“Soldiers of Christ” from the Byzantine Perspective: Monks,Emperors, and Conflict in the Early Byzantine Empire

This article is an exploration of concept of monks as “soldiers of Christ” in Byzantine Anatolia during the late sixth and early seventh centuries CE. Through a case study of Theodore of Sykeon, this article will explore monks as agents of continuity in the Byzantine Anatolia of the late sixth and early seventh centuries through Theodore's conflicts with the emperors, imperial authorities, and the regional episcopal hierarchy. The conflicts Theodore had with various authority figures of his time were about helping them see the right path of supporting Catholic orthodoxy as the normative belief system of Byzantine society and integrating his rural community of Sykeon into the wider web of imperial and episcopal urban patronage. Thus, conflict in this context was a catalyst for social order and stability rather than a symptom of social collapse. This article also fits into the historiography of the holy man as local patron in Late Antiquity, suggesting an alternate interpretation of this phenomenon as first put forward in Peter Brown's seminal works on this subject.     

New World States and Empires: Economic and Social Organization

We take a critical perspective in discussing recent publications on the archaeological study of the ancient state-level societies of Latin America. For some topics, such as intensive agriculture and exchange, data are far ahead of theory, whereas for others (e.g., gender and ethnicity), theory has outstripped data. Craft production, a topic that has achieved a good balance of data and theory, is one of the success stories of recent Latin American archaeology. After a discussion of sources of data, we review these and other topics (e.g., consumption patterns, household studies, social organization) in terms of both data and theory. In a second review article, we cover the topics of politics, religion, urbanism, and the processes of change.     

New World States and Empires: Politics, Religion, and Urbanism

The past decade has seen a veritable explosion in archaeological research on complex societies in Latin America. In 1993, Smith published an overview of research to that date; this article is one of two bringing that summary up to the present. Our first article, New World states and empires: Economic and social organization (Smith and Schreiber, 2005), dealt with issues regarding economic and social organization. The present article tackles political organization and dynamics, religion, urbanism, and settlement patterns. We also review recent research in the context of various theoretical perspectives, some traditional, some more contemporary, including approaches to history and process, cultural evolution, agency-based models, linguistic prehistory, migration theory, and the relationship between environmental change and cultural events. Our discussion blends empirical findings, methodological advances, and theoretical perspectives.     

Frankish military duty and the fate of Roman taxation

Frankish kings exacted unpaid military service from their subjects in both Merovingian and Carolingian times. The basis for this right has long been uncertain. A study of the term ‘manse’ as a Carolingian measure of assets brings to light the ostensibly hidden property on whose basis Franks went to war. This military duty reached back to the origins of the Frankish kingdom, when a large share of Roman taxes was awarded in individual allotments to soldiers obligated to serve, otherwise unpaid, when summoned, and heavily fined if they did not. Both demesne and tributary manses – contributory units – were the main part of state resources applied to military costs. They cannot be simply envisaged as components of an agricultural scheme (grand domaine). A tax‐like military obligation was one among several institutions actively surviving from the fifth century to the ninth, and it suggests that Frankish government was more law‐based and administrative than is often allowed.     

Allrounder braucht das (Entwicklungs-)Land Geographinnen und Geographen als Consultants in Entwicklungsl?ndern

Das Aufgabenfeld von Geographinnen und Geographen als Consultants in Entwicklungsl?ndern ist breit gef?chert: Die L?nder bieten dabei ein gro?es Einsatzgebiet und fordern andererseits enorme Einsatzbereitschaft. Eine Befragung von acht Personen sowie eine Analyse der Anforderungsprofile von im Consulting t?tigen Organisationen ergaben, dass Geographinnen und Geographen entscheidende Voraussetzungen für eine beratende T?tigkeit in Entwicklungsl?ndern erfüllen. W?hrend der geographischen Ausbildung erworbene Schlüsselqualifikationen sind unter anderem Kenntnisse verschiedener entscheidender Teildisziplinen und die F?higkeit zu interdisziplin?rem Denken und Handeln. Die Arbeit als Consultant in Entwicklungsl?ndern stellt somit für Geographieabsolventen eine interessante M?glichkeit und Chance auf dem Arbeitsmarkt dar.     

Fracture-fill calcite as a record of microbial methanogenesis and fluid migration: a case study from the Devonian Antrim Shale, Michigan Basin

The Devonian Antrim Shale is an organic‐rich, naturally fractured black shale in the Michigan Basin that serves as both a source and reservoir for natural gas. A well‐developed network of major, through‐going vertical fractures controls reservoir‐scale permeability in the Antrim Shale. Many fractures are open, but some are partially sealed by calcite cements that retain isotopic evidence of widespread microbial methanogenesis. Fracture filling calcite displays an unusually broad spectrum of δ¹³C values (+34 to ?41‰ PDB), suggesting that both aerobic and anaerobic bacterial processes were active in the reservoir. Calcites with high δ¹³C values (>+15‰) record cementation of fractures from dissolved inorganic carbon (DIC) generated during bacterial methanogenesis. Calcites with low δ¹³C values (13C values between ?10 and ?30‰ can be attributed to variable organic matter oxidation pathways, methane oxidation, and carbonate rock buffering. Identification of ¹³C‐rich calcite provides unambiguous evidence of biogenic methane generation and may be used to identify gas deposits in other sedimentary basins. It is likely that repeated glacial advances and retreats exposed the Antrim Shale at the basin margin, enhanced meteoric recharge into the shallow part of the fractured reservoir, and initiated multiple episodes of bacterial methanogenesis and methanotrophic activity that were recorded in fracture‐fill cements. The δ¹⁸O values in both formation waters and calcite cements increase with depth in the basin (?12 to ?4‰ SMOW, and +21 to +27‰ PDB, respectively). Most fracture‐fill cements from outcrop samples have δ¹³C values between ?41 and ?15‰ PDB. In contrast, most cement in cores have δ¹³C values between +15 and +34‰ PDB. Radiocarbon and ²³⁰Th dating of fracture‐fill calcite indicates that the calcite formed between 33 and 390 ka, well within the Pleistocene Epoch.
