(ii). Lake Mariout was much deeper then than now, and directly connected with the Nile. Consequently it was almost as important a water-way as the sea, and a lake harbour was an integral part of the plan. (iii). There was then through water-connection between the Mediterranean and the Red Sea. The ancient Egyptians had cut a canal from the Nile at Memphis down to the salt lakes that begin by the modern Ismailia. Thus Alexandria stood in the position of Port Said to-day; a maritime gateway to India and the remoter east. * * * * * The city was oblong, and filled up the strip between the Lake and the sea; she was laid out in rigidly straight lines. Her main street (the “Canopic”) still exists in part as the Rue Rosette. It ran almost due east and west—a bad direction because it was cut off from the cool north wind that is the real tutelary god of Alexandria, but, owing to the site, nothing else could be contrived. Westward it terminated in the sea; eastward it proceeded to Canopus (Aboukir). It was the natural highway along the limestone spur, and no doubt existed long before Alexander came. Crossing the Canopic Street, and following the line of the present Rue Nebi Daniel, was the second main artery, the street of the Soma. It started at the Lake Harbour and ran northward to the sea. Where it intersected the Canopic Street stood the Soma, or burial place of Alexander—close to the present Mosque. Parallel to these two streets ran others, dividing the city into blocks of an American regularity. It could not have been picturesque, but the Greeks did not desire picturesqueness. They liked to lay their towns out evenly—Rhodes and Halicarnassus had just been laid out on the same lines—and the only natural feature they cared to utilise was the sea. The blocks were labelled according to the letters of the Greek alphabet. Of the sea front magnificent use was to be made. Only one feature shall be mentioned here: the dyke Heptastadion (seven stades long) which was built to connect the island of Pharos and the mainland. It performed two functions; it enlarged the city area, and it broke the force of the currents and created a double harbour—the Great Harbour to the east and the Eunostos (“Safe Return”) to the west. In the Arab period the Heptastadion silted up and became the neck of land that leads to Ras-el-Tin.
