Grossi, Joseph L, Jr. Uncommon Fatherland: Medieval English Perceptions of Rome and Italy (John Lydgate, John Capgrave, Anglo-Italian Relations) Ohio State University. Ph. D. Dissertation Advisor Christian K. Kacher. 1999. Summary: This dissertation argues that late medieval English literature depicts Rome and Italy with the same cultural anxieties found in works that imagine the Muslim world. Although partially Orientalizing Rome and Italy, however, the alliterative Morte Arthure, John Lydgate's Fall of Princes and John Capgrave's Solace of Pilgrims also acknowledge their centrality in the European cultural imagination.
The introduction explains the dissertation's methodology and theoretical concerns. It then surveys familiar images of papal Rome and northern Italian bankers and merchants as they appear in literary and official texts. The first chapter focuses on the alliterative Morte Arthure's aligning of imperial Rome and the medieval northern Italian communes with the “Saracen” East and Africa. In the second chapter Lydgate's Fall of Princes is examined for its moralistic and highly critical assessment not only of ancient Roman history but also of the Anglophobic and untrustworthy Boccaccio. Finally, the third chapter shows how in the Solace of Pilgrims Capgrave celebrates Christian Rome's triumph over its earlier pagan identity but also scorns the current barbarity, weak faith and confabulating tendencies of contemporary Romans. The chapter concludes by considering the two different ideas of Rome present in Capgrave's pilgrimage manual and the Book of Margery Kempe.
The English writers analyzed here at once acknowledge the cultural, historical and economic importance of Rome, Florence, Genoa, Venice, Milan and their surrounding regions, but at the same time suggest that ultimately it is English spiritual piety, cultural unity and the steadfastness of English kings and princes that make England superior to Italy. Although England forms, with the Italian city-states, part of the communis patria or common fatherland of imperial and papal Rome, the constant strife and violence in Italy and the subversive traits of Italians in England lead English writers to look beyond and even to question that commonality.

Summary: Examines documentary evidence for the use of Rome's suburban cemeteries from the 6th-14th cs; and presents a catalogue of mural paintings added to the catacombs during this period. Argues that there are three distinct phases of use: as large extra-mural cemeteries (ca.200-first half, 6th c.); as pilgrimage sites for the veneration of tombs of saints (6th-early 8th cs.); and as underground chapels and hypogea associated with monasteries (second half, 8th c.-14th c.).

Robbins, Deborah King. A Case Study of Medieval Urban Process: Rome's Trastevere (1250-1450) (Italy). Ph. D Dissertation University of California, Berkeley. Advisor: Spiro Kostof. 1989. Summary: This dissertation focuses on the Roman district of Trastevere in the late Middle Ages (1250-1450). The structure of the dissertation is determined by the multiple themes of urban process--topographic, socio-economic, political, religious and architectural. Topographic and socio-economic conditions established in antiquity laid the foundation for Trastevere's medieval development. These include the administrative distinction of Trastevere resulting from its geographic location across the Tiber from the rest of Rome, its early connections with Rome's maritime trade, and the ancient region's street pattern. Trastevere's early medieval transformation was determined by the pathways of old and new streets, and the location of newly important sites and monuments. Continued political ambiguity and conflict result from the region's topographic isolation.
The urban port of Rome, Trastevere's most important economic institution, was located on Trastevere's river bank from the ninth century. This site created an undeniable economic link between Trastevere and Cistiberine Rome, as well as a unique and important Trasteverine neighborhood and market. Another urban center developed around the church of S. Maria in Trastevere, the region's largest basilica. As an urban center, parish church, and landowner, the church of S. Maria was influential in the urban fabric.
Trastevere's medieval residential fabric reveals social determinants. Three classes of houses defined the streets of Trastevere and ranged from the simplest dwelling to impressive palaces, suggesting a mixed social topography. Their organization was structured by family life, while entire neighborhoods responded to the dominance of a noble family compound. Both the public and private realms of the built environment were supervised by municipal building officials. The regulation of Rome's urban fabric, however limited in contrast with some medieval cities, was an important civic concern. The church was also involved in urban regulation in its role as landlord, maintaining the public domain against the threats of private intrusion.
Each of these historical determinants contributed to the urban process and transformed the urban fabric of medieval Trastevere. This analysis of urban process suggests possibilities for fresh interpretations of urban form in Rome and in cities everywhere.
