Over the course of the last 120 years, around 32,000 antique coins have been found in the soil of the ancient city of Lauriacum, at the influx of the Enns into the Danube, most of which are held by the Museum Lauriacum in the city of Enns. Due to the quantity alone, but due in even greater measure to the importance of Lauriacum for Roman Austria, the coins found here number among the most important ancient cultural finds in Austria. They are one of the most significant primary sources for the history of Lauriacum as a military site, the intersection of multiple regional transport axes and as a late antique administrative centre and bishopric, providing unique insight into monetary transactions in the Danubian limes in Antiquity. In his historic-archaeological overview, Reinhardt Harreither traces the history of Lauriacum from the founding of the settlement in the middle of the 1st century, through the stationing there of the “legio II Italica” in around AD 190, right through to Late Antiquity and the early Middle Ages. The centrepiece of the volume is the numismatic evaluation by Klaus Vondrovec, in which all aspects of the circulation of money within Lauriacum are systematically recorded and analysed and their importance relative to other find locations determined. The coins found in the excavations from 1951 to 1959 in the ancient civilian town are subjected to a separate analysis by Anna Lörnitzo, while Bernhard Woytek comments on the Celtic strikes, the coins from the Roman republic and a selection of exceptional numismatic specimens. The volume is brought to a close by Nikolaus Schindel's commentary on the Byzantine exemplars. The digital catalogue can be accessed at https://doi.org/10.1553/Digitaler_Katalog
