Art and the Christian Apocrypha [PDF ebook] 

The Christian canon of scripture, known as the New Testament, excluded many of the Church»s traditional stories about its origins. Although not in the Bible, these popular stories have had a powerful influence on the Church»s traditions and theology, and a particularly marked effect on visual representations of Christian belief. This book provides a lucid introduction to the relationship between the apocryphal texts and the paintings, mosaics, and sculpture in which they are frequently paralleled, and which have been so significant in transmitting these non-Biblical stories to generations of churchgoers.
