The end of the ancient world was long regarded by historians as a time of decadence, decline, and fall. In his career-long engagement with this era, the widely acclaimed and pathbreaking historian Peter Brown has shown, however, that the "neglected half-millennium" now known as late antiquity was crucial to the development of modern Europe and the Middle East. In Journeys of the Mind, Brown recounts his life and work, describing his efforts to recapture the spirit of an age. As he and other scholars opened up the history of the classical world in its last centuries to the wider world of Eurasia and northern Africa, they discovered previously overlooked areas of religious and cultural creativity as well as foundational institution-building.

Documenting both his own intellectual development and the emergence of a new influential field of study, Brown describes his childhood and education in Ireland, his university and academic training in England, and his extensive travels. He discusses fruitful interactions with the work of scholars and colleagues and offers fascinating snapshots of such far-flung places as colonial Sudan, midcentury Oxford, and prerevolutionary Iran. With Journeys of the Mind, Brown offers an essential account of the "grand endeavor" to reimagine a decisive historical moment.
