And all this suddenly found vent in an immense shout that rose to the skies. Before us, on the screen which had but now been empty and bare as a stretch of sand, there had come into being, spontaneously, in a flash, hundreds and thousands of men, swarming in unspeakable confusion.

It was obviously the suddenness and complexity of the sight which so profoundly stirred the crowd. The sudden emergence of life innumerable out of nothingness convulsed it like an electric shock. In front of it, where there had been nothing, there now swarmed another crowd, dense as itself, a crowd whose excitement mingled with its own and whose uproar, which it was able to divine, was added to its own! For a few seconds I had the impression that it was losing its mental balance and swaying to and fro in an access of delirium.

However, the crowd once more regained its self-control. The need, not of understanding—it seemed not to care about that at first—but of seeing and grasping the entire manifestation of the phenomena mastered the force let loose in its midst. It became silent again. It gazed. And it listened.

Yonder—I dare not say on the screen, for, in truth, so abnormal were its dimensions that the picture overflowed the frame and was propelled into the space outside—yonder, that which had impressed us as being disorder and chaos became organized in accordance with a certain rhythm which at length grew perceptible to us. The movement to and fro was that of artisans performing a well-regulated task; and the task was accomplished about an immense fabric in the course of erection.

How all these artisans were clad in a fashion absolutely different from our own; and, on the other hand, the tools which they employed, the appearance of their ladders, the shape of their scaffoldings, their manner of carrying loads and of hoisting the necessary materials in wicker baskets to the upper floors, all these things, together with a multitude of further details, brought us into the heart of a period which must have been the thirteenth or fourteenth century.

There were numbers of monks supervising the works, calling out orders from one end of the vast site to the other, setting out measurements and not disdaining themselves to mix the mortar, to push a wheel-barrow or to saw a stone. Women of the people, uttering their cries at the top of their voices, walked about bearing jars of wine with which they filled cups that were at once emptied by the thirsty labourers. A beggar went by. Two tattered singers began to roar a ditty, accompanying themselves on a sort of guitar. And a troop of acrobats, all lacking an arm, or a leg, or both legs, were preparing to give their show, when the scene changed without any transition, like a stage setting which is altered by the mere pressure of a button.

What we now saw was the same picture of a building in process of construction. But this time we clearly distinguished the plan of the edifice, the whole base of a Gothic cathedral displaying its huge proportions. And on these courses of masonry, which had reached the lower level of the towers, and along the fronts and before the niches and on the steps of the porch, everywhere, in fact, swarmed stone-hewers, masons, sculptors, carpenters, apprentices and monks.

And the costumes were no longer the same. A century or two had passed.

Next came a series of pictures which succeeded one another without our being able to separate the one from the other or to ascribe a beginning or an end to any one of them. By a method no doubt similar to that which, on the cinematograph, shows us the growth of a plant, we saw the cathedral rising imperceptibly, blossoming like a flower whose exquisitely-moulded petals open one by one and, lastly, being completed before our eyes, all of itself, without any human intervention. Thus came a moment when it stood out against the sky in all its glory and harmonious strength. It was Rheims Cathedral, with its three recessed doorways, its host of statues, its magnificent rose-windows, its wonderful towers flanked by airy turrets, its flying buttresses and the lacework of its carvings and balconies, Rheims Cathedral such as the centuries had beheld it, before its mutilation by the Huns.

A long shudder passed through the crowd. It understood what those who were not present cannot easily be made to understand now, by means of insignificant words: it understood that in front of it there stood something other than the photographic presentment of a building; and, as it possessed the profound and accurate intuition that it was not the victim of an unthinkable hoax, it became imbued and overwhelmed by an utterly disturbing sense of witnessing a most prodigious spectacle: the actual erection of a church in the Middle Ages, the actual work of a thirteenth-century building-yard, the actual life of the monks and artists who built Rheims Cathedral. Enlightened by its subtle instinct, not for a second did it doubt the evidence of its eyes. What I had denied, or at least what I had admitted only as an illusion, with reservations and flashes of incredulity, the crowd accepted with a certainty against which it would have been madness to rebel. It had faith. It believed with religious fervour. What it saw was not an artificial evocation of the past but that past itself, revived in all its living reality.
