127. There is a beautiful "investment of capital" for your modern merchant to study! No interest thought of, and little hope of ever getting back the principal. And yet you will find that there were no mercantile "panics," in Florence in those days, nor failing bankers, [1] nor "clearings out of this establishment--any reasonable offer accepted." [Footnote: Some account of the state of modern British business in this kind will be given, I hope, in some number of "Fors Clavigera" for this year, 1874.] 128. But the second story, of a private Florentine citizen, is better still. In that campaign against Pisa in which the florins were struck on the root of pine, the conditions of peace had been ratified by the surrender to Florence of the Pisan fortress of Mutrona, which commanded a tract of seaboard below Pisa, of great importance for the Tuscan trade. The Florentines had stipulated for the right not only of holding, but of destroying it, if they chose; and in their Council of Ancients, after long debate, it was determined to raze it, the cost of its garrison being troublesome, and the freedom of seaboard all that the city wanted. But the Pisans feeling the power that the fortress had against them in case of future war, and doubtful of the issue of council at Florence, sent a private negotiator to the member of the Council of Ancients who was known to have most influence, though one of the poorest of them, Aldobrandino Ottobuoni; and offered him four thousand golden florins if he would get the vote passed to raze Mutrona. The vote _had_ passed the evening before. Aldobrandino dismissed the Pisan ambassador in silence, returned instantly into the council, and without saying anything of the offer that had been made to him, got them to reconsider their vote, and showed them such reason for keeping Mutrona in its strength, that the vote for its destruction was rescinded. "And note thou, oh reader," says Villani, "the virtue of such a citizen, who, not being rich in substance, had yet such continence and loyalty for his state." 129. You might, perhaps, once, have thought me detaining you needlessly with these historical details, little bearing, it is commonly supposed, on the subject of art. But you are, I trust, now in some degree persuaded that no art, Florentine or any other, can be understood without knowing these sculptures and mouldings of the national soul. You remember I first begun this large digression when it became a question with us why some of Giovanni Pisano's sepulchral work had been destroyed at Perugia. And now we shall get our first gleam of light on the matter, finding similar operations carried on in Florence. For a little while after this speech in the Council of Ancients, Aldobrandino died, and the people, at public cost, built him a tomb of marble, "higher than any other" in the church of Santa Reparata, engraving on it these verses, which I leave you to construe, for I cannot:--
