and the city of Elephantine, is divided into two parts and that it thus partakes of both the names, since one side will thus belong to Libya and the other to Asia; for the Nile from the Cataract onwards flows to the sea cutting Egypt through the midst; and as far as the city of Kercasoros the Nile flows in one single stream, but from this city onwards it is parted into three ways; and one, which is called the Pelusian mouth, turns towards the East; the second of the ways goes towards the West, and this is called the Canobic mouth; but that one of the ways which is straight runs thus⁠—when the river in its course downwards comes to the point of the Delta, then it cuts the Delta through the midst and so issues out to the sea. In this we have 261 a portion of the water of the river which is not the smallest nor the least famous, and it is called the Sebennytic mouth. There are also two other mouths which part off from the Sebennytic and go to the sea, and these are called, one the Saitic, the other the Mendesian mouth. The Bolbitinitic and Bucolic mouths, on the other hand, are not natural but made by digging 18.
