The Orontes or Asi River

The Orontes or Asi (Arabic: العاصي‎, ‘Āṣī; Turkish: Asi) is a northward flowing river starting in Lebanon and flowing through Syria and Turkey before entering the Mediterranean Sea.

It was anciently the chief river of the Levant, also called Draco, Typhon and Axius. 

The last was a native form, from whose revival, or continuous employment in native speech, has preceded the modern name ‘Āṣī ("rebel"), 

because the river flows from the south to the north unlike the rest of the rivers in the region.
