The Name of Aruthia in Libya and Iberia

They say that nowhere, either in the parts of Libya or Iberia, is the name of Aruthia to be found. Men state that salt is obtained by digging at a depth of eighteen feet. In appearance white and not solid, but resembling the most sticky gum. When brought into the sun it hardens and becomes like Perian marble. The Phoenicians who inhabit the city called Gades when they sail outside the pillars of Heracles under an easterly wind for four days arrive at certain desolate places full of rushes and seaweed.
