1. Our accounts as to these events are not only imperfect but one- sided, for of course it was the version of the Carthaginian peace party which was adopted by the Roman annalists. Even, however, in our fragmentary and confused accounts (the most important are those of Fabius, in Polyb. iii. 8; Appian. Hisp. 4; and Diodorus, xxv. p. 567) the relations of the parties appear dearly enough. Of the vulgar gossip by which its opponents sought to blacken the "revolutionary combination" (—etaireia ton ponerotaton anthropon—) specimens may be had in Nepos (Ham. 3), to which it will be difficult perhaps to find a parallel.
2. The Barca family conclude the most important state treaties, and the ratification of the governing board is a formality (Pol. iii. 21). Rome enters her protest before them and before the senate (Pol. iii. 15). The position of the Barca family towards Carthage in many points resembles that of the Princes of Orange towards the States-General.
3. It was not till the middle ages that the route by Mont Cenis became a military road. The eastern passes, such as that over the Poenine Alps or the Great St. Bernard—which, moreover, was only converted into a military road by Caesar and Augustus—are, of course, in this case out of the question.
4. The much-discussed questions of topography, connected with this celebrated expedition, may be regarded as cleared up and substantially solved by the masterly investigations of Messrs. Wickham and Cramer. Respecting the chronological questions, which likewise present difficulties, a few remarks may be exceptionally allowed to have a place here.
When Hannibal reached the summit of the St. Bernard, "the peaks were already beginning to be thickly covered with snow" (Pol. iii. 54), snow lay on the route (Pol. iii. 55), perhaps for the most part snow not freshly fallen, but proceeding from the fall of avalanches. At the St. Bernard winter begins about Michaelmas, and the falling of snow in September; when the Englishmen already mentioned crossed the mountain at the end of August, they found almost no snow on their road, but the slopes on both sides were covered with it. Hannibal thus appears to have arrived at the pass in the beginning of September; which is quite compatible with the statement that he arrived there "when the winter was already approaching" —for —sunaptein ten tes pleiados dusin— (Pol. iii. 54) does not mean anything more than this, least of all, the day of the heliacal setting of the Pleiades (about 26th October); comp. Ideler, Chronol. i. 241.
If Hannibal reached Italy nine days later, and therefore about the middle of September, there is room for the events that occurred from that time up to the battle of the Trebia towards the end of December (—peri cheimerinas tropas—, Pol. iii. 72), and in particular for the transporting of the army destined for Africa from Lilybaeum to Placentia. This hypothesis further suits the statement that the day of departure was announced at an assembly of the army —upo ten earinen oran— (Pol. iii. 34), and therefore towards the end of March, and that the march lasted five (or, according to App. vii. 4, six) months. If Hannibal was thus at the St. Bernard in the beginning of September, he must have reached the Rhone at the beginning of August —for he spent thirty days in making his way from the Rhone thither —and in that case it is evident that Scipio, who embarked at the beginning of summer (Pol. iii. 41) and so at latest by the commencement of June, must have spent much time on the voyage or remained for a considerable period in singular inaction at Massilia.
CHAPTER V
The War under Hannibal to the Battle of Cannae
Hannibal and the Italian Celts
The appearance of the Carthaginian army on the Roman side of the Alps changed all at once the situation of affairs, and disconcerted the Roman plan of war. Of the two principal armies of the Romans, one had landed in Spain and was already engaged with the enemy there: it was no longer possible to recall it. The second, which was destined for Africa under the command of the consul Tiberius Sempronius, was fortunately still in Sicily: in this instance Roman delay for once proved useful. Of the two Carthaginian squadrons destined for Italy and Sicily, the first was dispersed by a storm, and some of its vessels were captured by the Syracusans near Messana; the second had endeavoured in vain to surprise Lilybaeum, and had thereafter been defeated in a naval engagement off that port. But the continuance of the enemy's squadrons in the Italian waters was so inconvenient, that the consul determined, before crossing to Africa, to occupy the small islands around Sicily, and to drive away the Carthaginian fleet operating against Italy. The summer passed away in the conquest of Melita, in the chase after the enemy's squadron, which he expected to find at the Lipari islands while it had made a descent near Vibo (Monteleone) and pillaged the Bruttian coast, and, lastly, in gaining information as to a suitable spot for landing on the coast of Africa; so that the army and fleet were still at Lilybaeum, when orders arrived from the senate that they should return with all possible speed for the defence of their homes.
