"There is one which I should prefer to all others, The History of the Liberty of the Swiss, of that independence which a brave people rescued from the House of Austria, defended against a Dauphin of France, and finally sealed with the blood of Charles of Burgundy. From such a theme, so full of public spirit, of military glory, of examples of virtue, of lessons of government, the dullest stranger would catch fire; what might not I hope, whose talents, whatsoever they may be, would be inflamed with the zeal of patriotism. But the materials of this history are inaccessible to me, fast locked in the obscurity of an old barbarous German dialect, of which I am totally ignorant, and which I cannot resolve to learn for this sole and peculiar purpose. "I have another subject in view, which is the contrast of the former history: the one a poor, warlike, virtuous republic, which emerges into glory and freedom; the other a commonwealth, soft, opulent, and corrupt; which, by just degrees, is precipitated from the abuse to the loss of her liberty: both lessons are, perhaps, equally instructive. This second subject is, The History of the Republic of Florence under the House of Medicis: a period of one hundred and fifty years, which rises or descends from the dregs of the Florentine democracy, to the title and dominion of Cosmo de Medicis in the Grand Duchy of Tuscany. I might deduce a chain of revolutions not unworthy of the pen of Vertot; singular men, and singular events; the Medicis four times expelled, and as often recalled; and the Genius of Freedom reluctantly yielding to the arms of Charles V. and the policy of Cosmo. The character and fate of Savanerola, and the revival of arts and letters in Italy, will be essentially connected with the elevation of the family and the fall of the republic. The Medicis (stirps quasi fataliter nata ad instauranda vel fovenda studia (Lipsius ad Germanos et Galles, Epist. viii.)) were illustrated by the patronage of learning; and enthusiasm was the most formidable weapon of their adversaries. On this splendid subject I shall most probably fix; but when, or where, or how will it be executed? I behold in a dark and doubtful perspective." Res alta terra, et caligine mersas.
