The frontier on the Middle and Lower Danube is one of the most important border regions of the Roman Empire and yet it has persistently been understudied within the broader genres of Roman frontier studies, Roman archaeology and ancient history. At long last, in recent years this has started to change—a welcome trend within which Timothy Hart’s Beyond the river: under the eye of Rome takes a prominent place. I wholeheartedly agree with the author’s point that among the frontiers, the Middle and Lower Danube “exerted [the strongest] influence over the cultural imagination and political destinies of the Roman empire” (p.8), and I also suggest that the intransient relevance of Roman frontiers to modern borders and borderlands further underlines the need for a better scholarly understanding of what may be the most consequential border landscapes of the Roman Empire.

Based on his PhD thesis of the same title from 2017, the monograph as a whole is thoughtfully structured, clearly written and suitable for students, researchers and the interested public. Centred on the geographical region of the Danubian Borderland, Hart’s work focuses on Rome’s “centuries-long effort to turn the Danube River from a natural source of movement and connection to a symbol of political and cultural separation” (p.6). This effort relied heavily on the use of ethnographic stereotypes, resulting in the perpetuation of topoi such as the Scythian Logos which homogenised the ‘barbarian’ peoples of the Transdanubian region and was employed to help with “justifying the establishment and maintenance of the Danube limes as an artificial boundary in a geographically connected land” (p.26). Deftly utilising archaeological and textual evidence (and disentangling dated arguments from various national research traditions), Hart illustrates how the peoples of the Danubian Borderland region interacted with the Romans between the first and fifth centuries CE. Perhaps the most valuable contribution of Hart’s work is the overwhelming evidence that we should not underestimate the lasting impact of contrived cultural constructs such as ancient ethnographic topoi—particularly when concerning the wielding of political power in border regions. Although this volume concerns the ancient past, there is a lesson here about imperial power and ‘othering’ that is undeniably relevant for our contemporary world.

The book is divided into two parts. Part 1 includes the Introduction and three chapters that, in the author’s words, seek “to investigate the natural and human forces that shaped the development of the Danubian Borderland in the first three centuries CE” (p.26), thus serving as a methodological framework for the following section. Part 2 (Chapters 4–7) presents three case-study chapters concerning the specific interactions of the Roman state with peoples north of the Danube from the fourth and fifth centuries CE and a conclusion. There are 23 figures supplementing the text—primarily maps drawn by the author, photographs of the landscape and of the Column of Marcus Aurelius. The figures are somewhat sparse at times, and more maps would have been a welcome addition.

The Introduction sets out the framework of the study, predominantly how the author understands the region of the Middle and Lower Danube as a borderland, rather than a frontier. Here, the genesis of the book from a PhD thesis becomes visible, yet there is also a lack of some of the elements one would expect to encounter, given the origins of the work. The theoretical discussions are a little cursory at times, particularly concerning borderlands studies, and the theorising of Roman frontiers and borderlands could have been expanded and updated—I was unable to find a reference to a source dating after 2016, with most from the 1990s and early 2000s. It would also be valuable to have the purpose, aims and general argument of the book stated more clearly at the outset. That said, the structure of the work and the author’s approach for re-evaluating “traditional ideas about barbarian migration and ethnogenesis” (p.25) through the lens of borderland processes are communicated well.

Chapter 1 focuses on the geography, climate and ecology of the Danube drainage basin, essentially providing the information necessary for understanding the geographical affordances of the region, which is bisected by the Carpathian Mountains. The subregions on either side of the mountain range are, nonetheless, connected by the Danube which fostered cultural exchange and mobility. Chapter 2 charts the development of the Scythian Logos, the necessary ideological support for the artificial boundary Rome imposed on the Danube, and outlines the consequences of this fundamental misunderstanding of the Scythians (particularly in the third century). Chapter 3 is a case study, drawing on archaeological evidence to “attempt as full a reconstruction as possible of life in the Roman-era Hungarian Plain” (p.129). This description of what Hart undertakes makes it sound deceptively easy; it most certainly is not, and the author should be commended for what they achieved in this chapter. Hart largely succeeds in detangling primary archaeological evidence from the “persistent, flexible, and deceptively strong tentacles of Greco-Roman ethnographic thought” (p.134) and the ethnonationalism of the past few centuries that had a significant impact on scholarship of the so-called ‘barbarian’ peoples.

Chapters 4, 5 and 6 are about the consequences of Rome’s stereotypical ideas concerning the peoples of the Transdanubian region. Chapter 4 discusses Aurelian’s withdrawal from Dacia, Constantine’s settling of the Tervingi Goths within the region, and how Constantine’s policy contributed to the spreading of a specific archaeological culture known in Romanian historiography as the Sântana-de-Mureş/Černajachov culture. Chapter 5 presents a reinterpretation of well-known events from Late Antiquity—namely, the military campaign of Emperor Valens against the Goths from 367–378, which concluded with the death of Valens at the Battle of Adrianople. Chapter 6 explores the aftermath of Adrianople and how the Scythian Logos persisted into the early medieval period, applied to successive waves of migratory peoples entering the Danubian Basin. Finally, a brief conclusion (Chapter 7) aptly summarises the complex series of events featured in the monograph and highlights the potential for further work.

At times more summative than critical, the author nonetheless presents a valuable study drawing on a complex arrangement of textual and archaeological evidence. Hart has set a benchmark for scholarship on the Danubian Borderland from the Iron Age to Late Antiquity, one that I hope will encourage similarly rigorous and comprehensive multidisciplinary studies of this consequential border region.
