Zwischen dem 5. und der Mitte des 6. Jahrhunderts bestand das Regnum der Vandalen und Alanen wie eine Reihe berberischer Territorien im römischen Nordafrika, welches sich in der althistorischen, mediävistischen und archäologischen Forschung zusehends als Testfall für ein besseres Verständnis der Umgestaltung der römischen Welt in Spätantike und Fr…[Read more]

We must, first of all, ask what a barbarian is or could have been in our sources. There were different kinds of barbarians, based upon the Roman and Greek ethnographic tradition and view of geography. Greek writers defined identities of human societies in the known world and bequeathed ethnonyms. Since the sixth and fifth centuries B.C.E., these…[Read more]

This essay will show, however, that the text is not linked to diplomas, but belonged to an African version of Prosper’s chronicle. I will propose a new edition, which will put the text back in its original context. Rather than looking for ‘good’ and ‘bad’ texts according to 19th-century categories, I will try to analyze the specific character…[Read more]

Das vandalische Afrika gilt als Musterbeispiel des „Kirchenkampfs“ zwischen homöischen Barbaren und katholischen Römern. Kronzeugen sind Victor von Vita, Fulgentius von Ruspe und Quodvultdeus von Karthago. Etwa 50 Jahre nach dem Ende der Vandalenkönige in Afrika 533 kam es in Spanien zum Ausgleich zwischen Katholiken und Homöern. Die westgot…[Read more]

The Vandal royal title Rex Vandalorum et Alanorum is known from the reign of king Huneric (477-484) from two decrees preserved in Victor of Vita’s History of the Vandal persecution. This catholic polemic pamphlet itself derives from the eighties or nineties of the fifth century. As traditional diplomatics throughout the 19th and 20th centuries c…[Read more]

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]

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]

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]

A book review of _Symbol and Icon: Dionysius the Areopagite and the Iconoclastic Crisis_ (Wipf & Stock, 2010), which extensively catalogs the severe lack of proper attribution of other scholars’ work in the book.

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]
