The treaty of Lodi, to which Sforza had been mainly instrumental, remained in force at his death; indeed, historians dwell with peculiar pleasure on the twenty-eight years of tranquillity which succeeded that settlement. Compared with the turmoil of preceding wars, or with the clang of battles, which, from 1492 till 1529 rang continually through the Peninsula, these were, indeed, years of repose and prosperity, and may be considered the halcyon age of modern Italy. It is true that those republican institutions had been widely infringed under which her communities rose to eminence, and that arbitrary sovereigns had with more or less success established over most of them a personal or hereditary sway. True also, that her newly awakened spirit of philosophy had then assumed, under the influence of the ancient classics, a somewhat unprofitable direction; that "the all-immortal three" of the preceding century already had raised her literature to perhaps its culminating point; and that it was not until the following age that her arts attained their highest perfection. But whilst individual freedom had been curtailed, individual security had been generally enlarged; even the despotism of one was welcomed, when it brought relief from the storms of faction and the tyranny of mobs. The reviving energies of mind felt the invigoration which succeeds to long repose, but still glowed with a healthy character, free from that infusion of meaner motives and more degrading tendencies which too quickly and permanently poisoned the fairest creations of the pen, the pencil, and the chisel. Above all, Italy in the fifteenth century was as yet independent. Her bright plains had not become battle-fields for European ambition; her treasures had not been plundered, her civilisation trampled upon, her nationality defaced by foreign and barbarous invaders. Yet the pæans of peace inspired by the interval of comparative quiet upon which we are now entering must be read with poetical allowance, for we shall have to trace during that period not unfrequent intrigues, and to mention many, ebullitions of "The mind of Italy to strife inflamed."
