Much more could be told of Trastevere and much has been told already; how Beatrice Cenci lies in San Pietro in Montorio, how the lovely Farnesina, with all its treasures, was bought by force by the Farnese for ten thousand and five hundred scudi,--two thousand and one hundred pounds,--how the Region was swept and pillaged again and again by Emperors and nobles, and people and Popes, without end. But he who should wander through the Regions in their order, knowing that the greatest is last, would tire of lingering in the long Lungara and by the Gate of the Holy Spirit, while on the other side lies the great Castle of Sant' Angelo, and beyond that the Vatican, and Saint Peter's church; and for that matter, a great part of what has not been told here may be found in precise order and ready to hand in all those modern guide books which are the traveller's first leading-strings as he learns to walk in Rome. * * * * * Yet here, on the threshold of that Region which contains many of the world's most marvellous treasures of art--at the Gate of the Holy Spirit, through which Raphael so often passed between love and work--I shall say a few words about that development in which Italy led the world, and something of the men who were leaders in the Renascence. Art is not dependent on the creations of genius alone. It is also the result of developing manual skill to the highest degree. Without genius, works of art might as well be turned out by machinery; without manual skill, genius could have no means of expression. As a matter of fact, in our own time, it is the presence of genius, without manual skill, or foolishly despising it, that has produced a sort of school called the impressionist. To go back to first principles, the word Art, as every child knows, is taken directly from the Latin ars, artis, which the best Latin dictionary translates or defines: 'The faculty of joining anything corporeal or spiritual properly or skilfully,' and therefore: 'skill, dexterity, art, ability,' and then: 'skill or faculty of the mind or body that shows itself in performing any work, trade, profession, art, science.' From the meaning of the Latin word we may eliminate what refers to spiritual things; not because literature, for instance, is not art, as well as music and the rest, but because we have to do with painting, sculpture, architecture, metal working, and the like, in which actual manual skill is a most integral element.
