Difusió del patrimoni cultural a través de les TIC : el cas del portal de la vall de Boí

El portal de la vall de Boí és un projecte de col·laboració entre diferents museus, institucions i universitats de Catalunya amb l'objectiu de crear un entorn virtual per a incloure-hi tot el patrimoni cultural d'aquesta petita vall pirinenca. El portal no és tan sols un recurs potencial per al turisme cultural, sinó també un recurs d'art i d'història per a les escoles de secundària i les universitats, com també un mitjà de comunicació per a la comunitat local.The Boí valley portal is a joint project involving different museums, institutions and universities in Catalonia with the aim of creating a virtual environment to include all of the cultural heritage of this small valley in the Pyrenees. The portal is not only a potential resource for cultural tourism, but also an art and history resource for secondary schools and universities, as well as a means of communication for the local community

Novedades sobre la tipología de las ánforas Dressel 2-4 tarraconenses

The canonical name Dressel 2-4 had been used traditionally in scientific studies to nominate the most representative roman wine amphora from the High Roman Empire, especially those produced in the western Mediterranean basin. This is a generic and ambiguous definition including three Dressel CIL XV’s successive types. As we will see, this three types have different meaning, although a common economic function and a related design. Since 1971, when André Tchernia brought to the international community the existence of kilns in Catalonia to produce this kind of amphora, the concept of “Dressel 2-4 tarraconensis” become the standard denomination in almost all the studies published to date. To understand its raison d’être, the nature of the name, and its scientific limits as a typological classification, we start from a new, and yet necessary, general analysis of all the published data existing on the subject. The result of this work has been the construction of the first descriptive model to precisely date the Laietana amphorae. Finally, the systematization of evolutionary sub-types over time has revealed a change in the commercial dynamics of wines by the conjuncture “quality versus quantity”.El nombre canónico Dressel 2-4 se utiliza tradicionalmente en el argot científico para señalar a las ánforas vinícolas más representativas de época romana altoimperial, especialmente aquellas producidas en la vertiente occidental del Mediterráneo. Se trata de una definición genérica y al mismo tiempo ambigua que agrupa tres formas sucesivas de la tabla tipológica de Dressel en CIL XV, con una función económica común a través de un diseño afín, pero con valores diferentes, como vamos a ver, llenos de contradicciones. Desde que André Tchernia diera a conocer en 1971 a la comunidad internacional la existencia de hornos en Cataluña para producir esta clase de ánfora, el concepto de “Dressel 2-4 tarraconense” se ha convertido en una constante que encontramos, en la práctica, ejemplificada en la casi totalidad de los trabajos publicados hasta nuestros días. Para comprender su razón de ser, la naturaleza del nombre, y sus límites científicos como clasificación tipológica, hemos creído necesario llevar a cabo un nuevo análisis general de los datos publicados hasta ahora. Esta labor ha dado como resultado la confección del primer modelo descriptivo con el que poder datar las ánforas layetanas con precisión. Asimismo, la sistematización en el tiempo de sus variantes evolutivas ha hecho posible percibir un cambio en la dinámica comercial de los vinos por la coyuntura “calidad versus cantidad”

Los sellos in planta pedis de las ánforas olearias béticas Dressel 23 (primera mitad siglo V d.C.)

Despite the numerous literature on the production and consumption of Baetican olive-oil during the Principate, little is known about the survival of the Baetican amphorae in the Late Roman Empire. We present an epigraphic and economic study on a particular production of Dressel 23 amphorae, welldated in the first half of the Vth century A.D. It is a high value documental source, because it confirms objectively that a vivid trade continued under the political and religious rule of the primitive Christianism.Mucho se ha escrito sobre la producción y consumo de aceite bético en el marco histórico del Alto Imperio romano, pero muy poco se sabe sobre la pervivencia de las ánforas olearias béticas durante el Bajo Imperio. Presentamos el estudio epigráfico y económico de una producción particular de ánforas Dressel 23, bien datada y contextualizada en la primera mitad del siglo V d.C. Se trata de una fuente documental de gran valor para la investigación, porque gracias a ella podemos afirmar, con datos objetivos, que este comercio continuó ejerciendo un liderazgo significativo en una época de gran vitalidad comercial bajo la esfera política y religiosa del cristianismo primitivo

