Of the commercial intercourse of Egypt with the regions adjoining it on the south, as well as with Arabia and India, we shall speak more fully in the sequel. The traffic with the countries of the Mediterranean comes less into prominence in the traditional account, partly, doubtless, because it belonged to the ordinary course of things, and there was not often occasion to make special mention of it. The Egyptian corn was conveyed to Italy by Alexandrian shipmasters, and in consequence of this there arose in Portus near Ostia a sanctuary modelled on the Alexandrian temple of Sarapis with a mariner’s guild;[231] but these transport-ships would hardly be concerned to any considerable extent in the sale of the wares going from Egypt to the West. This sale lay probably just as much, and perhaps more, in the hands of the Italian ship-owners and captains than of the Egyptian; at least there was already under the Lagids a considerable Italian settlement in Alexandria,[232] and the Egyptian merchants had not the same diffusion in the West as the Syrian.[233] The ordinances of Augustus, to be mentioned afterwards, which remodelled the commercial traffic on the Arabian and Indian Seas, found no application to the navigation of the Mediterranean; the government had no interest in favouring the Egyptian merchants more than the rest in its case. The traffic there remained, presumably, as it was. [Sidenote: Population.] Egypt was thus not merely occupied, in its portions capable of culture, with a dense agricultural population, but also as the numerous and in part very considerable hamlets and towns enable us to recognise, a manufacturing land, and hence accordingly by far the most populous province of the Roman empire. The old Egypt is alleged to have had a population of seven millions; under Vespasian there were counted in the official lists seven and a half millions of inhabitants liable to poll tax, to which fall to be added the Alexandrians and other Greeks exempted from poll tax, so that the population, apart from the slaves, is to be estimated at least at eight millions of persons. As the area capable of cultivation may be estimated at present at 10,500 English square miles, and for the Roman period at the most at 14,700, there dwelt at that time in Egypt on the average about 520 persons to the square mile. When we direct our glance upon the inhabitants of Egypt, the two nations inhabiting the country--the great mass of the Egyptians and the small minority of the Alexandrians--are circles thoroughly different,[234] although the contagious power of vice and the similarity of character belonging to all vice have instituted a bad fellowship of evil between the two.
