Ulai
Ulai is an ancient name for a river near Susa , the capital of the Elam Empire , in what is now Khuzestan Province in southwestern Iran . Today the Ulai is mostly identified with the Karche , although in the past the course of the Karche was subject to changes in the lower reaches.
The Ulai stream is mentioned several times in the Gilgamesh epic . On the Ulai at the end of the 12th century BC A battle between the Elamite king Hutelutuš-Inšušinak and the Babylonians under Nabû-kudurrī-uṣur I took place, in which the Elamites were defeated without the Babylonians being able to take the nearby Elamite residence of Susa. With the Assyrians the river is called Ulaa or Ulaia and among other things in the 7th century BC. In connection with a campaign by the Assyrian king Aššur-bāni-apli against the Elamites under Te-umman (Tempti-Khumma-In-Shushinak). The Ulai (Hebrew: אולי) is best known because it is mentioned twice as the location of a vision of the biblical prophet Daniel : Dan 8.2 EU Dan 8.16 EU . The river split into two arms around 30 km northeast of Susa, with the western arm running past the citadel of Susa and then westward through the Mesopotamian marshes and finally flowing into the Shatt al-Arab , while the eastern arm passed east of Susa and then followed today's lower reaches of the Karun . In Hellenistic times, the Ulai was known as Elaios and is possibly equated with the Choaspes. The western arm of the river (today's Karche) then shifted its course further westwards in post-Alexandrinian times, so that it now flows 2 km west of Susa, while the connection to the mouth of the Karun via the eastern river arm no longer exists today.
