To what extent can Nietzsche's Amor Fati be seen as a Stoic concept?

This thesis presents the systematics, epidermal defense, and bioprospecting of wild orchids.

The main focus of this research project is to investigate why people in Eastern Arabia chose to reuse ancient tombs and how this can be linked to collective memory.

About 15 km to the south of the ancient city of Petra, archaeologists from the University of Leiden have discovered an impressive network of ancient water conservation measures and irrigated field systems.

New sampling and analytical strategies give archaeologists a better understanding of the nutrition and survival of ancient populations. Publication in PLOS One.

In the world of Ancient Greece the interpretation of supernatural signs was a versatile tool to facilitate decision-making. This is the central hypothesis of the PhD dissertation of historian Kim Beerden. Defence on 14 February.

Dr Bleda Düring deemed it was time for an archaeological approach on the imperialisation of Assyria. ‘While there are lot of archaeological studies of Assyrian sites, they are not really trying to address this broader picture of imperialism and how this imperialisation actually worked.’ These imperialisation…

In Renaissance Florence, humanists wrote Latin poems fashioning their city as the new Rome, and members of the Medici family as Roman rulers. How can we explain this practice?

Pyrotechnology – the manipulation and control of fire – is one of the defining characteristics of humanity, and has impacted nearly every technology that we used in the past and study archaeologically in the present. Our PhD researcher Femke Reidsma joined EXARC's podcast for May’s #FinallyFriday to…

The Persian Empire (539-330 BCE) was the first world empire in history. At its height, it united a territory stretching from present-day India to Libya - and it would take 2,000 years before significantly larger empires emerged in early modern Eurasia. This territorial sweep is both a source of fascination…

The human body consists of hundreds, perhaps thousands of different types of cells, each with different morphologies and functions, despite having the same genome.

This historical study argues that the Mandaean religion originated under Sasanid rule in the fifth century, not earlier as has been widely accepted. It analyzes primary sources in Syriac, Mandaic, and Arabic to clarify the early history of Mandaeism.

A unique archeological find near Tombos in Northern Sudan. Archaeologist Sarah Schrader from Leiden University, working with a team of international researchers, has discovered a grave of a ritually buried horse that is over 3000 years old. Both the grave and the skeleton are in perfect condition. The…

Taxonomy as a science has accumulated data and knowledge for more than 250 years.

What is the population size/structure and distribution of tiger and leopard inside the Bardia National Park (BNP) compared with the population outside? What is the movement and home range and conflict pattern in time and space of tigers and leopards inside the BNP compared with outside? What constitutes…

Leiden physicists and chemists have managed to bring two graphene layers so close together that an electric current spontaneously jumps across. In the future this could enable scientists to study the edges of graphene and use them for sequencing DNA with a precision beyond existing technologies. Publication…

“BABYLON” investigates the extent of the similarities between Babylonian and post-exilic forms of cultic and social organization and explores the question how Babylonian models could have influenced the restoration effort in Jerusalem.

This thesis studies the relationship of the town al-Fusṭāṭ, located at the southern end of the Nile delta in Egypt, and its hinterland in the period between the town’s foundation in A.D. 641 and the arrival of the Abbasids in 750.

In prehistoric times there was a huge wave of migration, from the steppes in Russia and Ukraine to West Europe. The newcomers’ genes began to dominate. Archaeology research in Leiden into burial mounds in the Veluwe and Utrechtse Heuvelrug areas of the Netherlands yielded this spectacular conclusion.…

Since the adoption of agriculture people have cultivated fields. The project concerns all kinds of aspects related to raising crops.

The material and intellectual presence of Egypt is at the heart of Western culture, religion and art from Antiquity to the present. This volume aims to provide a long term and interdisciplinary perspective on Egypt and its mnemohistory, taking theories on objects and their agency as its main point of…

How were ideas about politics and society distributed in ancient China? Hilde De Weerdt, Professor of Chinese History, investigates this using new digital methods. We speak with her about networks, big data and digital humanities.

In several Mediterranean regions archaeological sites have been mapped by fieldwalking surveys, producing large amounts of data. These legacy site-based survey data represent an important resource to study ancient settlement organization. Methodological procedures are necessary to cope with the limits…

A collaboration between the IBL and LUMC has resulted in the discovery that the polymerase theta enzyme is essential for the integration of Agrobacterium T-DNA into the genome of plants. The finding means a break-through for the development of more efficient systems for targeted genome modification…

Increasing the efficiency of gene targeting (GT) as a genome editing tool in plants has been an important goal in plant biotechnology.

Pakistani archaeologist Abdul Ghani Khan (MPhil) and Dr Marike van Aerde (Leiden University) have been awarded the Prince Claus Heritage Emergency Grant for the rescue and preservation of ancient rock art in the Karakorum mountain range of the Pakistani Himalayas. The project will run for a year, from…

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 thesis explores several aspects of these Early Old Babylonian Amorites.

Ahab Bdaiwi, University Lecturer of Islamic history, religion and philosophy, was received the first Faculty Impact Award. His interest lies in ‘everything that has to do with antiquity’, especially the religious and philosophical ideas that arose at that time. ‘They can move people. And many of those…
