on the coast of Lucania.[14] The enterprise of their navigators had built up for the Phoenician cities and their great off-shoot Carthage, a sea-power which enabled them to gain the practical sovereignty of the sea to the west of Sardinia and Sicily. The control of these waters was the object of prolonged and memorable struggles, for on it--as the result showed--depended the empire of the world. From very remote times the consolidation and expansion, from within outwards, of great continental states have had serious consequences for mankind when they were accompanied by the acquisition of a coast-line and the absorption of a maritime population. We shall find that the process loses none of its importance in recent years. 'The ancient empires,' says the historian of Greece, Ernst Curtius, 'as long as no foreign elements had intruded into them, had an invincible horror of the water.' When the condition, which Curtius notices in parenthesis, arose, the 'horror' disappeared. There is something highly significant in the uniformity of the efforts of Assyria, Egypt, Babylon, and Persia to get possession of the maritime resources of Phoenicia. Our own immediate posterity will, perhaps, have to reckon with the results of similar efforts in our own day. It is this which gives a living interest to even the very ancient history of sea-power, and makes the study of it of great practical importance to us now. We shall see, as we go on, how the phenomena connected with it reappear with striking regularity in successive periods. Looked at in this light, the great conflicts of former ages are full of useful, indeed necessary, instruction. [Footnote 14: Mommsen, _Hist._Rome_, English trans., i. p. 153.]
