At sunset, on the second day, we arrived at Birsis, where there are a number of wells, and mutilated fragments of building, of which it would be impossible to make any satisfactory plan, without a great deal of previous excavation. Birsis occupies a very fertile plain, where there is usually an Arab encampment, and is distant about thirty-one miles from Bengazi, and seven from the city of Teuchira. It is five or six miles from the Cyrenaic range, and about a mile and a half from the sea. A little to the S.W. of Birsis, are other remains of building, which assume a more decided character, and appear to have formed part of a town. Several arched door-ways are still remaining, and some of the walls of the houses are standing, to the height of about ten or twelve feet from the present level. The spot on which they stand is now much overgrown with high grass and shrubs of various kinds, and the buildings have been occasionally added-to by the Arabs; so that it requires a good deal of attention to make out their original plans. We were cautioned by the natives, who saw us making our way through the high grass and bushes which encumber the ruins, to beware of the serpents, which they said were very numerous in the place; we, however, saw no more than two, one of a dark colour, about five feet in length, and another of smaller dimensions. The Arab name for this place is Mabny, and Mably (as we heard it pronounced by different persons residing on the spot); and appears to be a corruption of Napoli, or Neapolis, with no other change than might reasonably be expected from the peculiarities of Arab pronunciation[9]. Neapolis is, however, laid down by Ptolemy between the cities of Teuchira and Ptolemeta; and Mably (or Mabny) is seven or eight miles to the S.W. of the former of these places; so that it will not correspond in position with the city which its name appears to indicate. We may at the same time observe, that in the position assigned by Ptolemy to Neapolis we could perceive no remains which were indicative of a town; that we know of no town, described under another name, as occupying the site of Mably; and that the resemblance of that appellation to Nably, which would be the Arab pronunciation of Neapolis, is too close to be wholly overlooked.
