Aeschylus flourished in the very freshness and vigour of Grecian freedom, and a proud sense of the glorious struggle by which it was won, seems to have animated him and his poetry. He had been an eye-witness of the greatest and most glorious event in the history of Greece, the overthrow and annihilation of the Persian hosts under Darius and Xerxes, and had fought with distinguished bravery in the memorable battles of Marathon and Salamis. In the _Persians_ he has, in an indirect manner, sung the triumph which he contributed to obtain, while he paints the downfall of the Persian ascendancy, and the ignominious return of the despot, with difficulty escaping with his life, to his royal residence. The battle of Salamis he describes in the most vivid and glowing colours. Through the whole of this piece, and the _Seven before Thebes_, there gushes forth a warlike vein; the personal inclination of the poet for a soldier's life, shines throughout with the most dazzling lustre. It was well remarked by Gorgias, the sophist, that Mars, instead of Bacchus, had inspired this last drama; for Bacchus, and not Apollo, was the tutelary deity of tragic poets, which, on a first view of the matter, appears somewhat singular, but then we must recollect that Bacchus was not merely the god of wine and joy, but also the god of all higher kinds of inspiration.
Among the remaining pieces of Aeschylus, we have what is highly deserving of our attention--a complete _Trilogy_. The antiquarian account of the trilogies is this: that in the more early times the poet did not contend for the prize with a single piece, but with three, which, however, were not always connected together in their subjects, and that to these was added a fourth,--namely, a _satiric drama_. All were acted in one day, one after another. The idea which, in relation to the tragic art, we must form of the trilogy, is this: a tragedy cannot be indefinitely lengthened and continued, like the Homeric Epos for instance, to which whole rhapsodies have been appended; tragedy is too independent and complete within itself for this; nevertheless, several tragedies may be connected together in one great cycle by means of a common destiny running through the actions of all. Hence the restriction to the number three admits of a satisfactory explanation. It is the thesis, the antithesis, and the synthesis. The advantage of this conjunction was that, by the consideration of the connected fables, a more complete gratification was furnished than could possibly be obtained from a single action. The subjects of the three tragedies might be separated by a wide interval of time, or follow close upon one another.
