commemorating the building of the church to which we have before referred. Here stands Sisinius, and whether he be the hero of St. Clement's miracle, as Father Mulroody asserts, or not, he is certainly a Master architect standing in his toga, and wearing a Freemason's apron under it, directing his men, Albertus, Cosma, and Carvoncelle, in the moving of a column. The figures in this are so much more rude and out of drawing than the ones above, that they scarcely would seem to be by the same hands. I account for it by the fact that in representing a natural sketch from real life, the artist had no traditionary models to guide him, as he had for his saints and virgins, and consequently he found it difficult to depict his fellow-workmen in complicated attitudes. The art of the Catacombs has no affinity with these frescoes, which are of a more free and natural style, and the true ancestors of the Tuscan school of fresco-painting. [Illustration: FRESCOES OF THE 8TH CENTURY IN THE SUBTERRANEAN CHURCH OF S. CLEMENTE, ROME, WITH PORTRAITS OF THE PATRON BENO DI RAPIZO AND HIS FAMILY. _See pages 10 and 268._] We might place these as the earliest revival of nature after the Byzantine conventional influence was withdrawn; the next link is to be seen in the church of S. Piero a Grado, three miles from Pisa, where are extant by far the finest specimens of Comacine fresco-painting. The church, which I have described in the chapter on the Carlovingian era, was built soon after the time of Pope Leo III. (795-816). The frescoes are said to date before A.D. 1000. Like those of St. Clement they are not Byzantine, and yet, though full of life and action, they have an Eastern air; they are not like the later Tuscan art, the colouring being lighter and the drawing of the figures different. The prevailing tint is a beautiful ethereal pale green, which is like nothing in Tuscan art, though Peruzzi produced a tint something like it in the sixteenth century. Standing at one end of the church and looking down the nave, one could imagine a Ravenna church, with its mosaics softened and toned down into frescoes. They are a valuable proof that among the Comacine Masters pictorial decoration was considered an integral part of a building. They told the articles of their creed in their sculptures outside, but they wrote the history of the church on the walls inside. The story of the church in the abstract is told in the line of popes above the arches, ending at Leo III.; the story of this church in particular is told in large scenes above them. Here is the church as it looked when built, and here is the ship of St. Peter cast ashore at Grado, and his preaching and baptizing, imprisonment, etc. In fact all his life still glows, though fading out on the south wall. The north wall is given to his death and miracles. Here is his crucifixion, near an obelisk on the Janicular Hill, and the beheading of his fellow-martyr St. Paul at the Tre
