"Well, my dear, if it is to be a real lecture, we will suppose this gravel path to be my platform, and your father and yourselves to be my highly respectable and most intelligent audience; and so, making my bow to the company, I will begin.—There is considerable uncertainty as to the origin of these tiles. Most people suppose that the old Roman tessellated pavement suggested the idea of representing figures on tiles. But we may imagine them to be merely the result of successive improvements. First, there was the rude tile or brick; then, in very early times, the makers impressed their own particular marks upon them; and from this simple practice we can easily imagine the gradual introduction of the elaborate patterns you were looking at in the church."

"If you please, Mr. Ambrose," said Constance, "will you tell us what was the Roman tessellated pavement?"

"It was composed of a number of square pieces of hard-burnt clay, like dice, of different colours; these were arranged to form a pattern, and then firmly fixed in very strong cement. They were exceedingly durable, and often of most elegant design. When found in the ruins of Roman villas, which they frequently are, they generally appear almost as fresh as when they were put down. Tessellated or mosaic pavements are to be found in a few old churches; the most beautiful now existing in England, are in Westminster Abbey, and in Canterbury Cathedral, near the tomb of Thomas à Becket."

"But don't you think it probable," inquired Mr. Acres, "if these tiles date pretty nearly back to the time when the mosaic pavement was used, that the pavement suggested the tiles? there seems to be some similarity of pattern, and I noticed that in one part of the church there are plain tiles of different colours arranged so as to form a pattern[51], which seems, on a larger scale, a close imitation of the mosaic pavement."

"It may be so; and this view seems confirmed by the circumstance that in some foreign churches the tiles are mixed in the same pavement with mosaic work. It certainly seems a natural transition from the one to the other.

Encaustic tiles exist in abundance and great beauty in Normandy; and though, as I have said, we cannot fix a precise date to their introduction, it seems not improbable that we are indebted to that country for the first idea of using them in the pavement of our churches, since in some instances they appear to be coeval with the erection of the Norman churches in which they are found. Some have upon them the semi-circular headed arch, which is characteristic of Norman times; and as no doubt the later tiles frequently indicate by their patterns the period of ecclesiastical architecture to which they may be referred, most likely these may be equally relied upon as marking the Norman period. In Ireland, tiles of this date are more common than in this country. Their general use, however, has prevailed among us from about A.D. 1250 to A.D. 1550, and the finest and most interesting specimens we have remaining are at Gloucester and Malvern.

There are several different kinds of ornamental pavement of which specimens remain. In the ruins of Fountains Abbey are specimens having the pattern pierced through the entire tile, and afterwards filled in with clay of another colour. At Canterbury there are circles of stone pavement with patterns cut in relief, the spaces being filled in with dark cement. In the early stages of the art the pattern of the tiles was sometimes left in relief, the tile being of one colour only, but the uneven surface was found to be very inconvenient for walking upon. Encaustic tiles—so called because the patterns are burnt into them—are by far the most common sort of tile pavement in our English churches, especially in the southern and western counties."

"I suppose, Mr. Ambrose," said Constance, "that the tiles in our church are of that sort?"
