On the Greek mainland facing the Cyclades Islands and the Aegean Sea the Sunium promontory stands out from the Attic land. When you have rounded the promontory you see a harbor and a temple to Athena of Sunium on the peak of the promontory. Farther on is Laurium, where once the Athenians had silver mines, and a small uninhabited island called the Island of Patroclus. For a fortification was built on it and a palisade constructed by Patroclus, who was admiral in command of the Egyptian men-of-war sent by Ptolemy, son of Ptolemy, son of Lagus, to help the Athenians, when Antigonus, son of Demetrius, was ravaging their country, which he had invaded with an army, and at the same time was blockading them by sea with a fleet.1
