Um espelho esmaecido: o reino visigodo de Toledo, cristianismo e monarquia

This paper aims to present some characteristics of Hispania in Late Antiquity and Early Middle Ages (4th-8th centuries). Search through a brief analysis of the relationship between Christianity and the Catholic Monarchy stood raise some issues and questions. We understand that Christianity has played and plays a significant role in the historical development of the Iberian countries. But in its installation and attempt to consolidation as hegemonic religion in the peninsula, faced several challenges. His alliance with the monarchy stood represented one of the ways to make stronger its dominance. In turn, the Monarchy, preserving its characteristic elective associated strongly with Christianity, giving him a theocratic character trying to raise the sovereign above the fray aristocratic, without much success. Thus, our text points to some of the paths followed by these two elements, Christianity and Monarchy at the time of the Kingdom of Toledo, proposing more reflections and ways that effectively covering them. We hope to have achieved it.

Studio analitico della cultura materiale fra VII e IX secolo d.C. nella Regione di Samarcanda (Uzbekistan): analisi morfo-tipologica, produzione e commercio della ceramica di Kafir Kala

Kafir Kala is a key-site to understand the historical dynamics of the Samarkand Region in the Early Middle Ages (5th - 8th centuries CE). The site is clearly associated with a Sogdian occupation, as both literature and archaeological research testify. But the chronological phase that follows the Sogdian period, as the Islamic occupation became stable, is still little known. Structures and finds (an hoard of 133 silver coins, in particular) clearly testify a new occupation of some parts of the citadel; and some rooms, dug in the northern side of it, present structures and materials connected with an Islamic activity. The study of material culture from these rooms, and from more ancient contexts, will help to understand the eventual continuity of traditions and the new productions. Besides the citadel, as a matter of fact, also some kilns have been dug, near the main site. Their material culture is very interesting because it represents an example of the typical Sogdian production (ceramics covered with white mica, and stamped). The work on the ceramic material has consisted in cataloguing and classifying all the diagnostics. Three main morphological classes have been individuated: cooking, coarse and table ware), and some other ones (lamps, ossuaries). A catalogue of the finds organized them in a typological system based on their morphology, function, fabric, and eventually decoration style. Crossing the stratigraphical data with information from this typological study, it has been possible to provide a chronological arrangement of the sites investigated by the italo-uzbek archaeological mission from 2001 to 2008.

Il cane e l'uomo nella cultura e nel diritto dell'alto medioevo

Attraverso l’indagine di fonti altomedievali come le Leges dei barbari si è potuto valutare, da un punto di vista pragmatico e fattuale, l’intenzione umana – a volte incidentale e pure difficoltosa – di inquadrare e definire il rapporto con un animale domestico come il cane, che continua e si evolve tra Antichità ed Alto Medioevo e senza una cesura netta. Per completare il quadro culturale e storico-sociale della ricerca, oltre alla trattatistica antica e alla letteratura medievale sugli animali, si è passato in rassegna espressioni documentarie come i capitularia mundana ed ecclasiastica, che hanno destato ulteriore interesse in quanto in esse sussiste il riflesso di un’attenzione tutta “altomedievale” per il cane e per quell’attività che da millenni lega l’uomo a questo animale: la caccia. L’argomento venatorio presuppone l’associazione con il cane nella quasi totalità dei provvedimenti sulla caccia, trasmettendo testimonianze stimabili del connubio homo cum canibus. Ne risulta ora un’amicitia, ora un legame impedito come nelle continue interdizioni venatorie rivolte agli ecclesiastici, uomini – e donne – di Chiesa che andavano a caccia. Pur non fornendo le stesse informazioni minuziose sui cani delle Leggi dei barbari, i capitularia propongono suggestivi scorci di un mondo in cui la caccia, forse la sola attività attraverso cui uomo e cane condividono le medesime trepidazioni primordiali, non era violenza gratuita ma un fondamento della cultura, soprattutto, ma non solo, di ambito aristocratico.

La città di Trento tra Tardo Antico e Alto Medio Evo: la genesi della città medievale e lo spazio del sacro.

