Hydraulic structures of the Roman Mithraeum house in Augusta emerita, Spain

This paper deals with some of the hydraulic structures of Augusta Emerita (Mérida, Spain), specifically those found in the Mithraeum House. In particular, we describe and characterise the hydraulic mortars and coatings of the viridarium water channel. The recipient of the channel was covered with two hydraulic mortars and a finishing coating. Hydrated lime was used as binder. Calcite grains with different morphology have been observed in the mortars studied. The siliceous aggregate was composed of quartz, mica and feldspars. Ceramic fragments, which were added to the mortar to improve its hydraulic properties, were composed of quartz, mica, iron oxides, anorthite and an amorphous phase; aluminium-iron silicates were used as raw materials for their manufacture. We discuss the interactions between the hydrated lime and the surface of the ceramics in the mortars.     

Crop Fertility Conditions in North-Eastern Gaul During the La Tène and Roman Periods: A Combined Stable Isotope Analysis of Archaeobotanical and Archaeozoological Remains

ABSTRACT

Considerable archaeobotanical datasets describe cereal cultivation in north-eastern France, from the Iron Age to the Roman period. This study aims to complement these by using stable isotope analysis on charred cereal grains. Soil fertility was investigated through δ¹⁵N and δ¹³C analyses of 1480 charred cereal grains, dated from the Late La Tène to the Late Antiquity periods. In the Île-de-France, charred grain Δ¹³C values suggested good hydric conditions, with drier episodes in the 1st and 3rd century AD; while in Champagne, the lower Δ¹³C values for spelt reflect the lower water holding capacity of the chalky soils. A wide range of cereal δ¹⁵N values (0.8–8.7‰) implies a wide range of soil fertility conditions. Jouars-Pontchartrain and Palaiseau (Île-de-France) yielded the highest cereal δ¹⁵N values, whereas Acy-Romance (Champagne) delivered among the lowest. From these three sites, the δ¹⁵N values of red deer bone collagen were used to estimate the reference δ¹⁵N values for unmanured plants. Unlike in Acy-Romance, there were significant differences in Palaiseau and Jouars-Pontchartrain, indicating that the cultivated cereals inherited their high δ¹⁵N values from manured soil. At Jouars-Pontchartrain, the δ¹⁵N value (almost 9‰) suggested a high trophic level manuring source, possibly from pig and/or human faeces.     

The importance of difference in the making of transnationality: biographies and networks of the Benedictine mission in Tanganyika (1922–65)

The Missionary Benedictines of Saint Ottilien were the first Roman Catholic mission house in imperial Germany. During the heyday of European imperialisms, colonialisms and Christian missions the monastic community began its engagement in ‘German East Africa’. To enable and promote its proselytization efforts in the imperial colony until the end of the Great War, the Missionary Benedictines had to respond to shifting political conditions and to rearrange their networks as and when required. This orientation became even more pronounced during the renewal of the Benedictine Mission in the British mandated territory of Tanganyika up until the Second Vatican Council and the political independence of Tanzania. From 1922 to 1965 at least 379 members of the Congregation lived and worked in Tanganyika. Their biographies were closely linked to the complex transboundary system of their religious community. This article will portray them as a highly institutionalized group of transnational actors. It argues that to maintain its activities and organizational structures, the leaders of the Benedictine Mission established a dynamic multi-level network connecting a variety of scales, spaces and actors. To ensure its continued existence under constantly changing conditions they constituted a hierarchic system of difference and diversity.     

Political Culture in the Holy Roman Empire

This article reviews six essay collections and one monographon late medieval and early modern political culture in the HolyRoman Empire. Following a general survey of historiographicaltrends and a discussion of the specific contributions of theworks under review (covering topics from international relations,state formation and the role of language to representative assembliesand the exercise of power in towns and villages), it attemptsa preliminary sketch of the basic parameters of pre-modern politics.Prominent insights include shifts in the balance between oral,ritual and written communication, the significance of informalbonds and the negotiated quality of developments at all levelsof government. The conclusion assesses the potential of the‘new’ political history and calls for renewed effortsto link discourses, representations and perceptions to the norms,structures and socio-economic conditions with which they interacted.
