=The Mosaics.=--Stephen Wren tells us that his grandfather intended his great building to be adorned with mosaic work, and that one of his numerous disappointments was his inability, thanks to the ignorant opposition of the Commission, to carry out this intention. The categorical statement of the grandson is corroborated by (_a_) the text of various Acts of Parliaments, (_b_) other Renaissance Churches and notably St. Peter's, (_c_) the use of material softer than Portland stone for various surfaces.[103] Bishop Newton, who was Dean a hundred and twenty years ago, roundly accused the authorities of filching the decoration funds for William's wars. Queen Anne's wars would have sounded more probable. It was not until our own day that in this respect, as in others, the Surveyor's ideas have been carried out. The eight spandrels of soft and suitable stone have designs of the four Greater Prophets, and the four Evangelists, executed by Dr. Salviati of Venice. For the designs of St. Matthew and St. John the authorities were fortunate enough to secure the services of that wonderful Academician, Mr. G.F. Watts. He thoroughly understood and overcame the difficulty of the great distance of the spectator on the pavement below. These designs are in every way worthy of the painter of the Rider on the White Horse, and its fellows. The other Evangelists were designed by Mr. Brittan, and the Prophets by Mr. A. Stevens. The smoke should never be allowed to mar the colouring, and so injure the good effect, of this part of the scheme of decoration.
