Note 755 — Chapter XXIII · “THE NILE IS EGYPT”
Reading edition
The Nile is the second longest river in the world (Perthes, Taschen Atlas). The Egyptians believed that it sprang from four sources at the twelfth gate of the nether world, at a place described in ch. 146 of the Book of the Dead, and that it came to light at the two whirlpools of the first cataract.
