Pick, Bernhard. "Chapter Fourteen: Appendix. Remains of the Apocalypse of Peter." Paralipomena: Remains of Gospels and Sayings of Christ. Chicago: Open Court Publishing Company, 1908, 115-125.
An apocalypse of Peter is mentioned as a disputed work by the Muratorian Fragment and Clement of Alexandria (Pick 1908, 115). The work was subsequently identified as known but spurious in one way or another. It was not considered authoritative (Pick 1908, 116). A fragment was discovered, representing possibly about half of the work, in 1892 (Pick 1908, 117).
Pick provides an English version of the text (Pick 1908, 118ff). The descriptions of punishment are rather harsher and more detailed than those we find in the canonical Scriptures. They are also largely tied to behavior rather than belief on Christ.
