O'er Egypt's land of memory floods are level, And they are thine, O Nile! and well thou knowest The soul-sustaining airs and blasts of evil, And fruits, and poisons spring where'er thou flowest.
Percy Bysshe Shelley, Geoffrey Matthews, Kelvin Everest (1989). “The Poems of Shelley: 1817-1819”, p.350, Pearson Education
