What we must here understand by the flux and reflux of the sea, is not (we should imagine) the usual action of the tides, which is very trifling in the Mediterranean, compared with that which is observable in other seas; but the inset occasioned by violent winds blowing for any long continuance on shore, and the subsequent reaction of the sea in regaining its original level. As northerly winds are very prevalent, and very strong on this coast, which fronts the widest part of the Mediterranean, they might no doubt occasion the accumulation of soil alluded to in this passage of Strabo; and we certainly find that a great part of the coast is so exceedingly shallow as to make the landing very hazardous and difficult. It is probable, also, that this accumulation of soil has raised the level of the low lands in the Greater and Lesser Syrtes much above what it formerly was, and that both these regions were once covered with water to a greater depth than at present. We have already observed that the sea appears to have made great advances on the whole line of coast of Northern Africa; and this fact seems to be proved from the circumstance of our finding the remains of ancient towns, along its shores, at present under water to a considerable extent. We may now pass in boats over the ruins of the northern part of Alexandria, (as many travellers of our time can testify); and remains of the city of Carthage, “for the space of three furlongs in length, and half a furlong, or more, in breadth,” are well known (on the authority of Shaw[20]) to be at the present day “entirely under water.” In the intermediate space, we may instance the maritime towns of the Cyrenaica, where the sea has made considerable advances; those parts of the Greater Syrtis which are not exposed to the accumulation of sand, and the town of modern Tripoly, the northern part of which (as we have already stated in the words of Leo Africanus) appears to have been in his time under water. This rise in the level of the Mediterranean could scarcely fail to have occasioned an overflow in the low grounds of the Syrtie, to a much greater extent than formerly, if it had not been accompanied by, at least, a proportionate accumulation of soil: but it will rather appear that in these regions the land may be said to have advanced upon the sea; since we find their ancient ports now filled up with sand, their lakes to have taken the character of marshes, and their quicksands (if ever they had any) to have become solid and firm[21]. To these remarks we may add the observations of Major Rennell, on the actual and former state of the Lake Tritonis and the Lesser Syrtis, which we will give in the author’s own words.
