The 6th Potsdamer Lateintag took place in September 2010. It was part of the Brandenburger Antike-Denkwerk (BrAnD), a project funded by the Robert Bosch Foundation. The topic was ‘Roman Law’. Roman Law is a fascinating field of research. It is the background for the development of European law and is still continuing to have an effect. On the other hand it is one of those topics, which readers of Latin literature often come across but which may cause confusion, because the reader is not that familiar with this specific topic. The aim of the project was to fill this gap. Not only the legal background of the literary texts was to be examined, but also questions concerning the judicial regulation of everyday Roman life were studied. In addition to those academic questions pupils were requested to compare the ancient and modern legal systems. This volume includes the lecture given by Prof. Dr. C. Möller, a collection of sources to topics such as patria potestas, lex Aquilia, money and buy/exchange controversy, as well as reports on the whole project and on some of the school projects.
