The Roman province of Germania Inferior is characterized geographically by the river Rhine—the border of the Empire—and the forts along it. From the north-west to the south-east, there are significant differences in landscape and type of rural habitation. Whether these differences are also noticeable in animal husbandry forms the subject of this article. Are there any differences in species proportions and slaughter ages between the western and eastern parts of the province, and between urban, military, and rural sites? What does this say about farming and food supply? After presenting an overview of the zooarchaeological data from Germania Inferior, I shall discuss in detail one civitas—the civitas Batavorum, with the best known zooarchaeological dataset within the province. What changes in species proportions and cattle size can be detected over time from this civitas? Is there evidence for inter- and intra-site variability and changes in butchery methods? This article's further aim is to demonstrate what kind of questions a synthetic overview of zooarchaeological datasets can address.
