In recent years there has been so much research into extra-canonical gospel literature and, in particular, into the Coptic Gnostic library of Nag Hammadi that a completely new recasting of the seminal work, Neutestamentliche Apokryphen in Deutscher Ubersetzung (originally founded by Edgar Hennecke), seemed called for. This is the English translation of the revised edition of that work, published in two volumes. This is an essential collection of sources for every student of the New Testament and of the history and literature of ancient Christianity. Volume I covers the Gospels and related writings, including the various Gnostic Gospels and Infancy Gospels.
