5. Shakspeare, in common with his comrades, esteemed the mass of old plays, waste stock, in which any experiment could be freely tried. Had the _prestige_[541] which hedges about a modern tragedy existed, nothing could have been done. The rude warm blood of the living England circulated in the play, as in street-ballads, and gave body which he wanted to his airy and majestic fancy. The poet needs a ground in popular tradition on which he may work, and which, again, may restrain his art within the due temperance. It holds him to the people, supplies a foundation for his edifice; and, in furnishing so much work done to his hand, leaves him at leisure, and in full strength for the audacities of his imagination. In short, the poet owes to his legend what sculpture owed to the temple. Sculpture in Egypt, and in Greece, grew up in subordination to architecture. It was the ornament of the temple wall: at first, a rude relief carved on pediments, then the relief became bolder, and a head or arm was projected from the wall, the groups being still arranged with reference to the building, which serves also as a frame to hold the figures; and when, at last, the greatest freedom of style and treatment was reached, the prevailing genius of architecture still enforced a certain calmness and continence in the statue. As soon as the statue was begun for itself, and with no reference to the temple or palace, the art began to decline: freak, extravagance, and exhibition, took the place of the old temperance. This balance-wheel, which the sculptor found in architecture, the perilous irritability of poetic talent found in the accumulated dramatic materials to which the people were already wonted, and which had a certain excellence which no single genius,[542] however extraordinary, could hope to create.
