The sight of that small group, hidden among the green foliage, was as brilliant as it was surprising. One of the officers, clearly the highest in rank, summoned us to come nearer, and asked the soldiers for an explanation. Standing smartly at attention, they gave it, as a school-child might haltingly recite a lesson learned by heart. The officer whom I thought it convenient to call "Captain" looked searchingly at me and then began:They made no allowance for the fact that they themselves had relieved all railway officials of their functions until later notification. The signalman was made a prisoner, but released subsequently.The evolution of Greek tragic poetry bears witness to the same transformation of taste. On comparing Sophocles with Aeschylus, we are struck by a change of tone analogous to that which distinguishes Thucydides from Herodotus. It has been shown in our first chapter how the elder dramatist delights in tracing events and institutions back to their first origin, and in following derivations through the steps of a genealogical sequence. Sophocles, on the other hand, limits himself to a close analysis of the action immediately represented, the motives by which his characters are in91fluenced, and the arguments by which their conduct is justified or condemned. We have already touched on the very different attitude assumed towards religion by these two great poets. Here we have only to add that while Aeschylus fills his dramas with supernatural beings, and frequently restricts his mortal actors to the interpretation or execution of a divine mandate, Sophocles, representing the spirit of Greek Humanism, only once brings a god on the stage, and dwells exclusively on the emotions of pride, ambition, revenge, terror, pity, and affection, by which men and women of a lofty type are actuated. Again (and this is one of his poetic superiorities), Aeschylus has an open sense for the external world; his imagination ranges far and wide from land to land; his pages are filled with the fire and light, the music and movement of Nature in a Southern country. He leads before us in splendid procession the starry-kirtled night; the bright rulers that bring round winter and summer; the dazzling sunshine; the forked flashes of lightning; the roaring thunder; the white-winged snow-flakes; the rain descending on thirsty flowers; the sea now rippling with infinite laughter, now moaning on the shingle, growing hoary under rough blasts, with its eastern waves dashing against the new-risen sun, or, again, lulled to waveless, windless, noonday sleep; the volcano with its volleys of fire-breathing spray and fierce jaws of devouring lava; the eddying whorls of dust; the resistless mountain-torrent; the meadow-dews; the flowers of spring and fruits of summer; the evergreen olive, and trees that give leafy shelter from dogstar heat. For all this world of wonder and beauty Sophocles offers only a few meagre allusions to the phenomena presented by sunshine and storm. No poet has ever so entirely concentrated his attention on human deeds and human passions. Only the grove of Col?nus, interwoven with his own earliest recollections, had power to draw from him, in extreme old age, a song such as the nightingale might have warbled amid those92 inviolable recesses where the ivy and laurel, the vine and olive gave a never-failing shelter against sun and wind alike. Yet even this leafy covert is but an image of the poets own imagination, undisturbed by outward influences, self-involved, self-protected, and self-sustained. Of course, we are only restating in different language what has long been known, that the epic element of poetry, before so prominent, was with Sophocles entirely displaced by the dramatic; but if Sophocles became the greatest dramatist of antiquity, it was precisely because no other writer could, like him, work out a catastrophe solely through the action of mind on mind, without any intervention of physical force; and if he possessed this faculty, it was because Greek thought as a whole had been turned inward; because he shared in the devotion to psychological studies equally exemplified by his younger contemporaries, Protagoras, Thucydides, and Socrates, all of whom might have taken for their motto the noble linesLOUVAIN UNDER THE MAILED FISTIt is worthy of remark that in the Platonic Er?s we have the germor something more than the germof Aristotles whole metaphysical system.135 According to the usual law of speculative evolution, what was subjective in the one becomes objective in the other. With Plato the passion for knowledge had been merely the guiding principle of a few chosen spirits. With Aristotle it is the living soul of Nature, the secret spring of movement, from the revolution of the outermost starry sphere to the decomposition and recomposition of our mutable terrestrial elements; and from these again through the whole scale of organic life, up to the moral culture of man and the search for an ideally-constituted state. What enables all these myriad movements to continue through eternity, returning ever in an unbroken circle on themselves, is the yearning of unformed matterthat is to say, of unrealised powertowards the absolute unchanging actuality, the self-thinking thought, unmoved, but moving every other form of existence by the desire to participate in its ineffable perfection. Born of the Hellenic enthusiasm for beauty, this wonderful conception subsequently became incorporated with the official teaching of Catholic theology. What had once been a theme219 for ribald merriment or for rhetorical ostentation among the golden youth of Athens, furnished the motive for his most transcendent meditations to the Angel of the Schools; but the fire which lurked under the dusty abstractions of Aquinas needed the touch of a poet and a lover before it could be rekindled into flame. The eyes of Beatrice completed what the dialectic of Plato had begun; and the hundred cantos of her adorer found their fitting close in the love that moves the sun and the other stars.
