Barabbas by Par Lagerkvist. Picks up immediately after Barabbas’ release and follows him through despair and self-doubt as he wanders around wondering why he was allowed to live instead of the other guy. He does some research on Jesus until the Christians find out who he is. Short and bleak and pretty awesome.
I seem to remember Harry Mathews’s story “County Cooking from Central France” having a last supper subtext. I had to look up the subtitle to get it right: “Roast Boned Rolled Stuffed Shoulder of Lamb (Farce Double).
Reynolds Price did two translations, one of Mark and one of John, and also wrote his own apocryphal gospel, “An Honest Account of a Memorable Life.” I took a class with him last semester where we read the translations and then wrote our own gospels, but we didn’t actually read his—I think it hews pretty closely to the canonical gospels in its content, with a different sort of execution. But yeah, I ended up getting to write an 11,000-word apocryphal gospel, which was a pretty wild experience. For credit.