Lo scavo della chiesa di Santa MAria Maggiore ha permesso di acquisire nuove importanti informazioni sulla storia della città di Trento, sulla città tardo antica e sul processo di cristianizzazione. Il primo impianto ecclesiastico, datato a dopo la metà del V d. C. secolo, sorge su un precedente impianto termale realizzato intorno al II secolo d. C. ed appare caratterizzato da un forte carattere monumentale. La chiesa, a tre navate, presentava un presbiterio rialzato decorato in una prima fase da un opus sectile poi sostituito nel VI secolo da un mosaico policromo. Sono state rinvenute inoltre, parti consistenti della decorazione architettonica di fine VIII secolo pertinente questo stesso impianto che non subirà importanti modifiche fino alla realizzazione del successivo edificio di culto medievale, meno esteso e dai caratteri decisamente meno monumentali, caratterizzato dalla presenza di un esteso campo cimiteriale rinvenuto a nord della chiesa. A questo impianto ne succede un terzo, probabilmente a due navate, e dalla ricca decorazione pittorica demolito in età tardo rinascimentale per la realizzazione della chiesa attuale.

Ravenna e i piu' significativi centri dell'Impero. Il mosaico parietale tra V e VI secolo: Revisione critica

Tra il V ed il VI secolo, la città di Ravenna, per tre volte capitale, emerge fra i più significativi centri dell’impero, fungendo da cerniera tra Oriente e Occidente, soprattutto grazie ai mosaici parietali degli edifici di culto, perfettamente inseriti in una koinè culturale e artistica che ha come comune denominatore il Mar Mediterraneo, nel contesto di parallele vicende storiche e politiche. Rispetto ai ben noti e splendidi mosaici ravennati, che insieme costituiscono senza dubbio un unicum nel panorama artistico dell’età tardoantica e altomedievale, nelle decorazioni musive parietali dei coevi edifici di culto dei diversi centri dell’impero d’Occidente e d’Oriente, e in particolare in quelli localizzati nelle aree costiere, si possono cogliere divergenze, ma anche simmetrie dal punto di vista iconografico, iconologico e stilistico. Sulla base della letteratura scientifica e attraverso un poliedrico esame delle superfici musive parietali, basato su una metodologia interdisciplinare, si è cercato di chiarire l’articolato quadro di relazioni culturali, ideologiche ed artistiche che hanno interessato e interessano tuttora Ravenna e i vari centri della tarda antichità, insistendo sulla pluralità, sulla complessità e sulla confluenza di diverse esperienze artistiche sui mosaici di Ravenna. A tale scopo, i dati archeologici e artistici sono stati integrati con quelli storici, agiografici ed epigrafici, con opportuni collegamenti all’architettura, alla scultura, alle arti decorative e alle miniature, a testimonianza dell’unità di intenti di differenti media artistici, orientati, pur nella diversità, verso le medesime finalità dogmatiche, politiche e celebrative. Si tratta dunque di uno studio di revisione e di sintesi sui mosaici parietali mediterranei di V e VI secolo, allo scopo di aggiungere un nuovo tassello alla già pur vasta letteratura dedicata all’argomento.

Prävalenz dentaler Pathologien vergangener und rezenter Bevölkerungen : dentalpathologische Untersuchungen an einem frühmittelalterlichen Reihengräberfeld aus Mannheim

