You have only once to turn over the leaves of Lionardo's sketch book, in the Ambrosian Library, to see how carpentry is connected with engineering,—the architect was always a stonecutter, and the stonecutter not often practically separate, as yet, from the painter, and never so in general conception of function. You recollect, at a much later period, Kent's description of Cornwall's steward:

"KENT. You cowardly rascal!—nature disclaims in thee, a tailor made thee!

CORNWALL. Thou art a strange fellow—a tailor make a man?

KENT. Ay, sir; a stonecutter, or a painter, could not have made him so ill; though they had been but two hours at the trade."

71. You may consider then this group of artizans with the merchants, as now forming in each town an important Tiers Etat, or Third State of the people, occupied in service, first, of the ecclesiastics, who in monastic bodies inhabited the cloisters round each church; and, secondly, of the knights, who, with their retainers, occupied, each family their own fort, in allied defence of their appertaining streets.

72. A Third Estate, indeed; but adverse alike to both the others, to Montague as to Capulet, when they become disturbers of the public peace; and having a pride of its own,—hereditary still, but consisting in the inheritance of skill and knowledge rather than of blood,—which expressed the sense of such inheritance by taking its name habitually from the master rather than the sire; and which, in its natural antagonism to dignities won only by violence, or recorded only by heraldry, you may think of generally as the race whose bearing is the Apron, instead of the shield.

73. When, however, these two, or in perfect subdivision three, bodies of men, lived in harmony,—the knights remaining true to the State, the clergy to their faith, and the workmen to their craft,—conditions of national force were arrived at, under which all the great art of the middle ages was accomplished. The pride of the knights, the avarice of the priests, and the gradual abasement of character in the craftsman, changing him from a citizen able to wield either tools in peace or weapons in war, to a dull tradesman, forced to pay mercenary troops to defend his shop door, are the direct causes of common ruin towards the close of the sixteenth century.

74. But the deep underlying cause of the decline in national character itself, was the exhaustion of the Christian faith. None of its practical claims were avouched either by reason or experience; and the imagination grew weary of sustaining them in despite of both. Men could not, as their powers of reflection became developed, steadily conceive that the sins of a life might be done away with, by finishing it with Mary's name on the lips; nor could tradition of miracle for ever resist the personal discovery, made by each rude disciple by himself, that he might pray to all the saints for a twelvemonth together, and yet not get what he asked for.

75. The Reformation succeeded in proclaiming that existing Christianity was a lie; but substituted no theory of it which could be more rationally or credibly sustained; and ever since, the religion of educated persons throughout Europe has been dishonest or ineffectual; it is only among the labouring peasantry that the grace of a pure Catholicism, and the patient simplicities of the Puritan, maintain their imaginative dignity, or assert their practical use.

76. The existence of the nobler arts, however, involves the harmonious life and vital faith of the three classes whom we have just distinguished; and that condition exists, more or less disturbed, indeed, by the vices inherent in each class, yet, on the whole, energetically and productively, during the twelfth, thirteenth, fourteenth, and fifteenth centuries. But our present subject being Architecture only, I will limit your attention altogether to the state of society in the great age of architecture, the thirteenth century. A great age in all ways; but most notably so in the correspondence it presented, up to a just and honourable point, with the utilitarian energy of our own days.
