"The Revelation of Peter shows remarkable kinship in ideas with the Second Epistle of Peter. It also presents notable parallels to the Sibylline Oracles while its influence has been conjectured, almost with certainty, in the Acts of Perpetua and the visions narrated in the Acts of Thomas and the History of Barlaam and Josaphat. It certainly was one of the sources from which the writer of the Vision of Paul drew. And directly or indirectly it may be regarded as the parent of all the mediaeval visions of the other world."
