Simplicity, the second note of Æschylus, needs little demonstration after the detailed account of his plots. The four earlier works contain each the very minimum of action. The characterization is noble, but far from subtle. All the persons are simply drawn, deriving their effect from one informing concept and from the circumstances to which they react. Euripides in the _Frogs_[289] fastens upon this, remarking, “You took over from Phrynichus an audience who were mere fools”. A later generation demanded smartness and subtlety; Æschylus was anything but artful, and so the same critic accuses him of obscurity in his prologues.[290] The _Oresteia_ exhibits a marked advance in construction. Leaving on one side the vexed question of the plot in the _Agamemnon_,[291] we observe in the _Choephorœ_ what we may call intrigue. Orestes has a device for securing admission to the palace; the libations by which Clytæmnestra intends to secure herself are turned into a weapon against her; the chorus intercept the nurse and alter her message so as to aid the conspiracy. This ingenuity is perhaps due to the influence of Sophocles. Thirdly, what may be termed picturesqueness in structure is a matter of vital import for Æschylus. To write dramatically is to portray life by exhibiting persons, the vehicles of principles, in contact and collision. For an artist of the right bent, it is not difficult to select a scene of history or an imagined piece of contemporary life which under manipulation and polishing will show the hues of drama. But the earliest of dramatists turns aside in the main from such topics. His favourite themes are the deepest issues, not of individual life, but the life of the race, or the structure of the universe. What is the relation between Justice and Mercy? Why is the omnipotent omniscient? May a man of free will and noble instincts escape a hereditary curse sanctioned by heaven? Such musings demand surely a quiet unhurried philosophic poem, not the decisive shock of drama. Æschylus devoted himself, nevertheless, not to literature in the fashion of Wordsworth, but to tragedy. How was he to write a play about Justice and Mercy, to discuss a compromise between the rigidity of safe government and the flexibility of wise government? Justice and Mercy are both essential to the moral universe, says the theologian—but they are incompatible. Friendship and strife are both essential to the physical universe, says Empedocles—but how can they be wedded? This impossibility is everywhere, and everywhere by miracle it is achieved. This union of opposites pervades the world, from the primitive protoplasm which must be rigid to resist external shock but flexible to grow and reproduce itself, to the august constitution of the eternal kingdom in which “righteousness and peace have kissed each other”. Where, then, is the playwright to find foothold? His innumerable instances merge into one another. Æschylus, with noble audacity, lifts us out of
