Septuagint: Tobit (Sinaiticus Version)

The Book of Tobit is generally viewed as fiction by most scholars for a variety of reasons. One major reason it is viewed as fiction is the presence of Tobit's cousin Ahikar, in both versions of the book, who is the protagonist of the Words of Ahikar, a book set in the same era, which is also considered fiction. It is quite clear from the text of Tobit, that it is the same Ahikar, and not just someone with the same name, as Ahikar's betrayal by his nephew is mentioned, which is part of the early section of Ahikar. Nevertheless, both books, Tobit and Ahikar survive in various forms, meaning that they were edited multiple times before the versions that survive to the present were transcribed. The surviving copies of the Septuagint include two versions of the Book of Tobit, the more common form, found in the Codex Vaticanus, Codex Alexandrinus, and most other surviving copies of the Septuagint, and the less common version found in the Codex Sinaiticus.

The differences between the Vaticanus and Sinaiticus versions of Tobit are too extensive to treat the books as the same book, however, their story is essentially the same. The two books must have had a common source, however, the Sinaiticus's version is over 20% longer than the Vaticanus's version, and appears to be an older version of Tobit. One of the reasons that the Book of Tobit is interpreted as fiction, is the existence of historical errors and anachronisms found in the Vaticanus version, which includes the Babylonian king Nebuchadnezzar and the Persian king Ahasuerus jointly destroying Nineveh, the capital of the Assyrian Empire. Nineveh was sacked by Babylonian King Nabopolassar in 612 BC, along with Median and Persian allies, led by the Median King Cyaxares, who then integrated the city into his Median Empire. Nabopolassar's son Nebuchadnezzar, who assumed the throne in 605 BC, finally conquered the remnants of the Assyrian forces in Syria at the Battle of Carchemish that same year, however, he did not attack or destroy Nineveh. Meanwhile, the name Ahasuerus was the Aramaic name of Xerxes, the Persian king who ruled between 486 and 465 BC.
