It is much shorter, also much lower, lying mainly

below the surface of the sea in the form of reefs, but without it there would have been no harbours (and consequently no Alexandria), because it breaks the force of the waves. Starting at Agame, it continues as a series of rocks across the entrance of the modern harbour. Then it re-emerges to form the promontory of Ras el Tin, disappears into a second series of rocks that close the entrance of the Eastern Harbour, and makes its final appearance as the promontory of Silsileh, after which it rejoins the big spur.

Such is the scene where the following actions and meditations take place; that limestone ridge, with alluvial country on one side of it and harbours on the other, jutting from the desert, pointing towards the Nile; a scene unique in Egypt, nor have the Alexandrians ever been truly Egyptian. Here Africans, Greeks and Jews combined to make a city; here a thousand years later the Arabs set faintly but durably the impress of the Orient; here after secular decay rose another city, still visible, where I worked or appeared to work during a recent war. Pharos, the vast and heroic lighthouse that dominated the first city—under Pharos I have grouped a few antique events; to modern events and to personal impressions I have given the name of Pharillon, the obscure successor of Pharos, which clung for a time to the low rock of Silsileh and then slid unobserved into the Mediterranean.
