Theodor Mommsen - The history of Rome

Carthage was rendered very strong both by the nature of its situation [8] . The line of the coast has been in the course of centuries so much changed that the former local relations are but imperfectly recognizable on the ancient site. The name of the city is preserved by Cape Cartagena - also called from the saint's tomb found there Ras Sidi bu Said - the eastern headland of the peninsula, projecting into the gulf with its highest point rising to 393 feet above the level of the sea. and by the art of its inhabitants, who had very often to depend on the protection of its walls. Into the broad gulf of Tunis, which is bounded on the west by Cape Farina and on the east by Cape Bon, there projects in a direction from west to east a promontory, which is encompassed on three sides by the sea and is connected with the mainland only towards the west. This promontory, at its narrowest part only about two miles broad and on the whole flat, again expands towards the gulf, and terminates there in the two heights of Jebel-Khawi and Sidi bu Said, between which extends the plain of El Mersa. On its southern portion which ends in the height of Sidi bu Said lay the city of Carthage. The pretty steep declivity of that height towards the gulf and its numerous rocks and shallows gave natural strength to the side of the city next to the gulf, and a simple circumvallation was sufficient there. On the wall along the west or landward side, on the other hand, where nature afforded no protection, every appliance within the power of the art of fortification in those times was expended. It consisted, as its recently discovered remains exactly tallying with the description of Polybius have shown, of an outer wall 6 1/2 feet thick and immense casemates attached to it behind, probably along its whole extent; these were separated from the outer wall by a covered way 6 feet broad, and had a depth of 14 feet, exclusive of the front and back walls, each of which was fully 3 feet broad [9] . The dimensions given by Beule (Fouilles a Carthage, 1861) are as follows in metres and in Greek feet (1=0.309 metre): Outer wall 2 metres = 6 1/2 feet. Corridor 1.9" = 6" Front wall of casemates 1" = 3 1/4" Casemate rooms 4.2" = 14" Back wall of casemates 1" = 3 1/4" Whole breadth of the walls 10.1 metres = 33 feet. Or, as Diodorus (p. 522) states it, 22 cubits (1 Greek cubit = 1 1/2 feet), while Livy (ap. Oros. iv. 22) and Appian (Pun. 95), who seem to have had before them another less accurate passage of Polybius, state the breadth of the walls at 30 feet. The triple wall of Appian - as to which a false idea has hitherto been diffused by Floras (i. 31) - denotes the outer wall, and the front and back walls of the casemates. That this coincidence is not accidental, and that we have here in reality the remains of the famed walls of Carthage before us, will be evident to every one: the objections of Davis (Carthage and her Remains, p. 370 et seq.) only show how little even the utmost zeal can adduce in opposition to the main results of Beule. Only we must maintain that all the ancient authorities give the statements of which we are now speaking with reference not to the citadel-wall, but to the city-wall on the landward side, of which the wall along the south side of the citadel-hill was an integral part (Oros. iv. 22). In accordance with this view, the excavations at the citadel-hill on the east, north, and west, have shown no traces of fortifications, whereas on the south side they have brought to light the very remains of this great wall. There is no reason for regarding these as the remains of a separate fortification of the citadel distinct from the city wall; it may be presumed that further excavations at a corresponding depth - the foundation of the city wall discovered at the Byrsa lies fifty-six feet beneath the present surface - will bring to light like, or at any rate analogous, foundations along the whole landward side, although it is probable that at the point where the walled suburb of Magalia rested on the main wall the fortification was either weaker from the first or was early neglected. The length of the wall as a whole cannot be stated with precision; but it must have been very considerable, for three hundred elephants were stabled there, and the stores for their fodder and perhaps other spaces also as well as the gates are to be taken into account. It is easy to conceive how the inner city, within the walls of which the Byrsa was included, should, especially by way of contrast to the suburb of Magalia which had its separate circumvallation, be sometimes itself called Byrsa (App. Pun. 117; Nepos, ap. Serv. Aen. i. 368). . This enormous wall, composed throughout of large hewn blocks, rose in two stories, exclusive of the battlements and the huge towers four stories high, to a height of 45 feet [10] . Such is the height given by Appian, l. c.; Diodorus gives the height, probably inclusive of the battlements, at 40 cubits or 60 feet. The remnant preserved is still from 13 to 16 feet (4-5 metres) high. , and furnished in the lower range of the casemates stables and provender-stores for 300 elephants, in the upper range stalls for horses, magazines, and barracks [11] . The rooms of a horse-shoe shape brought to light in excavation have a depth of 14, and a breadth of 11, Greek feet; the width of the entrances is not specified. Whether these dimensions and the proportions of the corridor suffice for our recognizing them as elephants' stalls, remains to be settled by a more accurate investigation. The partition-walls, which separate the apartments, have a thickness of 1.1 metre = 3 1/2 feet. . The citadel-hill, the Byrsa (Syriac, birtha = citadel), a comparatively considerable rock having a height of 188 feet and at its base a circumference of fully 2000 double paces [12] . Oros. iv. 22. Fully 2000 paces, or - as Polybius must have said - 16 stadia, are=about 3000 metres. The citadel-hill, on which the church of St. Louis now stands, measures at the top about 1400, half-way up about 2600, metres in circumference (Beule, p. 22); for the circumference at the base that estimate will very well suffice. , was joined to this wall at its southern end, just as the rock-wall of the Capitol was joined to the city-wall of Rome. Its summit bore the huge temple of the God of Healing, resting on a basement of sixty steps. The south side of the city was washed partly by the shallow lake of Tunes towards the south-west, which was separated almost wholly from the gulf by a narrow and low tongue of land running southwards from the Carthaginian peninsula [13] . It now bears the fort Goletta. , partly by the open gulf towards the south-east.

At this last spot was situated the double harbour of the city, a work of human hands; the outer or commercial harbour, a longish rectangle with the narrow end turned to the sea, from whose entrance, only 70 feet wide, broad quays stretched along the water on both sides, and the inner circular war-harbour, the Cothon [14] . That this Phoenician word signifies a basin excavated in a circular shape, is shown both by Diodorus (iii. 44), and by its being employed by the Greeks to denote a "cup." It thus suits only the inner harbour of Carthage, and in that sense it is used by Strabo (xvii. 2, 14, where it is strictly applied to the admiral's island) and Fest. Ep. v. cothones . 37. Appian (Pun. 127) is not quite accurate in describing the rectangular harbour in front of the Cothon as part of it. , with the island containing the admiral's house in the middle, which was approached through the outer harbour. Between the two passed the city wall, which turning eastward from the Byrsa excluded the tongue of land and the outer harbour, but included the war-harbour, so that the entrance to the latter must be conceived as capable of being closed like a gate. Not far from the war-harbour lay the marketplace, which was connected by three narrow streets with the citadel open on the side towards the town. To the north of, and beyond, the city proper, the pretty considerable space of the modern El Mersa, even at that time occupied in great part by villas and well-watered gardens, and then called Magalia, had a circumvallation of its own joining on to the city wall. On the opposite point of the peninsula, the Jebel-Khawi near the modern village of Ghamart, lay the necropolis. These three - the old city, the suburb, and the necropolis - together filled the whole breadth of the promontory on its side next the gulf, and were only accessible by the two highways leading to Utica and Tunes along that narrow tongue of land, which, although not closed by a wall, yet afforded a most advantageous position for the armies taking their stand under the protection of the capital with the view of protecting it in return.
