raccolti hanno permesso di riconoscere in questa scala la presenza di un grande pensiero progettuale capace di costruire una scala ovata a sbalzo nel tufo, adattando il suo sviluppo a un’elica conica invertita. Il modello della scala ovata è stato analizzato anche nei trattati di architettura italiana dal XVI al XVIII secolo.[EN] This research is dedicated to the study of the geometric configuration of the staircase as a representative space of architecture. This contribution analyzes an astonishing staircase, located in Naples (Italy) in Capodimonte, built in tuff (in a cantilevered system) and with a spatial development on an inverted cone-shaped plan. The investigation methods adopted were the architectural survey (direct and with laser scanner) and the geometric analysis of the forms. The data collected allowed to recognize in this staircase the presence of a cultured design thought capable of constructing a cantilevered ovate staircase in the tuff, adapting its development to an inverted conical helix. The model of the ovate staircase was also analyzed in Italian architectural treatises from the sixteenth to eighteenth centuries.Cirillo, V.; Zerlenga, O. (2020).

The open-well staircase of Palazzo Di Majo in Naples between geometry and equilibrium | La escalera de ojo abierto del Palacio Di Majo en Nápoles entre geometría y equilibrio

The staircases represent one of the most impressive architectural expressions of the building. Many authors presented a great deal of research over the years on this matter intending to understand how they are designed and laid out. This paper is concerned with a particular structural type of masonry staircase, known as stair with open well or roman staircase. It aims to demonstrate that in masonry-vaulted staircases, the close relationship between the shape and static behavior is particularly evident, and geometry and construction are essential for their stability. The authors have proved this statement by studying Palazzo Di Majo’s open-well staircase in Naples, whose main structure consists of tuff vaults. The first part of the article is substantially descriptive and presents an in-depth description of the geometric and architectural features of the stair. The second part explains all the aspects concerning the equilibrium of this kind of stairways, within Heyman’s theory of masonry

The majolica dome of Santa Maria della Sanità in Naples. Geometric configuration analysis and stability studies | La cúpula de mayólica de Santa Maria della Sanità en Nápoles. Configuración geométrica y estudios de estabilidad

This article deals with the survey and representation of the dome of Santa Maria della Sanità in Naples (Italy). The survey led to a geometric analysis of the spatial configuration of the dome, the drawing of its majolica decoration and its structural behavior. The overall objectives of this research can be briefly outlined as follows. First, the study focuses on defining the correct geometry of the dome obtained through accurate surveys. Finally, the study performs a simplified structural analysis of the compound dome-buttress system set within the theoretical framework of the Limit Analysis through the graphical statics

Varios autores han presentado muchas publicaciones a lo largo de los años sobre este tema para entender cómo han sido diseñadas y cómo se sostienen. Este trabajo se trata sobre un tipo específico de escalera de albañilería, conocida como escalera “de ojo abierto” o “a la romana”. El objetivo es demostrar que en las escaleras con bóvedas de fábrica existe una estrecha relación entre la forma y su comportamiento estático. La geometría y la construcción son imprescindibles para su estabilidad. Los autores han demostrado esta tesis estudiando la escalera de ojo abierto del Palacio Di Majo en Nápoles, cuya estructura principal está constituida por bóvedas de toba. La primera parte del artículo presenta una descripción detallada de las características geométricas y arquitectónicas de la escalera. La segunda parte, explica el equilibrio de estas escaleras a partir de la teoría del equilibrio de estructuras de fábrica de Heyman

Representing fortified architecture to narrate and enhance the Alexandrian territory border

[EN] The Piemonte cultural territory is also characterized by the significant presence of complex defensive systems, grouped by types and orographic configuration. Specifically,this paper will address asystematic and unitary re-reading of the territory of the Alessandria area, which includes: the sixteenth-century Cittadella di Casale, of the Gonzagas; the Citadel of Alexandria (1732), by Giulio Ignazio Bertola; Valenza and its fortifications (from the “Spanish” period with interventions by Gaspare Beretta, also interested in the fort / Castello Tortona); that of Gavi (restored “in the modern” by Gaspare Maculano known as Fiorenzuola, the friar who condemned Galileo). Following thirty years international research, the objectives of the work are twofold: the first aims to physically connect in this system a “network” of thematically dedicated tourist itineraries, through documentary paths that reconstruct historical events, construction phases and transformation, (in similitude with the ECCOFORT project, in the province of Verona). Following other works, by the authors already dedicated to the Alexandrian, through the advanced 3D modeling (like the one carried out in the reconstruction of the fort of Gavi) the second objective of the present contribution will follow the same restoring and reconstructive procedure. Through digitalized anastylosis, even dynamized, the Castle of Tortona will be rebuilt on the basis –among other things– of the conspicuous documentation (dated 1799, the year of the Napoleonic siege, followed by demolition, in 1801) found at the Osterreichisches Staatsarchiv, Kriegsarchiv of Vienna. The critical reconstruction is now made possible thanks to the precious wealth of knowledge, matured over the decades by Marotta, Zerlenga, Abello: with (indexed) data, including metrics, graphics and visual returns. Drawing between real and virtual, it will be possible to reconnect individual episodes, comparable and critically selected information, by means of congruently connected interventions, both physically and digitally. Finally, in a project of knowledge, conservation and valorisation, the “local” dimension dialogues and integrates with the European dimension.Marotta, A.; Cirillo, V.; Rabino, C.; Zerlenga, O.
