This book aims to documentarily demonstrate the underlying theological meanings of the conjugal bed in some medieval and Renaissance images of the Annunciation to Mary. To justify with academic rigorhis iconographic interpretations of such furniture in these images, the author of the book analyzes an abundant corpus of texts in which, for more than a millennium, many medieval Fathers, theologians, and hymnographers of the Eastern and Western Churches explained with Mariological and Christological projection the textual metaphors thalamus Dei and other similar rhetorical figures alluding to marital coexistence.
