"A Book of Cornwall" by S. Baring-Gould is a historical account written in the late 19th century. The book explores the rich historical and cultural heritage of Cornwall, focusing on its saints, churches, folklore, and notable localities, interweaving legends and actual historical events. The title suggests an in-depth examination of Cornish identity through its historical figures and customs. At the start of the book, the author introduces the fascinating topic of Cornish saints, describing multiple classes of saints who played crucial roles in the early history of Cornwall. Notably, the narrative hints at the relationships between saints, local geography, and how these figures contributed to the establishment of ecclesiastical and tribal systems. Baring-Gould discusses how these saints impacted Cornish culture and religion, suggesting they should be given more historical recognition rather than being viewed as trivial or obscure. The opening chapter sets the stage for a deeper dive into the complex interplay between religion and the development of Cornwall as a historical region. (This is an automatically generated summary.)
