The period which intervened between the birth of Pericles and the death of Aristotle, is undoubtedly, whether considered in itself, or with reference to the effects which it has produced upon the subsequent destinies of civilized man, the most memorable in the history of the world. What was the combination of moral and political circumstances which produced so unparalleled a progress during that period in literature and the arts;--why that progress, so rapid and so sustained, so soon received a check, and became retrograde,--are problems left to the wonder and conjecture of posterity. The wrecks and fragments of those subtle and profound minds, like the ruins of a fine statue, obscurely suggest to us the grandeur and perfection of the whole. Their very language--a type of the understandings of which it was the creation and the image--in variety, in simplicity, in flexibility, and in copiousness, excels every other language of the western world. Their sculptures are such as we, in our presumption, assume to be the models of ideal truth and beauty, and to which no artist of modern times can produce forms in any degree comparable. Their paintings, according to Pliny and Pausanias, were full of delicacy and harmony; and some even were powerfully pathetic, so as to awaken, like tender music or tragic poetry, the most overwhelming emotions. We are accustomed to conceive the painters of the sixteenth century, as those who have brought their art to the highest perfection, probably because none of the ancient paintings have been preserved. For all the inventive arts maintain, as it were, a sympathetic connexion between each other, being no more than various expressions of one internal power, modified by different circumstances, either of an individual, or of society; and the paintings of that period would probably bear the same relation as is confessedly borne by the sculptures to all succeeding ones. Of their music we know little; but the effects which it is said to have produced, whether they be attributed to the skill of the composer, or the sensibility of his audience, are far more powerful than any which we experience from the music of our own times; and if, indeed, the melody of their compositions were more tender and delicate, and inspiring, than the melodies of some modern European nations, their superiority in this art must have been something wonderful, and wholly beyond conception.
