Corruption is a concept that is frequent and present in our daily lives, on the media as well as in private conversations. At the same time, however, the term is difficult to define with precision. The concept of corruption includes a broad series of conducts perceived and/or defined as illicit, illegitimate or immoral. The common feature of these behaviours seems to be their configuration as principal-agent problem. But, among other things, it is particularly complex to disentangle the moral connotation of the term, understood as degeneration and decay, from its legal and political meaning. This is mainly because the significance of the concept in media and public opinion depends very much on the connection of both sides. The book series "Twisted Transfers" features studies that examine all possible facets of corruption in the ancient world, including ancient global and comparative approaches to the phenomenon: How was corruption perceived in ancient periods in different parts of the world? How were anti-corruption laws and measures developed? How is corruption discussed in ancient sources, and how did such discourses shape the political and social life of ancient communities? These are just some of the key questions that this series aims to answer.
