These I designed to make the starting-point of what may almost be called a new work, partly because of the greatness and surprising nature of the events themselves, but chiefly because, in the case of most of them, I was not only an eye-witness, but in some cases one of the actors, and in others the chief director. [Sidenote: A new departure; the breaking-up of the arrangement made after the fall of Macedonia. Wars of Carthage against Massinissa; and of Rome against the Celtiberians, B.C. 155-150; and against Carthage (3d Punic war, B.C. 149-146).] +5.+ The events I refer to are the wars of Rome against the Celtiberians and Vaccaei; those of Carthage against Massinissa, king of Libya; and those of Attalus and Prusias in Asia. Then also Ariarathes, King of Cappadocia, having been ejected from his throne by Orophernes through the agency of King Demetrius, recovered his ancestral power by the help of Attalus; while Demetrius, son of Seleucus, after twelve years' possession of the throne of Syria, was deprived of it, and of his life at the same time, by a combination of the other kings against him. Then it was, too, that the Romans restored to their country those Greeks who had been charged with guilt in the matter of the war with Perseus, after formally acquitting them of the crimes alleged against them. Not long afterwards the same people turned their hands against Carthage: at first with the intention of forcing its removal to some other spot, but finally, for reasons to be afterwards stated, with the resolution of utterly destroying it. Contemporaneous with this came the renunciation by the Macedonians of their friendship to Rome, and by the Lacedaemonians of their membership of the Achaean league, to which the disaster that befell all Greece alike owed its beginning and end. This is my purpose: but its fulfilment must depend upon whether Fortune protracts my life to the necessary length. I am persuaded, however, that, even if the common human destiny does overtake me, this theme will not be allowed to lie idle for want of competent men to handle it; for there are many besides myself who will readily undertake its completion. But having given the heads of the most remarkable events, with the object of enabling the reader to grasp the general scope of my history as well as the arrangement of its several parts, I must now, remembering my original plan, go back to the point at which my history starts.
