The corresponding border town on the Syrian side is represented by the picturesque and finely preserved ruins called Salahiya, the Ad-dalie or Dalie (Adalia) of Arabic times, two days below Deir, whose more ancient name is as yet unknown.
Between Salahiya and Deir, on an old canal, known in Arabic times as Said, leaving the Euphrates a little below Deir and rejoining it above Salahiya, stand the almost more picturesque ruins of the once important Arabic fortress of Rahba.
Below Salahiya the river-bed narrows and becomes more rocky.
A day's journey beyond Salahiya, on a bluff on the Mesopotamian side of the river, are the conspicuous ruins of el-`Irsi (Corsote?).
