This book weaves a web with strands that connect a favorite saint, an American revolution in stained glass design, a west-coast cultural renaissance, and a now obscure Swedish scientist and theologian. With beautiful photographs and prose, it brings to life the art and science of art conservation as dedicated people of various talents and interests struggle to preserve a cherished part of America's cultural heritage. --------------- Just as Porter cut glass and shaped lead when he first created his legendary stained glass, Douglas Stinson and Ariana Makau have fashioned and formed an artistic story of its restoration more than a century later. Revealing the modern techniques of restitution craftsmanship against the backdrop of significant San Francisco history, this book is its own work of art." James Lawrence, Assistant Professor of Spirituality, Graduate Theological Union and Dean of the Swedenborgian House of Studies.
