The poetry of Aristophanes is always swift and splendid. We watch its brilliant course as we might watch the flight of a strong, rapid bird, whose plumage glitters by moments in the light of the sun; for, to insist upon the metaphor, the dazzling radiance of his fancy only shines at intervals, capriciously, with fitful flashes, coruscating suddenly and dying out again. It is as if the neck alone and a portion of the feathers of the soaring bird were flecked with gold and crimson grain, so that a turn of the body or a fluttering of the pinions is enough to bring the partial splendor into light or cast it into shadow. Aristophanes passes by abrupt transitions from the coarsest or most simply witty dialogue to passages of pure and plaintive song; he quits his fiercest satire for refreshing strains of lark-like heaven-aspiring melody. These, again, he interrupts with sudden ruthlessness, breaking the melody in the middle of a bar, and dropping the unfinished stanza. He seems shy of giving his poetic impulse free rein, and prefers to tantalize[117] us with imperfect specimens of what he might achieve; so that his splendor is like that of northern streamers in its lambency, though swift and piercing as forked lightnings in its intensity. Even his most impassioned and sustained flights of imagination are broken by digressions into satire, fantastic merriment, or parody, by which the more dull-witted Athenians must have been sorely puzzled in their inability to decide on the serious or playful purpose of the poet. Perhaps the most splendid passages of true poetry in Aristophanes are the choruses of the initiated in the _Frogs_, the Chorus of the Clouds before they appear upon the stage, the invitation to the nightingale, and the parabasis of the Birds, the speech of Dikaios Logos in the _Clouds_, some of the praises of rustic life in the _Peace_, the serenade (notwithstanding its coarse satire) in the _Ecclesiazusæ_, and the songs of Spartan and Athenian maidens in the _Lysistrata_. The charm of these marvellous lyrical episodes consists in their perfect simplicity and freedom. They seem to be poured forth as "profuse strains of unpremeditated art" from the fulness of the poet's soul. Their language is elastic, changeful, finely tempered, fitting the delicate thought like a veil of woven air. It has no Pindaric involution, no Æschylean pompousness, no studied Sophoclean subtlety, no Euripidean _concetti_. It is always bright and Attic, sparkling like the many-twinkling laughter of the breezy sea, or like the light of morning upon rain-washed olive-branches. But this poetry is never very deep or passionate. It cannot stir us with the intensity of Sappho, with the fire and madness of the highest inspiration. Indeed, the conditions of comedy precluded Aristophanes, even had he desired it, which we have no reason to suspect, from attempting the more august movements of lyric poetry. The peculiar glories of his style are its untutored beauties, the improvised perfection and unerring exactitude of natural expression, for which it is unparalleled by that of any other Greek poet. In her most delightful moments the muse of Aristophanes suggests an almost plaintive pathos, as if behind the comic mask there were a thinking, feeling human soul, as if the very uproar of the Bacchic merriment implied some after-thought of sadness.
