And observe, there could be no monotony, no exhaustibleness, in the scenes required to be thus pourtrayed. Even if there were, and you wanted for every school in the kingdom, one death of Leonidas; one battle of Marathon; one death of Cleobis and Bito; there need not therefore be more monotony in your art than there was in the repetition of a given cycle of subjects by the religious painters of Italy. But we ought not to admit a cycle at all. For though we had as many great schools as we have great cities (one day I hope we _shall_ have), centuries of painting would not exhaust, in all the number of them, the noble and pathetic subjects which might be chosen from the history of even one noble nation. But, besides this, you will not, in a little while, limit your youths' studies to so narrow fields as you do now. There will come a time--I am sure of it--when it will be found that the same practical results, both in mental discipline, and in political philosophy, are to be attained by the accurate study of mediaeval and modern as of ancient history; and that the facts of mediaeval and modern history are, on the whole, the most important to us. And among these noble groups of constellated schools which I foresee arising in our England, I foresee also that there will be divided fields of thought; and that while each will give its scholars a great general idea of the world's history, such as all men should possess--each will also take upon itself, as its own special duty, the closer study of the course of events in some given place or time. It will review the rest of history, but it will exhaust its own special field of it; and found its moral and political teaching on the most perfect possible analysis of the results of human conduct in one place, and at one epoch. And then, the galleries of that school will be painted with the historical scenes belonging to the age which it has chosen for its special study. So far, then, of art as you may apply it to that great series of public buildings which you devote to the education of youth. The next large class of public buildings in which we should introduce it, is one which I think a few years more of national progress will render more serviceable to us than they have been lately. I mean, buildings for the meetings of guilds of trades. And here, for the last time, I must again interrupt the course of our chief inquiry, in order to state one other principle of political economy, which is perfectly simple and indisputable; but which, nevertheless, we continually get into commercial embarrassments for want of understanding; and not only so, but suffer much hindrance in our commercial discoveries, because many of our business men do not practically admit it.
