The Gospel of Judas, originally stolen from Egypt, is now to be published by National Geographic. It's story, as summarized in this Christian Science Monitor article, is quite fascinating.
When the Gospel of Judas first surfaced in Geneva in 1983, scholars wondered if the mysterious text could trigger a reappraisal of history's most infamous traitor.
They never found out, however, because they couldn't afford the $3 million price tag on this second-century gnostic tale. Instead, the fragile pages vanished into private hands and set off on a 23-year, intercontinental journey through fist-pounding negotiations and even periods, reportedly, stuffed inside a Greek beauty's purse.
