Summary of Targum Ruth
Date: 200-600 C.E.
Description: The Aramaic Targums (interpretation) of the Megillot (Ruth, Song of Songs, Lamentations, Ecclesiastes, Esther) are often treated by scholars as a single unit, as they lacked a fix place in traditional liturgy and were not associated with other Targum families such as Onkelos or Pseudo-Jonathan.
