Apocalypse of Zephaniah

The Apocalypse of Zephaniah (or Apocalypse of Sophonias) is an ancient pseudepigraphic text (one whose claimed authorship is unfounded) attributed to the Biblical Zephaniah and so associated with the Old Testament, but not regarded as scripture by Jews or any Christian group. It was rediscovered and published at the end of 19th century. The canonical Book of Zephaniah has much mystical and apocalyptic imagery, and this apocalyptic-style text deals with a similar subject.

The existence of the Apocalypse of Zephaniah was known from ancient texts (for example the Stichometry of Nicephorus) but it was considered lost. In 1881 two fragmentary manuscripts, probably coming from the White Monastery in Egypt, were bought by the Bibliothèque Nationale of Paris and first published by U. Bouriant in 1885. These fragments, together with others later bought by the Staatliche Museum of Berlin, were published in 1899 by Steindorff who recognized in them fragments of the Apocalypse of Zephaniah, of the Apocalypse of Elijah and of another text he called The Anonymous Apocalypse. Schürer in 1899 showed that the Anonymous Apocalypse is most probably part of the Apocalypse of Zephaniah, but there is not unanimous consensus among scholars. The two manuscripts are written in Coptic dialects: the older (early fourth century CE) in Akhmimic, the other (early fifth century CE) in Sahidic and very limited in extension. The original text was probably written in Greek.