El consum de l'oli bètic a l'Empúries romana

Aquest article vol reflectir l'arribada d'oli d'oliva provinent de la província romana de la Bètica durant els tres primers segles de la nostra Era, (a la ciutat romana d'Empúries). Aquesta presència va ser a causa de l'encara destacada activitat comercial i portuària de la ciutat, que va participar en els principals circuits d'intercanvi econòmic de les províncies de l'Estat Romà

Arva : prospecciones en un centro productor de ánforas Dressel 20 (Alcolea del Río, Sevilla)

La campaña de excavación realizada en 1991 en las proximidades de sector termal de la ciudad romana de Arva (Alcolea del Río, Sevilla) ha permitido localizar tres hornos dedicados a la producción de ánforas Dressel20. Uno de ellos se data en época flavio-trajanea; los dos restantes se sitúan en un momento post-severiano. El conjunto parece formar parte del sector artesanal de Arva, situado junto al Guadalquivir.The 1991 season of excavations near the baths of the Roman city of Arva (Alcolea del Río, SevilIe) alIowed us to locate three pottery kilns especialized in the production ofDressel 20 amphorae. One of them was dated in the flavian-trajanean period.The remaining two were still active in the post -severian period. The whole area seems to be part of the craftmanship sector in Arva on the Guadalquivir river

Bayesian analysis and free market trade within the Roman Empire

The trade networks of the Roman Empire are among the most intensively researched large-scale market systems in antiquity, yet there is no consensus on the economic structure behind this vast network. The difficulty arises from data fragmentation and the lack of formal analytical methods. Here, the authors present a Bayesian analysis quantifying the extent to which four previously proposed hypotheses match the evidence for the market system in Roman olive oil. Results suggest that the size of economic agents involved in this network followed a power-law distribution, strongly indicating the presence of free market structures supplying olive oil to Rome. This new analysis offers an important tool to researchers exploring the impact of trade on the dynamics of past societies

The singular collection of tituli picti from the Ses Fontanelles shipwreck (Majorca, Balearic Islands) and its contribution to Hispanic late Roman amphoric epigraphy

In the summer of 2019, a Roman shipwreck with an amphorae cargo was discovered in Ses Fontanelles (SW of Mallorca). A rescue excavation has uncovered approximately a third of the materials, which are being studied. This paper focuses on the inscriptions (tituli picti) on the amphorae (mostly Almagro 51C), an exceptional find, given their high number as well as the type of writing. We analyze and relate paleography with other amphorae painted inscriptions in particular and epigraphical documents in general; we also relate the tituli with the content of the containers in their archaeological context and we approximate a prosopographical study of the anthroponyms that appear in the tituli. Finally, we link the cargo data with those of other imperial shipwrecks. Being quantitatively the most important corpus of painted amphoric epigraphy in Hispania, the wreck is revealed as a key piece to understand more clearly the socioeconomic history of the 4th century AD

What is cost-efficient phenotyping? Optimizing costs for different scenarios

Progress in remote sensing and robotic technologies decreases the hardware costs of phenotyping. Here, we first review cost-effective imaging devices and environmental sensors, and present a trade-off between investment and manpower costs. We then discuss the structure of costs in various real-world scenarios. Hand-held low-cost sensors are suitable for quick and infrequent plant diagnostic measurements. In experiments for genetic or agronomic analyses, (i) major costs arise from plant handling and manpower; (ii) the total costs per plant/microplot are similar in robotized platform or field experiments with drones, hand-held or robotized ground vehicles; (iii) the cost of vehicles carrying sensors represents only 5–26% of the total costs. These conclusions depend on the context, in particular for labor cost, the quantitative demand of phenotyping and the number of days available for phenotypic measurements due to climatic constraints. Data analysis represents 10–20% of total cost if pipelines have already been developed. A trade-off exists between the initial high cost of pipeline development and labor cost of manual operations. Overall, depending on the context and objsectives, “cost-effective” phenotyping may involve either low investment (“affordable phenotyping”), or initial high investments in sensors, vehicles and pipelines that result in higher quality and lower operational costs
