Strabo Geography 16.4.8

[8] In the intervening space, a branch of the river Astaboras ¹ discharges itself. It has its source in a lake, and empties part of its waters [into the bay], but the larger portion it contributes to the Nile. Then follow six islands, called Latomiae, ² after these the Sabaïtic mouth, ³ as it is called, and in the inland parts a fortress built by Suchus. ⁴ Then a lake called Elaea, and the island of Strato; ⁵ next Saba ⁶ a port, and a hunting-ground for elephants of the same name. The country deep in the interior is called Tenessis. It is occupied by those Egyptians who took refuge from the government of Psammitichus. ⁷ They are surnamed Sembritae, ⁸ as being strangers. They are governed by a queen, to whom also Meroë, an island in the Nile near these places, is subject. Above this, at no great distance, is another island in the river, a settlement occupied by the same fugitives. From Meroë to this sea is a journey of fifteen days for an active person.

Near Meroë is the confluence of the Astaboras, ⁹ the Astapus, ¹⁰ and of the Astasobas with the Nile.
