The western mouth does not afford an easy entrance, but it does not require the same degree of caution as the other. It forms also another port, which has the name of Eunostus, or Happy Return: it lies in front of the artificial and close harbour. That which has its entrance at the above-mentioned tower of Pharos is the great harbour. These (two) lie contiguous in the recess called Heptastadium, and are separated from it by a mound. This mound forms a bridge from the continent to the island, and extends along its western side, leaving two passages only through it to the harbour of Eunostus, which are bridged over. But this work served not only as a bridge, but as an aqueduct also, when the island was inhabited. Divus Cæsar devastated the island, in his war against the people of Alexandreia, when they espoused the party of the kings. A few sailors live near the tower.
The great harbour, in addition to its being well enclosed by the mound and by nature, is of sufficient depth near the shore to allow the largest vessel to anchor near the stairs. It is also divided into several ports.
The former kings of Egypt, satisfied with what they possessed, and not desirous of foreign commerce, entertained a dislike to all mariners, especially the Greeks (who, on account of the poverty of their own country, ravaged and coveted the property of other nations), and stationed a guard here, who had orders to keep off all persons who approached. To the guard was assigned as a place of residence the spot called Rhacotis, which is now a part of the city of Alexandreia, situated above the arsenal. At that time, however, it was a village. The country about the village was given up to herdsmen, who were also able (from their numbers) to prevent strangers from entering the country.
When Alexander arrived, and perceived the advantages of the situation, he determined to build the city on the (natural) harbour. The prosperity of the place, which ensued, was intimated, it is said, by a presage which occurred while the plan of the city was tracing. The architects were engaged in marking out the line of the wall with chalk, and had consumed it all, when the king arrived; upon which the dispensers of flour supplied the workmen with a part of the flour, which was provided for their own use; and this substance was used in tracing the greater part of the divisions of the streets. This, they said, was a good omen for the city.
7. The advantages of the city are of various kinds. The site is washed by two seas; on the north, by what is called the Egyptian Sea, and on the south, by the sea of the lake Mareia, which is also called Mareotis. This lake is filled by many canals from the Nile, both by those above and those at the sides, through which a greater quantity of merchandise is imported than by those communicating with the sea. Hence the harbour on the lake is richer than the maritime harbour. The exports by sea from Alexandreia exceed the imports. This any person may ascertain, either at Alexandreia or Dicæarchia, by watching the arrival and departure of the merchant vessels, and observing how much heavier or lighter their cargoes are when they depart or when they return.
In addition to the wealth derived from merchandise landed at the harbours on each side, on the sea and on the lake, its fine air is worthy of remark: this results from the city being on two sides surrounded by water, and from the favourable effects of the rise of the Nile. For other cities, situated near lakes, have, during the heats of summer, a heavy and suffocating atmosphere, and lakes at their margins become swampy by the evaporation occasioned by the sun’s heat. When a large quantity of moisture is exhaled from swamps, a noxious vapour rises, and is the cause of pestilential disorders. But at Alexandreia, at the beginning of summer, the Nile, being full, fills the lake also, and leaves no marshy matter which is likely to occasion malignant exhalations. At the same period, the Etesian winds blow from the north, over a large expanse of sea, and the Alexandrines in consequence pass their summer very pleasantly.
8. The shape of the site of the city is that of a chlamys or military cloak. The sides, which determine the length, are surrounded by water, and are about thirty stadia in extent; but the isthmuses, which determine the breadth of the sides, are each of seven or eight stadia, bounded on one side by the sea, and on the other by the lake. The whole city is intersected by roads for the passage of horsemen and chariots. Two of these are very broad, exceeding a plethrum in breadth, and cut one another at right angles. It contains also very beautiful public grounds and royal palaces, which occupy a fourth or even a third part of its whole extent. For as each of the kings was desirous of adding some embellishment to the places dedicated to the public use, so, besides the buildings already existing, each of them erected a building at his own expense; hence the expression of the poet may be here applied,
“one after the other springs.”[807]
All the buildings are connected with one another and with the harbour, and those also which are beyond it.
