TIGRIS . Only in RVm [Note: Revised Version margin.] of Genesis 2:14 and Daniel 10:4 , where both AV [Note: Authorized Version.] and RV [Note: Revised Version.] have Hiddekel (wh. see). The Tigris rises a little S. of Lake Göljik and flows southward to Diarbekr. After passing Diarbekr it receives the eastern Tigris (which rises in the Niphates mountains) at Osman Kleui. Then it flows through narrow gorges into the plateau of Mesopotamia, where it receives from the east the Greater and Lesser Zab, the Adhem or Radanu, and the Diyaleh or Tornadotus. On the E. bank, opposite Mosui, were Nineveh and Calah, a little N. of the junction of the Tigris and Greater Zab; and on the W. bank, N. of the Lesser Zab, was Assur (now Kalah Sherghat), the primitive capital of Assyria. The Tigris is about 1150 miles in length, and rises rapidly in March and April owing to the melting of the snows, falling again after the middle of May. Cf. also Eden [Garden of].
