The Roman History · Amm. 22.16.9

The shore is shifty and dangerous; and as in former times it exposed sailors to many dangers, Cleopatra erected a lofty tower in the harbour, which was named Pharos, from the spot on which it was built, and which afforded light to vessels by night when coming from the Levant or the Libyan sea along the plain and level coast, without any signs of mountains or towns or eminences to direct them, they were previously often wrecked by striking into the soft and adhesive sand.
