In this evocative essay on the cultural and social history of a unique and fragile city, Jonathan Porter examines Macau as an enduring but ever-changing threshold between East and West. Establishing Portugal and China as distinct cultural archetypes, Porter then examines the subsequent encounters of East and West in Macau from the sixteenth to the twentieth centuries. Avoiding the traditional linear chronological approach, Porter instead looks at a series of images from the city's history and culture, including its place in the geographical context of the South China coast; the architecture of Macau, which reflects the memories of its historical passages; the variety of people who crossed the threshold of Macau; the material culture of everyday life; and the spiritual topography resulting from the encounters of popular religious movements in Macau.
