The forces that led her to world-conquest were twofold, inner and outer. The inner one was the summer campaign habit, formed during several centuries; and the fact that she could form no conception of life that did not include it: the impulse to material expansion was deep in her soul, and ineradicable. She might have followed it, perhaps, north and westward; finished with Spain; gone up into Gaul (though in Gaul she might have found, even at that time, possibly, an unmanageable strength); she might even have carried her own ultimite salvation up into Germany. But we have seen Darius flow victorious eastward towards India, but unsuccessful when he tried the passes of the west; and Alexander follow him in the same path, and not turn westward at all. So you may say an eastward habit had been formed, and inner-channels were worn for conquest in that direction, but none in the other. Besides,—and this was the outer of the two forces,—the East was crying out to Rome. There were pirates on the other side of the Adriatic; and for the safety of her own eastern littoral she had been dealing with them, as with Spain, during and before the terrible Hannibalic time. To sit securely at home she must hold the Illyrian coast: and, she thought, or events proved it to her, to hold that coast safely, she must go conquering inland. Then again Egypt had courted her alliance, for regions. The Ptolemy of the time was a boy; and Philip of Macedon ind Antiochus of Syria had hatched a plan to carve up his juicy realm for their own most delectable feasting. It was the very year after peace—to call it that—had been forced on prostrate Carthage; and you might think an exhausted Rome would have welcomed
