AESOP.--To this period (albeit somewhat at hazard) it is possible to ascribe Aesop, about whom nothing is known except that he wrote the fables which have been imitated from generation to generation. The collection that we possess under his name is one of these imitations, perpetrated long after his death, but as to which it is impossible to assign a date. PINDAR.--Pindar, the Theban, broadened and extended the lyrical type. Under him it preserved its power, its high spirits, its verse and, so to say, its fine fury; but he introduced into the epic the narration of ancient legends, the acts and gestures of the ancient heroes, and effected this so admirably that the most lyrical of Grecian lyricists is an historian. Capable of sustained elevation, of sublime thoughts and expressions, of a fine disorder which has been overpraised, and which on close expression is found to be very careful, he has been regarded as the very type of dignified and poetic style, and more or less to be imitated by all ambitious poets commencing with Ronsard. The wise, like Horace, have contented themselves with praising him. From fragments left to us he is infinitely impassioned to read. GREEK TRAGEDY.--Greek tragedy, which is one of the miracles of the human brain, began in the sixth century B.C. It was born of the dithyramb. The dithyramb is a chant in chorus in honour of a god or a hero. From this chorus emerged a single actor who sang the praises of the god, and to which the choir replied. When, instead of one actor, there were two who addressed one another in dialogue and were answered by the choir, the dramatic poem was founded. When there were three--and there were hardly ever any more--tragedy, as the Greeks understood it, existed. THESPIS; AESCHYLUS; SOPHOCLES.--Thespis was the earliest known to us who took rudimentary tragedies from town to town in Attica. Then came Aeschylus, whose tragedy, already rigid and hieratical, was very powerful, imbued with terrible majesty; then came Sophocles, a religious philosopher, having a feeling for the old religion and the art of giving it a moral character, great lyrical poet, master of dialogue, eloquent, moving, knowing how to construct and carry on a dramatic poem with infinite skill, to whom, in fact, can be denied no quality of dramatic poetry and who attains a conception of perfection. EURIPIDES.--Euripides, less religious as a philosopher, sometimes suggesting the sophist and a little the rhetorician, but full of ideas, eloquent, affecting, "the most tragic" (that is, the most pathetic) of all the acting dramatists, as Aristotle observed, the most modern, too, and the one we best understand, has been the true source whence have been freely drawn the tragedies of modern times, more particularly of our own.
