The passage from Antiquity to the Middle Ages has been largely studied in the light of the thesis of a gradual transformation, which is in contradiction of the previous assumption of an abrupt break due to war and general calamity. Perceiving War and the Military reassesses this historical period of transition by an investigation of the contemporary world of thought that examines the impact and significance of a permanently increasing contact with warfare and armed violence. Her studies confirm the assumption of a gradual shift, but they most of all show that the irrevocable end of the Roman Peace was a crucial factor in the late Roman world becoming gradually “medieval”.

Literary Territories introduces readers to a wide range of literature from 200-900 CE in which geography is a defining principle of literary art. From accounts of Holy Land pilgrimage, to Roman mapmaking, to the systematization of Ptolemy's scientific works, Literary Territories argues that forms of literature that were conceived and produced in very different environments and for different purposes in Late Antiquity nevertheless shared an aesthetic sensibility which treated the classical "inhabited world," the oikoumene, as a literary metaphor for the collection and organization of knowledge. This type of "cartographical thinking" stresses the world of knowledge that is encapsulated in the literary archive. The archival aesthetic coincided with an explosion of late antique travel and Christian pilgrimage which in itself suggests important unifying themes between visual and textual conceptions of space. Indeed, by the end of Late Antiquity the geographical mode appears in nearly every type of writing in multiple Christian languages (Greek, Latin, Syriac, and others). The diffusion of cartographical thinking throughout the real-world oikoumene, now the Christian Roman Empire, was a fundamental intellectual trajectory of Late Antiquity.

A sweeping intellectual history of the role of wealth in the church in the last days of the Roman Empire Jesus taught his followers that it is easier for a camel to go through the eye of a needle than for a rich man to enter heaven. Yet by the fall of Rome, the church was becoming rich beyond measure. Through the Eye of a Needle is a sweeping intellectual and social history of the vexing problem of wealth in Christianity in the waning days of the Roman Empire, written by the world's foremost scholar of late antiquity. Peter Brown examines the rise of the church through the lens of money and the challenges it posed to an institution that espoused the virtue of poverty and called avarice the root of all evil. Drawing on the writings of major Christian thinkers such as Augustine, Ambrose, and Jerome, Brown examines the controversies and changing attitudes toward money caused by the influx of new wealth into church coffers, and describes the spectacular acts of divestment by rich donors and their growing influence in an empire beset with crisis. He shows how the use of wealth for the care of the poor competed with older forms of philanthropy deeply rooted in the Roman world, and sheds light on the ordinary people who gave away their money in hopes of treasure in heaven. Through the Eye of a Needle challenges the widely held notion that Christianity's growing wealth sapped Rome of its ability to resist the barbarian invasions, and offers a fresh perspective on the social history of the church in late antiquity.
