Richard Bauckham is one of the finest New Testament scholars alive today. His book “The Fate of the Dead” includes studies which focus on personal eschatology in Jewish and Christian Apocalypses. From Amazon description, “As well as better-known apocalypses, much attention is given to those neglected apocalypses which portray human destiny after death in detail, such as the "Apocalypse of Peter," the "Apocalypse of the Seven Heavens," the later apocalypses of Ezra, and the four apocalypses of the Virgin Mary. Relationships with Greco-Roman eschatology are explored, and several chapters show how specific New Testament texts are illuminated by close knowledge of this tradition of ideas and images of the hereafter.”
