The study contains the latest knowledge concerning glass production at the beginning of the High Middle Ages in one of the oldest glass production areas in the Ore Mountains consisting of three glassworks located in the upper reaches of the mountains. The work presents archaeological sources obtained in excavations at the Jilmová I, II and III sites, with attention being focused on finds specific to glass production centres, i.e., mainly fragments of technical ceramics – melting pots, crucibles and the waste accompanying various stages of glass production. The classic typological­morphological analysis is accompanied by a detailed archaeometric analysis. The results of spectrometric analyses (XRF, XRD, SEM–EDS and LA–ICP–MS) expand the informative value of archaeological finds and help refine existing knowledge of glass production technology in the second half of the 13th century.

Insight Into

The Siete Partidas, compiled in the mid-13th century for the Castilian king Alfonso X el Sabio, constituted the code of law for Castile and later Spain.  Despite the practicality of their instructions and principles on warfare, they are not well studied.  This article will review the military provisions, paying special attention to commanders, the battlefield formations for infantry and cavalry, and the rules on booty and ransom, in the context of the time.  While it is difficult to pinpoint unequivocal influences, the passages are demonstrably practical within the contemporary military doctrine and the ideals of chivalry.  As such, they offer a unique insight into the mechanics of leadership, the battlefield formations of the High Middle Ages, as well as the crucial function of spoils as a source of status-compatible income for the knightly estate and lower nobility, so adding depth and texture to this little-studied yet essential aspect of mediaeval military, economic, and political organisation.

The 19Th Century

The origin of universities reaches the period of Ancient Greece when philosophy (sophists, Socrates, Plato, Aristotle, stoics and others) – the “Queen of sciences”, and the first institutions of higher education (among others, Plato’s Academy, Cassiodorus’ Vivarium, gymnasia) came into existence. Even before the new era, schools having the nature of universities existed also beyond European borders, including those in China and India. In the early Middle Ages, those types of schools functioned in Northern Africa and in the Near East (Baghdad, Cairo, Constantinople, cities of Southern Spain). The first university in the full meaning of the word was founded at the end of the 11th century in Bologna. It was based on a two-tiered education cycle. Following its creation, soon new universities – at first – in Italy, then (in the 12th and 13th century) in other European cities – were established. The author of the article describes their modes of operation, the methods of conducting research and organizing students’ education, the existing student traditions and customs. From the very beginning of the universities’ existence the study of law was part of their curricula, based primarily on the teaching of Roman law and – with time – the canon law. The rise of universities can be dated from the end of the Middle Ages and the beginning of modernity. In the 17th and 18th century they underwent a crisis which was successfully overcome at the end of the 19th century and throughout the following one.

Nitrate-nitrogen (N) losses in surface drainage and runoff water from ornamental plant production areas can be considerable. In N-limited watersheds, discharge of N from production areas can have negative impacts on nontarget aquatic systems. This study monitored nitrate-N concentrations in production area drainage water originating from a foliage plant production area. Concentrations in drainage water were monitored during the transition from 100% reliance on fertigation using urea and nitrate-based soluble formulations (SF) to a nitrate-based controlled-release formulation (CRF). During the SF use period, nitrate-N concentrations ranged from 0.5 to 322.0 mg·L−1 with a median concentration of 31.2 mg·L−1. Conversely, nitrate-N concentrations during the controlled-release fertilization program ranged from 0 to 147.9 mg·L−1 with a median concentration of 0.9 mg·L−1. This project demonstrates that nitrate-N concentrations in drainage water during the CRF program were reduced by 94% to 97% at the 10th through 95th percentiles relative to the SF fertilization program. Nitrate-N concentrations in drainage water from foliage plant production areas can be reduced by using CRF fertilizer formulations relative to SF formulations/fertigation. Similar results should be expected for other similar containerized crops. Managers located within N-limited watersheds facing N water quality regulations should consider the use of CRF fertilizer formulations as a potential tool (in addition to appropriate application rates and irrigation management) for reducing production impacts on water quality.

Governing Institutions

Historians of political development in the High Middle Ages often focus on the late twelfth and early thirteenth centuries as the generations in which monarchy finally triumphed over aristocracy to create a monopoly on governing institutions in Western Europe. However, it was precisely in this period that Simon of Montfort emerged from his modest forest lordship in France to conquer a principality stretching from the Pyrenees to the Rhône. A remarkable ascendancy in any period, it is perhaps especially so in its contrast with the accepted historiographical narrative. Despite the supposed triumph of monarchy during his lifetime, Simon’s meteoric career took place largely outside of royal auspices. Simon’s experience provides a challenge to an uncomplicated or teleological understanding of contemporary politics as effectively national affairs directed by kings.

Simon V of Montfort and Baronial Government, 1195-1218

Biographical Study

Dissenter from the Fourth Crusade, disseised earl of Leicester, leader of the Albigensian Crusade, prince of southern France: Simon of Montfort led a remarkable career of ascent from mid-level French baron to semi-independent count before his violent death before the walls of Toulouse in 1218. Through the vehicle of the crusade, Simon cultivated autonomous power in the liminal space between competing royal lordships in southern France in order to build his own principality. This first English biographical study of his life examines the ways in which Simon succeeded and failed in developing this independence in France, England, the Midi, and on campaign to Jerusalem. Simon’s familial, social, and intellectual connexions shaped his conceptions of political order, which he then implemented in his conquests. By analysing contemporary narrative, scholastic, and documentary evidence—including a wealth of archival material—this book argues that Simon’s career demonstrates the vitality of baronial independence in the High Middle Ages, despite the emergence of centralised royal bureaucracies. More importantly, Simon’s experience shows that barons themselves adopted methods of government that reflected a concern for accountability, public order, and contemporary reform ideals. This study therefore marks an important entry in the debate about baronial responsibility in medieval political development, as well as providing the most complete modern account of the life of this important but oft-overlooked crusader.

What meaning did human kinship possess in a world regulated by biblical time, committed to the primacy of spiritual relationships, and bound by the sinews of divine love? In the process of exploring that question, this book offers a searching re-examination of kinship in Europe between late Roman times and the high Middle Ages, the period bridging Europe’s primitive past and its modern present. It critiques the modernist and Western bio-genealogical and functionalist assumptions that have shaped kinship studies since their inception in the nineteenth century, when biblical time collapsed and kinship became a signifier of the essential secularity of history and a method for conceptualizing a deeper prehistory guided by autogenous human impulses. It argues that this understanding of kinship is fundamentally antagonistic to medieval sentiments and is responsible for the frustrations researchers have encountered as they have tried to identify the famously elusive kin groups of medieval Europe. It delineates an alternative ethnographic approach inspired by recent anthropological work that privileges indigenous expressions of kinship and the interpretive potential of native ontologies. The book reveals that kinship in the Middle Ages was not biological, primitive, or a regulator of social mechanisms; nor is it traceable by bio-genealogical connections. In the Middle Ages kinship signified a sociality that flowed from convictions about the divine source of all things and wove together families, institutions, and divinities into an expansive eschatological vision animated by “the most righteous principle of love.”
