This paper offers a re‐examination of some problems regarding the coinage of Vandal North Africa. The coinage of this barbarian successor state is one of the first non‐imperial coinages in the Mediterranean world of the fifth and sixth centuries. Based on the fine collection in the Coin Cabinet of Vienna’s Kunsthistorisches Museum, this art…[Read more]

Skepticism regarding the tree model has a long tradition in historical linguistics. Although scholars have emphasized that the tree model and its long-standing counterpart, the wave theory, are not necessarily incompatible, the opinion that family trees are unrealistic and should be completely abandoned in the field of historical linguistics has…[Read more]

Abstract and introduction for PhD dissertation, defended and deposited in April 2019.

Seit der frühen Neuzeit standen geschichtsmächtige Gruppen im Zentrum historischer Meistererzählungen. Vor allem die Umgestaltung der römischen Welt zwischen Antike und Mittelalter erklärte man durch die Wanderungen von Völkern, mit Dekadenzmodellen und konstruierten nationalen Charakteren. Meist wurde eine klare ethnische, kulturelle oder gar r…[Read more]

Some gentes–armed social units or peoples such as the Goths, the Franks, the Burgundians or the Vandals–became an intrinsic part of European history. Others like the Heruli, the Sciri, the Gepids and the Rugians played their somewhat vague role, but disappeared from our sources without having had the opportunity to form any stable regnum on…[Read more]

Studying North Africa poses a variety of problems. Historical as well as archaeological research bears the burden of a colonial view on Africa’s past tending to overemphasize its Roman aspects. Berber (Numidian and Moorish) political entities together with Punic (Carthaginian) cities had a long history when Rome entered the African scene. The h…[Read more]

This dissertation is a study of the usury prohibition in rabbinic literature. It focuses on the usury laws in Tannaitic literature, the first formulation of the usury prohibition as a complex and multifaceted judicial norm. I place the Tannaitic usury laws against the backdrop of the economic and cultural norms of the wider world which the Tannaim…[Read more]

Despite a period of almost two decades in which quantitative approaches in historical linguistics have been increasingly used, gaining constantly more popularity even among predominantly qualitatively oriented linguists, we find many problems in the field of computational historical linguistics, which have only sporadically been addressed. In the…[Read more]

By comparing the languages of the world, we gain invaluable insights into human prehistory, predating the appearance of written records by thousands of years. The traditional methods for language comparison are based on manual data inspection. With more and more data available, they reach their practical limits. Computer applications, however,…[Read more]

Original Abstract:
The sources for the history of Christianity in the early fourth century in the Persian Empire are notoriously sparse. And the sources that are available, such as the Demonstrations of Aphrahat, are vague and difficult to correlate with other sources. Historians of early Christianity have often incorporated these scant sources…[Read more]

This paper investigates the multiple impulses that contributed to the early medieval interest in Pope Damasus’s inscriptions. In part, Damasus’s verses were read as guides to Rome’s martyrial topography; in part, they served as models of a classicizing Christian style. Above all, the appeal of these verses derived from their association with…[Read more]

The paper deals with the so called griffin lamps. In the group of early Christian bronze lamps, a relatively large number of those with handles in the form of griffin-shaped protome have been preserved. Griffin lamps could be called the prototype of Late Antique production, owing to the manner in which stylistic and iconographic elements of the…[Read more]

Jewish relation to representational art is determined mostly by the Second Commandment: “You shall not make for yourself a carved image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; you shall not bow down to them nor serve them.” As science has observed, the…[Read more]

The aim of this research, focusing on representations of light and the symbolism of early Christian lamp decorations, has been to examine and summarise the existing knowledge of the symbolism of light in the Mediterranean region and the models by which this symbolism was manifested in the early Christian visual culture. Lamps with Early Christian…[Read more]
