The shorter Latin Apocalypse of Ezra has become fused with the Judahite Apocalypse of Ezra in most Catholic and Protestant translations, however, scholars divide the Catholic versions of 4ᵗʰ Esdras (Protestant 2ⁿᵈ Esdras) into three sections, with only the core twelve chapters that correspond to the Orthodox and Ethiopian versions of the book labeled as 4ᵗʰ Ezra. The opening two chapters, which are only found in the Catholic version, are labeled as 5ᵗʰ Ezra, while the last 2 chapters found in Catholic version, as well as fragments surviving in an ancient Greek translation, are labeled 6ᵗʰ Ezra. 5ᵗʰ Ezra and 6ᵗʰ Ezra appear to have originally been one document, which is commonly called the Latin Apocalypse of Ezra, although it was almost certainly not written in Latin.
In chapter 1 and 2 of the apocalypse, which is 5ᵗʰ Ezra, the author claimed to be Ezra the scribe, and gave his genealogy, which is found in the books of Ezra found in the Masoretic text and Septuagint, however, then claims he had been held captive in Media during the time of Artaxerxes. Chapter 3 and the beginning of chapter 4 of the apocalypse, the bulk of 6ᵗʰ Ezra, appears to be much older, and describe a world that the author of the longer apocalypse did not seem to understand. The prophecy itself was focused on fall of the Assyrian Empire, which did fall in 609 BC. The Assyrian Empire fell to a large alliance of its enemies, including the Medes, Scythians, and the rebelling Babylonians. The prophet, whoever it was, did not know this would happen, and did not mention the Medes or Scythians, and prophesied that after defeating the Assyrians, the conquerors would besiege Babylon, demonstrating the prophesy was made before Babylon revolted in 626 BC.
