The use of eschatological lists within the Targumim of the Megilloth

Several of the Targumim of the Megilloth contain lists (songs, famines, kings, etc.) that culminate in the future Messianic age. For example, Tg. Song opens with the list of Ten Songs and Tg. Ruth opens with the list of Ten Famines. Such lists are well known from other midrashic texts and this article will consider how and why these lists are used in the Targumim of the Megilloth and will propose that these additions are not merely the result of an opportunity presented by the Hebrew text but are being used specifically to further the overarching exegetical agenda of the Targum in question.
