Indeed, there is no one of Shakspeare's plays harder to characterize. The name and the remembrances connected with it, prepare us for the representation of attachment no less faithful than fervent on the side of the youth, and of sudden and shameless inconstancy on the part of the lady. And this is, indeed, as the gold thread on which the scenes are strung, though often kept out of sight and out of mind by gems of greater value than itself. But as Shakspeare calls forth nothing from the mausoleum of history, or the catacombs of tradition, without giving, or eliciting, some permanent and general interest, and brings forward no subject which he does not moralize or intellectualize,--so here he has drawn in Cressida the portrait of a vehement passion, that, having its true origin and proper cause in warmth of temperament, fastens on, rather than fixes to, some one object by liking and temporary preference. There's language in her eye, her cheek, her lip, Nay, her foot speaks; her wanton spirits look out At every joint and motive of her body. This Shakspeare has contrasted with the profound affection represented in Troilus, and alone worthy the name of love;--affection, passionate indeed,--swoln with the confluence of youthful instincts and youthful fancy, and growing in the radiance of hope newly risen, in short enlarged by the collective sympathies of nature;--but still having a depth of calmer element in a will stronger than desire, more entire than choice, and which gives permanence to its own act by converting it into faith and duty. Hence with excellent judgment, and with an excellence higher than mere judgment can give, at the close of the play, when Cressida has sunk into infamy below retrieval and beneath hope, the same will, which had been the substance and the basis of his love, while the restless pleasures and passionate longings, like sea-waves, had tossed but on its surface,--this same moral energy is represented as snatching him aloof from all neighbourhood with her dishonour, from all lingering fondness and languishing regrets, whilst it rushes with him into other and nobler duties, and deepens the channel, which his heroic brother's death had left empty for its collected flood. Yet another secondary and subordinate purpose Shakspeare has inwoven with his delineation of these two characters,--that of opposing the inferior civilization, but purer morals, of the Trojans to the refinements, deep policy, but duplicity and sensual corruptions, of the Greeks.
