[Sidenote: Such preliminary sketches are necessary for clearness, and my readers must not be surprised if I follow the same system in the case of other towns.]
Such was the nature and motive of the first warlike expedition of the Romans beyond the shores of Italy; and this was the period at which it took place. I thought this expedition the most suitable starting-point for my whole narrative, and accordingly adopted it as a basis; though I have made a rapid survey of some anterior events, that in setting forth its causes no point should be left obscure. I thought it necessary, if we were to get an adequate and comprehensive view of their present supreme position, to trace clearly how and when the Romans, after the disaster which they sustained in the loss of their own city, began their upward career; and how and when, once more, after possessing themselves of Italy, they conceived the idea of attempting conquests external to it. This must account in future parts of my work for my taking, when treating of the most important states, a preliminary survey of their previous history. In doing so my object will be to secure such a vantage-ground as will enable us to see with clearness from what origin, at what period, and in what circumstances they severally started and arrived at their present position. This is exactly what I have just done with regard to the Romans.

Carthaginian movements in Spain, B.C. 241-218. 4. Illyrian war, B.C. 229-228. 5. Gallic war, B.C. 225-221. 6. Cleomenic war, B.C. 227-221.]
+13.+ It is time to have done with these explanations, and to come to my subject, after a brief and summary statement of the events of which my introductory books are to treat. Of these the first in order of time are those which befell the Romans and Carthaginians in their war for the possession of Sicily. Next comes the Libyan or Mercenary war; immediately following on which are the Carthaginian achievements in Spain, first under Hamilcar, and then under Hasdrubal. In the course of these events, again, occurred the first expedition of the Romans into Illyria and the Greek side of Europe; and, besides that, their struggles within Italy with the Celts. In Greece at the same time the war called after Cleomenes was in full action. With this war I design to conclude my prefatory sketch and my second book.
[Sidenote: The first Punic war deserves more detailed treatment, as furnishing a better basis for comparing Rome and Carthage than subsequent wars.]
