Introduction

The roof bosses of Norwich Cathedral are among the great glories of medieval art. Over a thousand of these carved and brightly-painted keystones were placed high in the stone vaulting between 1315 and 1500. Hard for human eyes to see for 500 years, ‘visible only to the angels’, the carvings tell stories from the Old and New Testaments, and bring vividly to life key beliefs and narratives of the Middle Ages.
