Church dedications are as widely used as they are little studied, yet their histories are often obscure and complicated. Frequently forgotten after the Reformation, they were revived on the eighteenth and nineteenth centuries with many guesses and mistakes, resulting in numerous alterations. Church history cannot safely be based on the dedication in use today. Part One of the book surveys their history in England from roman ties to the present day. Part Two is detailed list of all 800 ancient parish churches and religious houses in Cornwall and Devon. It shows when their dedications first occur, the changes and misunderstandings that have happened, and the dates of parish feast days. Cornwall is a country of Celtic church dedication, whilst Devon's resemble this of the rest of England, so the book will be helpful in understanding dedications in both traditions.
