The Book of Tobit.  This is a narrative of a certain pious Naphtalite, Tobit by name, who has a son Tobias.  The father loses his eyesight; the son, dispatched to obtain payment of a debt to Tages in Media (which does not seem at the time to have been built), is led on by an angel to Ecbatana, where he makes a romantic marriage with a widow, who still remained a virgin, though she had been married to seven husbands, all of whom had been killed by Asmodeus, the evil spirit, on their marriage day.  Tobias, however, is encouraged by the angel to become the eighth husband of the virgin-widow, and escapes death by burning the inner parts of a fish, the smoke of which puts the evil spirit to flight.  Then he cures his father's blindness by anointing the darkened eyes with the gall of the fish which had already proved so useful.  Tobit is manifestly a tale, and not a serious narrative.  The most probable date of the publication is about 350 B.C., or from 250 to 200 B.C.
