Only one book in the Hebrew Bible is generally classified as apocalyptic literature, and that is the book of Daniel. But that is not to say that Daniel is the only book that shows characteristics typical of apocalyptic literature. Certain motifs characteristic of apocalyptic eschatology can be found in the myths of ancient Mesopotamia. Motifs of cosmic warfare pervade mythic material, such as the battle between the high gods and the sea monsters. This divine warrior motif is also present in biblical apocalyptic literature.
Most of the scholars today —who are now in the majority—disagree.  They contend that it is much more likely that the Jewish community itself instigated the translation to serve their own liturgical and pedagogical needs. When scholars holding this position reinvestigate Ptolemy’s supposed interest in a Greek translation of Jewish Law, the evidence begins to evaporate.
