Such advantages of situation could not well have been overlooked by the ancients; and there is little doubt that this position was originally one of importance. It appears so well calculated, both by nature and art, for the establishment of a boundary line, that we have little hesitation in supposing the remains above mentioned to have at some period defended the limits of the states of Cyrene and Carthage; and it is accordingly here that we should feel most inclined to fix the site of the Castle of Euphrantes. The distance of this fort from Zaffràn, considered as Aspis, does indeed seem too great for the literal meaning of Strabo’s term συνεχης: but then the circumstance of its uniting a strong boundary line with a very conspicuous position, seems to make this place so very eligible a site for the castle in question, that we cannot refrain from pointing it out to our readers as the spot of all others which we could most wish should prove to be really such. We know the πυργος Ευφραντας to have been a boundary tower, since it is expressly said by Strabo to have been the limits of Carthage and Cyrene under the Ptolemies; so far therefore the resemblance between this fort and that of Strabo appears to be sufficiently complete. Again, amongst all the fortresses with which the Syrtis is filled, two only are mentioned in ancient history _by name_, those of Euphrantas and Automala; and it would seem probable, from this circumstance (at least it appears so to us), that these castles should have been distinguished from others by conspicuous positions. Of all the positions occupied by forts between Zaffràn and the point to which we are arrived, there is no one which can be materially distinguished from another but that of Bengerwàd, which we have just been describing; and this is so remarkably conspicuous a position, from the height of the eminence and its almost insulated situation on the beach, that it must have been at all times an object of importance from the sea, and could not fail to have been noticed by Strabo in his passage along this part of the coast. It is probable that the position of the Philænean Altars was not sufficiently well calculated by nature for a boundary; and that this circumstance, rather than the desire of increasing his territory in so unprofitable a district, induced one of the Ptolemies to remove the line of separation further westward to the castle of Euphrantas. In passing along the coast, in a westerly direction, from the sandy tract where the monuments of the Philæni[2] might be looked for, had they still been in existence, the most eligible situation which would present itself for a boundary post is certainly that of Bengerwàd; and this, as we have stated, is so extremely well calculated for such a purpose, that we can scarcely suppose it could have been overlooked by the king of Egypt when he fixed the new limits of his dominions.
