The volume presents phenomena of classification and categorisation in ancient and modern cultures and provides an overview of how cultural practices and cognitive systems interact when individuals or larger groups conceptually organize their world. Scientists of antiquity studies, anthropologists, linguists etc. will find methods to reconstruct early concepts of men and nature from a synchronic and diachronic comparative perspective.

Ancient cultures have left written evidence of a variety of scientific texts. But how can/should they be translated? Is it possible to use modern concepts (and terminology) in their translation and which consequences result from this practice? Scholars of various disciplines discuss the practice of translating ancient scientific texts and present examples of these texts and their translations.

Medicine, astronomy, dealing with numbers a ' even the cultures of the a oepre-moderna world offer a rich spectrum of scientific texts. But how are they best translated? Is it sufficient to translate the sources into modern scientific language, and thereby above all to identify their deficits? Or would it be better to adopt the perspective of the sources themselves, strange as they are, only for them not to be properly understood by modern readers? Renowned representatives of various disciplines and traditions present a controversial and constructive discussion of these problems.

Since the dawn of humanity, people have developed concepts about themselves and the natural world in which they live. This volume aims at investigating the construction and transfer of such concepts between and within various ancient and medieval cultures. The single contributions try to answer questions concerning the sources of knowledge, the strategies of transfer and legitimation as well as the conceptual changes over time and space. After a comprehensive introduction, the volume is divided into three parts: The contributions of the first section treat various theoretical and methodological aspects. Two additional thematic sections deal with a special field of knowledge, i.e. concepts of the moon and of the end of the world in fire.
