A detailed historical survey examines the interplay between civic government and ecclesiastical institutions in medieval London, opening with municipal records, charters, wards, and guilds before turning to religious life, liturgy, calendars, rites, pilgrimage, sanctuary, miracle plays, burial customs, and popular superstitions. A substantial section profiles monastic and charitable foundations—priories, hospitals, friaries, nunneries, fraternities—and their architecture, endowments, and daily functions. Appendices compile ward lists, parishes, patronages, festivals, and documentary excerpts, while numerous contemporary illustrations and plans accompany analytical narrative and documentary extracts.
