The hinterland of important centres like Petra (Southern Jordan) can provide essential information that contribute to the understanding of their rise, expansion and decline.

Local settlement system and social structure in the roman period at Oss (the Netherlands).

Casper de Jonge, Professor of Greek Language and Literature, believes that Greek texts from the Roman Empire are more interesting than was first thought. They offer a fascinating glimpse of the polyphonic and multicultural world of the Roman Empire. Inaugural lecture on 7 October.

Globalisation means becoming globalised, a process in which material culture plays a crucial role. This is what Miguel John Versluys, the new Professor of Classical and Mediterranean Archaeology, teaches. He bases his teaching on research into the origin and growth of the Roman Empire from the 3rd…

This research develops and applies a new approach to study Aegyptiaca Romana from a bottom-up, Roman perspective.

In 2017, in an ordinary field, two brothers from Brabant discovered more than 100 ancient coins. The Leiden historian who examined the coins concluded that they constituted a genuine Roman treasure. Here follows a reconstruction in three acts.

The project aims to conserve and consolidate the entrance gate to the Roman Desert Frontier Fort Qasr Bshir.

The first objective is to create a catalogue raisonée, i.e. a structured database that will store the main attributes of each town in a standardized format database, which will be freely accessible when completed; the second objective is to exploit theories and methods that can help us to understand…

This project suggests a reconceptualisation of pre- and non-capitalist imperial monetary policy, arguing that the existing literature about imperial financial flows has unnecessarily privileged ideas of largesse and seemingly chaotic monetary distribution.

Numismatic research of Roman coin hoards in the Netherlands. The use of numismatic sources is incorporated in Claes’s research project “Dialogues of Power”.

A semi-empirical version of the specific reaction parameter approach to density functional theory (SRP-DFT) has been remarkably successful at predicting dissociative chemisorption probability vs. incidence energy curves for reactions on metal surfaces. New quantum Monte Carlo (QMC) calculations on the…

The Aesernia Colonial Landscape project investigates ancient settlement patterns and dynamics around modern Isernia in Molise (Italy), the Latin colony of Aesernia (founded 263 BC). It consists of intensive systematic field survey in the territory of the colony, combined with remote sensing and geoprospection…

Our in-house human skin equivalents contain all stratum corneum (SC) barrier lipid classes, but have a reduced level of free fatty acids (FAs), of which a part is mono-unsaturated. These differences lead to an altered SC lipid organization and thereby a reduced barrier function compared to human skin.…

One of the objections to the Comprehensive Economic and Trade Agreement between Canada and Europe (Ceta) is that countries would be surrendering national sovereignty to multinationals which will obstruct effective climate policy. But compared to other trade agreements, CETA is an improvement.

The fragmentary is everywhere: we encounter fragments in social media (Tiktok, Twitter), in personal memories from our childhood, and in traditions from our cultural heritage.

The Archaeology of Imperial Landscapes examines the transformation of rural landscapes and societies that formed the backbone of ancient empires in the Near East and Mediterranean. Through a comparative approach to archaeological data, it analyses the patterns of transformation in widely differing imperial…

Soil ecologists Emilia Hannula (Leiden) and Elly Morriën (UvA) received the Golden Medal of Teylers Tweede Genootschap on 5 November. They received the prize for their submission to a competition on sustainable soil management.

This research cluster aims to analyse and interpret the formation and transmission of Graeco-Roman culture by exploring the relationships between cultural products (texts, objects, practices) and their societal and historical contexts.
