2 Enoch

Pseudonymously attributed to the patriarch Enoch; actual author and date are genuinely disputed, with proposals ranging from a Jewish text of the 1st century AD to a much later Byzantine-era or even medieval Slavonic composition -- the discovery of Coptic fragments has strengthened the case for an ancient origin. Survives complete only in Old Church Slavonic; recounts Enoch's ascent through the heavens and the cosmological and ethical teaching given to him.
