News just broke Tuesday in the New York Times on the appearance of an ancient papyrus that speaks about Jesus as possibly having a wife. The papyrus has been dated to the fourth century. Karen King who has presented the only known information about the fragment has pointed out that it may have been composed in the second century.
According to Christian Askeland, the majority of Coptologists (the fragment is written in Coptic) seem to think at this time that the document is a forgery (see also the comments to Christian's post).
See further information here, including comments from Simon Gathercole who is a specialist on apocryphal gospels.
A high resolution image and a translation of the document may be found in the NY Times article.
