Carnuntum, well known for several hundred years as one of the most important sites for Roman coins in Europe, has repeatedly attracted the interest of numismatic scholarship. This volume presents the results of a major research project undertaken by the Numismatic Commission of the Austrian Academy of Sciences, in which nearly 40.000 coins from Carnuntum in the collection of the Museum Carnuntinum at Bad Deutsch-Altenburg were recorded and analysed. In addition to a catalogue of the material, included on a CD-ROM, the most important questions about the coin finds of Carnuntum are discussed in eleven extensive articles. The core of the publication is a statistical analysis of the findings, which with respect to the size of the sample has been unparalleled until now. In addition, a number of the contributions include material that looks beyond the local area. One chapter places the coin hoards from Carnuntum into the context of the whole region, and sheds new light on the question of the connection between hoarding practices and the incursions of the Marcomanni in the second century A.D. Another chapter of the book is dedicated to the history and coinage of the short-lived imperial couple Regalianus and Dryantilla. A special feature of Carnuntum and the Middle Danube region as a whole are the so-called Limesfalsa and iron core copies, which are presented here satisfactorily for the first time. Supplementary contributions deal with the local pre-Roman monetary history, with republican coins in imperial contexts, the influx of eastern provincial coinage and with coin circulation in the post-Roman period.
