How is it to be prevented again? By trying to make the monuments of the past loved, by relating the tale of their building, by telling the life story of the builders. If we know them we must surely revere them, and when we have learned to know and to love, we have learned to be liberal. Archæology is _to teach us to remember_. Those who have gone before have passed on to us cathedral and town hall; it is our obligation to transmit them intact to those who come after. They are not ours to destroy. Art is the high-water mark reached by civilization; art does not speak in English, or in German, or in the Latin tongue, but in a language understood of all peoples and all times. To destroy a great monument of the past is to betray civilization. It was proved in 1914 that erudition is not safeguard enough, nor is enthusiasm, sighs 1793, nor purpose to reform, admits 1562. We must comprehend intelligently our own personal solidarity with the past. We must never look at a noble building without proudly realizing that we had a hand in its making. Battles then can rage around cathedrals without danger of their destruction. As in golden amber, the past will preserve them, the past which is yours and mine and everyone's heritage. It is a right instinct which makes a man treasure the home he has had transmitted to him through several generations. How much more--when loyalty is roused by an XVIII-century or a XVII-century habitation--should emotion be felt for what was reared from 1140 to 1270 by the very generations who began for us of to-day most of the big things we value: our universities, our literature, our political freedom, our prosperous trade. Now in the making of these infinitely precious things, France played the leading role. Put partisan feeling aside and acknowledge it honestly. "I believe," said Ruskin, in a lecture at Edinburgh, in 1853, even before the new science of mediæval archæology was formulated, "that the French nation in the XII and XIII centuries was the greatest nation in the world, and that the French not only invented Gothic architecture, but carried it to its noblest developments." French Gothic churches are a fountainhead, and should rank first. Because of them we have Westminster, Ely, and Lincoln, we had Tintern, Melrose, Mellifont, Holycross. They built the Burgos, Toledo, León, Seville, and Belem, which have given wings to the soul of the Peninsula. Because of the French cathedrals we have Cologne, Magdeburg, and Halberstadt, Vienna, Prague, Upsala, Siena, Florence, and Milan.