Pathologische Veränderungen des stomatognathen Systems haben die Menschheit seit jeher geplagt. Etliche dieser dentalen Pathologien hinterlassen Spuren, die auch an Skelettmaterial noch erkannt werden können. Die vorliegende Studie beschäftigt sich mit der Aufnahme dentaler Pathologien an Skelettmaterial eines frühmittelalterlichen Gräberfelds aus dem Bösfeld in Mannheim. Hierbei werden die Individuen in Hinblick auf AMTL, PMTL, Karies, marginale Parodontopathien, periapikale Läsionen, Zahnabnutzung, Zahnstein und Hypoplasien untersucht. In Folge werden die Häufigkeit der Pathologien innerhalb verschiedener Untergruppen der Bösfelder Population und zwischen anderen zeitgleichen und rezenten Populationen verglichen.rnrnBei der Prävalenz von AMTL und Karies ist ein signifikanter Anstieg mit dem Alter der Individuen zu beobachten, während sich kein Unterschied zwischen den Geschlechtern ergibt. Marginale Parodontopathien sind signifikant weniger bei frühadulten Individuen zu finden als bei der Gruppe der über 30 Jährigen. In der Gesamtpopulation ergeben sich keine Unterschiede zwischen den Geschlechtern. Altersabhängig betrachtet sind jedoch die über 40-jährigen Männer signifikant häufiger von marginalen Parodontopathien betroffen, während bei der Altersgruppe der Frühadulten die weiblichen Individuen häufiger betroffen sind. Unabhängig von Geschlecht und Alter kann bei den marginalen Parodontopathien ein Zusammenhang zwischen den alveolaren Entzündungsreaktionen und dem Abstand zwischen Schmelz-Zement Grenze und Limbus alveolaris festgestellt werden. Die männlichen Individuen des Bösfelds sind signifikant häufiger von periapikalen Läsionen betroffen. Bei dem Zahnverschleiß wird ein solcher Unterschied zwischen den Geschlechtern nicht festgestellt. Lediglich eine Zunahme des Verschleißes mit dem Alter liegt vor. Auch der Zahnsteinbefall steigt mit dem Alter an. Ein Unterschied bei dem Zahnsteinvorkommen zwischen den Geschlechtern ist nicht zu finden. Nur die frühmaturen Männer zeigen im Vergleich zu den Frauen einen signifikant geringeren Befall. Diese höhere Zahnsteinablagerung bei den frühmaturen Frauen kann mit deren Eintritt in das Klimakterium erklärt werden. Die Hypoplasien des Enamels lassen ein durchschnittliches Entstehungsalter von 3 bis 4 Jahren erkennen. Dieses kann mit dem, im Frühmittelalter sehr späten, Abstillalter in Verbindung gebracht werden. Die an der Bösfelder Serie beobachteten Häufigkeiten der Patholgien sind zu einem großen Teil vergleichbar mit anderen zeitgleichen Skelettserien. rnrnDie vorliegende Studie gibt einen Einblick in die Epidemiologie dentaler Pathologien im Frühmittelalter, kann Rückschlüsse ziehen auf damalige Lebensumstände und kann Unterschiede zwischen damaliger und heutiger Prävalenz verschiedener Erkrankungen darstellen. Zukünftige Studien an der Bösfelder Skelettserie können mit einem Fokus auf die archäologische Auswertung der Grabbeigaben weitere Erkenntnisse liefern und so das Verständnis dieser merowingerzeitlichen Population vertiefen. rn

A 2600-year record of past polycyclic aromatic hydrocarbons (PAHs) deposition at Holzmaar (Eifel, Germany)

Polycyclic aromatic hydrocarbons (PAHs) are a proxy for climate- and human-related historical fire activity which has rarely been used beyond 1800 AD. We explored the concentration and composition patterns of PAHs together with other proxies (charcoal, C, N, S, δ13C, δ15N, and δ34S) in a sediment core of Holzmaar as indicators of variations in climate and anthropogenic activity over the past 2600 years. The concentrations of pyrogenic PAHs remained low (< 500 ng g− 1) from the pre-Roman Iron Age (600 BC) until the first significant increases to ca. 1000–1800 ng g− 1 between 1700 and 1750 AD related to regional iron production. The highest increases in pyrogenic PAH concentrations occurred with industrialization peaking in the 1960s. PAH concentrations in most recent sediments decreased to pre-industrial levels because of emission control measures and the switch from coal to oil and gas as major fuel sources. Fluxes of PAHs (mg km− 2 yr− 1) increased in the order Migration Period and Early Middle Ages < pre-Roman Iron Ages < Roman era < High Middle Ages and Renaissance < pre-industrial modern period < industrial modern period. The changes of PAHs fluxes in pre-industrial times parallel known changes in local, regional and continental anthropogenic activity and climatic variations or their interactions across these historical periods. Perylene, a mainly biologically produced compound, was the dominant PAH in pre-industrial times. The Migration Period and the Early Middle Ages witnessed the most profound and simultaneous changes to the sedimentary organic matter properties in the past 2600 years including the lowest PAH fluxes because of reduced human activity and more negative δ13C and δ15N values probably in response to colder and wetter conditions.

The role of human-induced fire and sweet chestnut (Castanea sativa Mill.) cultivation on the long-term landscape dynamics of the southern Swiss Alps

Changes in fire occurrence during the last decades in the southern Swiss Alps make knowledge on fire history essential to understand future evolution of the ecosystem composition and functioning. In this context, palaeoecology provides useful insights into processes operating at decadal-to-millennial time scales, such as the response of plant communities to intensified fire disturbances during periods of cultural change. We provide a high-resolution macroscopic charcoal and pollen series from Guèr, a well-dated peat sequence at mid-elevation (832 m.a.s.l.) in southern Switzerland, where the presence of local settlements is documented since the late Bronze Age and the Iron Age. Quantitative fire reconstruction shows that fire activity sharply increased from the Neolithic period (1–3 episodes/1000 year) to the late Bronze and Iron Age (7–9 episodes/1000 year), leading to extensive clearance of the former mixed deciduous forest (Alnus glutinosa, Betula, deciduous Quercus). The increase in anthropogenic pollen indicators (e.g. Cerealia-type, Plantago lanceolata) together with macroscopic charcoal suggests anthropogenic rather than climatic forcing as the main cause of the observed vegetation shift. Fire and controlled burning were extensively used during the late Roman Times and early Middle Ages to promote the introduction and establishment of chestnut (Castanea sativa) stands, which provided an important wood and food supply. Fire occurrence declined markedly (from 9 to 5–6 episodes/1000 year) during late Middle Ages because of fire suppression, biomass removal by human population, and landscape fragmentation. Land-abandonment during the last decades allowed forest to partly re-expand (mainly Alnus glutinosa, Betula) and fire frequency to increase.

