John J. Collins 
Apocalyptic Imagination 
An Introduction to Jewish Apocalyptic Literature

One of the most widely praised studies of Jewish apocalyptic literature ever written,  The Apocalyptic Imagination by John J. Collins has served for over thirty years as a helpful, relevant, comprehensive survey of the apocalyptic literary genre. After an initial overview of things apocalyptic, Collins proceeds to deal with individual apocalyptic texts — the early Enoch literature, the book of Daniel, the Dead Sea Scrolls, and others — concluding with an examination of apocalypticism in early Christianity. Collins has updated this third edition throughout to account for the recent profusion of studies germane to ancient Jewish apocalypticism, and he has also substantially revised and updated the bibliography.
