This book aims to documentarily demonstrate the underlying theological meanings of the conjugal bed in some medieval and Renaissance imagesof the Annunciation to Mary. To justify with academic rigor hisiconographic interpretations of such furniture in these images, theauthor of the book analyzes an abundant corpus of texts in which, formore than a millennium, many medieval Fathers, theologians, andhymnographers of the Eastern and Western Churches explained withMariological and Christological projection the textual metaphorsthalamus Dei and other similar rhetorical figures alluding to maritalcoexistence. After an Introduction in which the iconographic problemraised by this bed in such images is highlighted, the book presentsfour chapters. The first exposes the exegeses given by the Fathers ofthe Greek-Eastern Churches on the reference metaphors. The seconddevelops similar explanations by the Fathers and theologians of theLatin West. The third chapter documents a wide range of fragments ofmedieval Latin liturgical hymns that lyrically deal with the metaphors above. The fourth chapter consists of the iconographical analysis oftwenty-five paintings of the Annunciation from the 14th and 15thcenturies, whose scene includes a conjugal bed. Based on thismillenary exegetical tradition, the author of the book criticizes some wrong or unjustified interpretations that several art historians have given of this bed in images of the Annunciation.
