El retablo mayor de la catedral de Santa María de la Huerta de Tarazona (Zaragoza). Noticias sobre su realización. 1605-1614
Authors: Criado Mainar Jesús 
Published: March 2023

El retablo mayor (ha. 1605-1614) de la catedral de Tarazona (Zaragoza) es una de las expresiones más notables de la escultura policromada aragonesa de las primeras décadas del siglo XVII. Sufragado por el obispo fray Diego de Yepes (1599-1613), utiliza un lenguaje clasicista que se basa en el repertorio de inspiración romana trasladado por los artistas que realizaron el gran retablo mayor de la catedral de Astorga (León), conocido como romanismo.
Nuestro estudio revisa el proceso constructivo de esta gran máquina y aporta las condiciones de su policromía, contratada en 1613 con los pintores turiasonenses Agustín Leonardo y Gil Ximénez Maza. También analiza los contenidos de este documento ejemplar, en el que se describen de manera minuciosa tanto los procesos técnicos de aparejado, dorado y encarnado como las novedades introducidas por esos años en la fase del estofado.
La Mezquita Aljama de Córdoba
Authors: Souto Juan A. 
Published: March 2023

La Mezquita Aljama de Córdoba fue el monumento más emblemático del Islam andalusí. Sus génesis y desarrollo fueron un fiel reflejo de los avatares del Estado omeya a lo largo de su existencia en la Península Ibérica. El complejo lenguaje plástico, tanto arquitectónico como decorativo, plasmado en este edificio sirvió de modelo a construcciones islámicas occidentales contemporáneas y posteriores.
La presente contribución se pretende descripción sucinta e interpretación básica de las claves de este paradigma arquitectónico al hilo de la historia de al-Andalus entre los siglos VIII y X.
La metrología y sus consecuencias en los edificios de la Alta Edad Media Española. III: El Primer Románico en España
Authors: Esteban Lorente Juan Francisco 
Published: March 2023

Continuando los artículos anteriores, publicados en esta misma revista, nos vamos a ocupar de la arquitectura del llamado Primer Románico, los primeros setenta años del siglo XI. En este tiempo es la arquitectura lombarda la que define la estética y funcionalidad del diseño arquitectónico. En este momento, en las iglesias de tres naves, se inicia la conciencia de un espacio unitario, las referencias del diseño van al centro de los pilares. Lo más significativo es organizar los espacios de la planta de acuerdo a la geometría del triángulo equilátero. Estudiamos la metrología en las siguientes obras: las torres defensivas de Fantova, Loarre y Abizanda; las iglesias de San Caprasio en Santa Cruz de la Serós, la cabecera de Santa María de Ripoll, la catedral de Elna, Santa María de Obarra, San Vicente de Cardona, Sant Pere de Ponts, Sant Pere de Rodes, San Salvador de Leyre, Santa María de Alaón y Santos Pedro y Pablo de Cubillas en Urueña.
Fra Tardogotico e Rinascimento: Messina tra Sicilia e il continente
Authors: Scaduto Fulvia 
Published: March 2023

A menudo la arquitectura producida en el ámbito de Mesina entre los siglos XV y XVI se ha interpretado como ajena, con respecto al contexto de la isla. Probablemente haya que mitigar la imagen de Mesina como la ciudad más toscana y renacentista del Sur: seguramente los terremotos que afectaron de manera devastadora a Mesina y la Sicilia oriental sustrajeran numerosas pruebas de una prolongada permanencia del Gótico en esta área, condicionando inevitablemente la lectura de los historiadores. A esto habría que añadir que los palacios de Taormina se han fechado por error muy tempranamente, situándolos a principios del siglo XV. En realidad en estos episodios (y otros, como los de palacios de Cosenza) el lenguaje del Gótico tardío se manifiesta entre la Sicilia y la Calabria como un fenómeno vital que dura hasta al menos las primeras décadas del siglo XVI y se puede hallar en numerosas fábricas que la historia nos ha legado en restos o fragmentos de restos.
El Renacimiento aparece en el Noreste de Sicilia de la mano de escultores que emplean el mármol blanco de Carrara (activos sobre todo en Mesina y Catania) y se dedican a la realización de monumentos, altares, capillas, portales etcétera. Desde este punto de vista, Mesina sigue una parábola análoga a la de Palermo, donde la arquitectura tardogótica convive con la escultura renacentista. La influencia del clasicismo del mármol, de la tradición tardogótica y el debate originado en el duomo de Mesina, una obra que se estaba terminando todavía a principios del siglo XVI, parece producir en los centros de la provincia una serie de peculiares episodios en los que se experimenta la posibilidad de contaminaciones e hibridaciones (portales de Tortorici, Mirto, Mistretta, etc.).
Sobre todo la presencia en Mesina (desde 1528) de Polidoro da Caravaggio ocasiona un decidido viraje en dirección clasicista, introduciendo en la ciudad el lenguaje a la romana. La ciudad experimenta un poderoso cambio con la llegada de Carlos V (1535) y el debate que deriva representa un auténtico giro con respecto al resto de Sicilia.
Influencias italianas en la obra del escultor Pablo Serrano (1908-1985)
Authors: Ara Fernández Ana 
Published: March 2023

En este artículo pretendemos ahondar en las influencias que el escultor Pablo Serrano recibió de las obras de algunos de los artistas italianos más importante de su tiempo que tuvo ocasión de conocer durante sus viajes a este país.
Lucio Fontana, Pietro Consagra, Umberto Mastroianni o Sandro Cherchi, fueron artistas que debieron influir en que la producción del escultor español avanzara desde obras de corte tradicional hacia esculturas en las que las texturas, el hueco y el espacio adquirían valores definitorios.
Arquitectura al servicio de la devoción: las capillas del Santo Cristo y Nuestra Señora de la Soledad en la colegiata de Alcañiz (Teruel). 1579-1580 y 1698-1732
Authors: Martín Marco Jorge 
Published: March 2023

La llegada de las imágenes de un Cristo Crucificado y la Virgen de la Soledad a la colegial de Alcañiz (Teruel) en 1572 fue uno de los primeros casos de la presencia de esta devoción y del empleo del modelo ideado por Gaspar Becerra para el convento de mínimos de Madrid en Aragón. Para albergar las imágenes se construyó la primera capilla entre 1579 y 1580 que fue sustituida por la actual, trazada por Gaspar Serrano y materializada entre 1698 y 1732, ambas, edificadas en dos contextos arquitectónicos diferentes uno de otro.

Published: February 2023

This paper presents a critique of the traditional approach used to create a multiplayer game in the Unity real-time interactive application development system, especially in the case of a large number of concurrent users. As a hypothesis, an alternative option, which is not common, but which solves many of the problems of the previous approach, is proposed. Two client-server solutions have been compared for developing multiplayer online games in Unity, and the advantages of both approaches have been described for different cases. A game development architecture using a more up-to-date method is proposed: instead of the Mirror library, a standard toolkit for Unity development, microservices written in Golang are used. We present solid proofs of the preference of the alternative approach, the main advantage of which is the support of modern architecture providing high-speed communication between microservices, supported tests on messaging on different platforms.
The test results confirm the hypothesis put forth, and we can conclude that the Unity bundle with Golang is more effective for multiplayer video games.
The article also contains basic methods for debugging multi-threaded application in Golang bundled with Unity game development system and suggests a technological method that allows to get a fast way of data transfer between the client and the server.