Holocene vegetation development in the catchment of Sagistalsee (1935 m asl), a small lake in the Swiss Alps

Pollen and plant macrofossils were analysed at Sägistalsee (1935 m asl), a small lake near timber-line in the Swiss Northern Alps. Open forests with Pinus cembra and Abies alba covered the catchment during the early Holocene (9000–6300 cal. BP), suggesting subcontinental climate conditions. After the expansion of Picea abies between 6300 and 6000 cal. BP the subalpine forest became denser and the tree-line reached its maximum elevation at around 2260 m asl. Charcoal fragments in the macrofossil record indicate the beginning of Late-Neolithic human impact at ca. 4400 cal. BP, followed by a extensive deforestation and lowering of the forest-limit in the catchment of Sägistalsee at 3700 cal. BP (Bronze Age). Continuous human activity, combined with a more oceanic climate during the later Holocene, led to the local extinction of Pinus cembra and Abies alba and favoured the mass expansion of Picea and Alnus viridis in the subalpine area of the Northern Alps. The periods before 6300 and after 3700 cal. BP are characterised by high erosion activity in the lake's catchment, whereas during the phase of dense Picea-Pinus cembra-Abies forests (6300–3700 cal. BP) soils were stable and sediment-accumulation rates in the lake were low. Due to decreasing land-use at higher altitudes during the Roman occupation and the Migration period, forests spread beween ca. 2000 and 1500 cal. BP, before human impact increased again in the early Middle Ages. Recent reforestation due to land-use changes in the 20th century is recorded in the top sediments. Pollen-inferred July temperature and annual precipitation suggest a trend to cooler and more oceanic climate starting at about 5500 cal. BP.

Vestigios de latinidad clásica en reglas monásticas visigodas

Las reglas monásticas visigodas constituyen un corpus documental de importancia fundamental para el estudio del monacato primitivo en Hispania. Ellas reflejan, entre otros aspectos, la preocupación por los ideales de vida de su época, heredados en parte de diversos tratados clásicos, que expresaban, desde aspectos más profundos vinculados a la moral, hasta reglas más precisas relacionadas con el modo de comportamiento en sociedad. En la temprana Edad Media, esta preocupación fue retomada por las comunidades monásticas, rescatando elementos propios de las costumbres latinas tradicionales. En dicho contexto, este estudio se propone analizar la presencia de vestigios de latinidad clásica en las reglas monacales visigodas, las cuales sirvieron como receptáculo de aquellas tradiciones destinadas a regular los distintos aspectos de la vida del monje.

La competición en bandas armadas en Europa del Norte durante la Alta Edad Media

El presente artículo es un estudio sobre las actividades competitivas desarrolladas en el seno de las bandas armadas del norte de Europa en la Alta Edad Media: el juego, el reto y el combate, incluyendo los enfrentamientos violentos. Estas actividades no sólo eran una forma de pasatiempos, sino también aspectos muy importantes que revelan parte del funcionamiento de estas bandas. De hecho, podían representar desafíos para la cohesión de la comitiva, pero eran parte de su propia organización. Las comitivas eran dinámicas y sus estructuras siempre cambiaban, y las actividades competitivas, tanto las pacíficas y como las menos, definían y redefinían los rangos dentro del grupo

La inestabilidad política de los reyes visigodos de Toledo (s. VI-VIII) : Balance historiográfico y nueva propuesta de análisis

La inestabilidad política regia visigoda es un fenómeno tan constante en la documentación de los siglos VI-VIII que motiva una investigación para dar cuenta de sus principios estructurales. Se propone que la evolución política de la realeza visigoda corresponde a lógicas de funcionamiento de las aristocracias en sociedades de dominación incompleta, que expresan una dinámica general de la temprana Edad Media. Las opiniones de los autores sobre este fenómeno son tan variadas que se vuelve imperioso realizar un balance del estado de la investigación, detectar los problemas existentes y, lo más importante, delinear una línea de trabajo a seguir
