The Logistics of Feeding the Roman Army on the Lower Danube 1 Page Stephen Richard Matthews A thesis submitted for the degree of PhD Department of Classics Royal Holloway University of London March 2018 1 2 Page 2 Part One 3 I Stephen Richard Matthews declare that this thesis and the work presented in it is Page entirely my own. Where I have consulted the work of others, this is always clearly stated. Signed Date 3 Acknowledgements My thanks go to my supervisor Professor Boris Rankov for his unstinting 4 Page support throughout. I would like to also thank Professor Richard Alston who read a full draft of the final thesis and Professor Jonathan Powell and Dr Christos Kremmydas, all of Royal Holloway who read sections of the text at various stages. Dr Ioana Oltean of the University of Exeter provided data gleaned through aerial imagery with which to work and was frequently willing to discuss my research; Dr Adriana Panaite, of the Institute of Archaeology “Vasile Pârvan” in Bucharest, provided advice with regard to the Roman road network. Finally I would acknowledge the tolerance of my wife and family – the youngest of whom has never known me do anything in my spare time but write this thesis. 4 Abstract This thesis sets out to quantify the logistical burden that a Roman garrison brought with it, in terms of land and transport requirements. The focus will be on 5 Page arable land, both to feed the soldiers but also to provide feed-barley for the transport animals. First the needs are quantified, having considered likely ranges of key variables that impact upon agricultural productivity. Then an appraisal of the arable available in the study areas is carried out on the basis of the settlement activity seen in the archaeological record. This is used to build a model of what land was plausibly available to supply the army. The study areas were selected according to where there had been previous landscape survey on the Lower Danube, around Novae and Nicopolis ad Istrum and also in Dobrogea, where it has long been assumed that settlement was encouraged to supply to the military. In this last case, my assessment of land available is carried out using the Romanian national database of sites – cIMeC – which aims to record all archaeological sites in the country. Although this is fraught with problems of interpretation, it is augmented both by works of traditional scholarship and by a dataset of tumuli for part of the region to arrive at a quantified, suggested solution to the needs of the garrison. For this suggested solution and the deficit – that part not available locally – the modelling of transport solutions is carried out. This is done within ArcGIS using the Service Area function, which allocates the most effective routes to move cargoes from producer to consumer. As a result models of what land was available and how the produce of that land was moved to the garrison are arrived at. 5 6 Page 6 Part One Weights and measures 14 Introduction 15 7 Page Chapter One: Preliminary considerations 1.1.1 Geography and demography 17 1.1.2 Summary of logistical knowledge and literature review 21 1.1.3 Research questions and methodology 34 1.1.4 Summation 41 Chapter Two: The needs of the garrison and the economics of supply Introduction 43 Chapter Two, Section One: How many men?
