Tobit is considered an apocrypha book, (hidden book), though it is canonized within the Catholic church. It tells the story of Tobit, an Israelite living in Nineveh after the deportation of Jews to Assyria in 721 B.C. Most of it is centered around his son, Tobias and the Archangel Raphael, who is disguised as a man. It is believed to have been quoted by the Prophet Amos, and also the The Book of Moses and The Law of Moses, indicating its authenticity and authority.
Books can be attributed to "Anonymous" for several reasons:
* They are officially published under that name * They are traditional stories not attributed to a specific author * They are religious texts not generally attributed to a specific author
Books whose authorship is merely uncertain should be attributed to Unknown.
Teaching story of a man named Tobit who is taken captive to Ninevah, rose to prominence, became wealthy, then lost all including his eyesight. Remembering he has some money in Media, he sends his son Tobias to retrieve it. Tobias is accompanied by the angel Raphael in disguise, and they catch a great fish.
At the same time a woman in Medea named Sarah has had her seventh husband killed by a demon on their honeymoon and prays to die. But Raphael tells Tobias to marry her, and they use parts of the fish to kill the demon and restore Tobit eyesight.
This is written to teach the Jews how to act toward God in the midst of tragedy. It contains historical and geographical errors making it historically impossible.
