The Tuscania Archaeological Survey investigated the archaeology of the countryside within a 10 km radius of the small town of Tuscania some 80 km northwest of Rome. The aim of the project was to contribute to present understanding of the processes that have shaped the development of the modern Mediterranean landscape as a physical and cultural construct. The specific research context of the project was debates about these processes in Etruria, the western side of central Italy that was the heartland of the Etruscan civilization in the mid first millennium BC: the character of prehistoric settlement prior to Etruscan urbanization; the relations between Etruscan towns and their rural populations; the impact on Tuscania and its landscape of being absorbed into the expanding Roman empire (‘Romanization’) and its economic structures after about 300 BC;the collapse of that system in the mid first millennium AD and the subsequent emergence of nucleated medieval villages (incastellamento); and the vicissitudes of peasant life through the political upheavals of medieval and post-medieval Italy. The chapter closes with an explanation of why we selected Tuscania and its intensively-farmed volcanic landscape as an ideal ‘laboratory’ for investigating this long-term landscape history, and how the project was planned.

This chapter documents the precipitous collapse of the fortunes of the papacy, and the Roman Church more generally, following the murder of John VIII in 882. A series of short-lived pontiffs must devote their energy to attempts to protect the city of Rome from physical assault, but the loss of any semblance of security in the surrounding hinterland leads to an economic collapse reflected in the archaeological record, the apparent absence of new building projects or significant gifts of precious objects, and also the discontinuation of the series of papal biographies (Liber pontificalis). The one exception is the Life of Stephen V (885–891), and this reveals the complete impoverishment of the papal treasury. The pope is reduced to making gifts of books, and this leads to a substantial discussion of what is known about book culture in Rome in the ninth century.

The Introduction sets out the methodological approach of the book, and the major themes to be addressed. It is a ‘history in art’, a notion that provides for a primary focus on the evidence adduced from material culture (archaeology, standing remains and their decoration, surviving objects including manuscripts) integrated with information derived from written sources (in this instance primarily the series of papal biographies known as the Liber pontificalis, supplemented by other documents such as the Ordines Romani and the chronicles of Frankish and Italian historians). The two other overarching themes are the gradual decline of the Roman economy, and the resulting impoverishment of the Roman Church over the course of the ninth century and its effects on papal patronage, and the continuing adherence of Roman artistic production to the broader context of Mediterranean Christian visual culture. A historiographical survey/analysis is also included.

Spanning much of the third quarter of the century, the pontificates of Benedict III (855–858), Nicholas I (858–867) and Hadrian II (867–872) reveal a declining papal involvement in the patronage of architecture, though also considerable engagement with ecclesiastical issues of the day, including dramatically renewed contacts with Constantinople and the eastern Mediterranean in the aftermath of the definitive end of Byzantine Iconoclasm and the ‘Triumph of Orthodoxy’. In addition to the growing importance of the Roman secular aristocracy, whose domestic housing has been rediscovered in recent archaeology, evidence is surveyed for the continuing presence of a substantial Greek community in Rome, and for interest in the translation of Greek texts in the circle of the papal librarian, Anastasius. Among the most prominent survivals from these years is the tomb of St Cyril, the Byzantine missionary to the Slavs, in the lower church of San Clemente.

This chapter surveys the engagement with material culture of three popes in the second quarter of the ninth century – Eugenius II, Gregory IV and Sergius II – spanning the years 824 through to 847. Although not as prolific as Paschal I in terms of patronage, all have left at least one significant project to have survived to the present day. Eugenius II’s marble clerical enclosure at Santa Sabina initiates a discussion of stone furnishings in Rome’s early medieval churches; Gregory IV’s apse mosaic in San Marco provides interesting insights into his participation in contemporary ecclesiastic politics in northern Italy, and other initiatives testify to continuing preoccupations with urban infrastructure and the cult of relics; and Sergius II’s newly reconstructed church of San Martino ai Monti attests to the continuing presence in Rome of significant teams of builders and decorators.

Our survey revealed very few sites belonging to the Early Medieval period (AD 700-1000) apart from Tuscania, indicating a combination of population decline and abandonment of the countryside for the security of the town. There was significant demographic growth in the High Medieval period (AD 1000-1200): 38 sites, together with 30 sites with ‘generic Medieval’ material likely to belong to this phase. The new foundations, distributed throughout the survey area, comprised nucleated but unfortified settlements, a habitation form about which the documentary record is largely silent. In the Late Medieval period (AD 1200-1500: 16 sites), new foundations were established within a few kilometres of Tuscania with little evidence for settlement in the countryside beyond. Most farmers preferred to live in defensible castelli, or within the vicinity of Tuscania. As elsewhere in Italy, the second half of the 2nd millennium has witnessed the increasing abandonment of many small farms by peasant (contadini) families in the face of urban growth and industrialization, with globalization in recent decades accelerating their replacement and absorption by agribusinesses, and the flight to the countryside by middle class commuters from Rome.

This brief ‘afterword’ draws together the various themes set out in the book, concluding that over the course of the ninth century the Roman Church goes from one of its highest points to what is arguably its medieval nadir. Some analysis is provided of the various factors which contributed to this dramatic decline.

No attempt to evaluate the longue durée of human settlement can ignore the environment as both a formative influence and as a cultural artefact. The environmental programme of the project collected data to complement the regional geomorphological and palynological record on patterns of landscape change in response to climate change and the influence of human activities. The geomorphological fieldwork focused on the catchment of the Marta river that flows from Lake Bolsena past Tuscania to the Tyrrhenian sea near Tarquinia. The Late Glacial environment c.15,000 years ago consisted of a steppe landscape.After a sedimentary hiatus in the Early and Mid Holocene, sediments started to be laid down again in the Later Etruscan period c.500-300 BC, reflecting the extensive nature of Etruscan agriculture.Significant human impacts began in the Roman Republican period. Then and during the Early/Mid Imperial periods the Marta and other rivers in the area were unstable braided and wandering gravel-bedded rivers quite unlike the modern rivers. Their dynamism largely reflected a colder wetter climate than today but also woodland clearance and increased arable cultivation.This combination pre-conditioned the landscape’s sensitivity to alluviation in the Late Medieval and Post Medieval periods.
