The process of casting in plaster, in our acceptation of the phrase, is of modern origin, and so far as we know was invented in the fifteenth century, a little before the time of Verrocchio (1432–1488), the master of Leonardo da Vinci. He was among the first who employed it, and may fairly be said to have introduced it. At all events, the first clear mention of this process of which we are aware is by Vasari in his life of Verrocchio; and he states that this sculptor and painter “cast hands, knees, feet, legs, even torsi, in order to copy them at his leisure; and that soon after casts began to be made from the faces of persons after death, so that one sees in every house in Florence, on mantel-pieces, doors, windows, and cornices, a great number of these portraits, which seem alive.” For some time after it seems to have been used chiefly for taking casts from dead faces,—or hands and feet,—and not to have been applied to casting from models of clay. The general practice of that period was to make a small model in clay, then to bake it, and from this model by proportional compasses to enlarge it and point it upon the marble. The process of casting from clay models seems not to have been practiced then, and so far as we know models of full size in clay were rarely if ever made, until rather a comparatively recent period. A CONVERSATION WITH MARCUS AURELIUS. It was a dark and stormy night in December. Everybody in the house had long been in bed and asleep; but, deeply interested in the “Meditations of Marcus Aurelius,” I had prolonged my reading until the small hours had begun to increase, and I heard the bells of the Capucin convent strike for two o’clock. I then laid down my book, and began to reflect upon it. The fire had nearly burned out, and, unwilling yet to go, I threw on to it a bundle of canne and a couple of sticks; again the fresh flame darted out, and gave a glow to the room. Outside, the storm was fierce and passionate. Gusts beat against the panes, shaking the old windows of the palace, and lashing them with wild rain. At intervals a sudden blue light flashed through the room, followed by a trampling roar of thunder overhead. The fierce libeccio howled like a wild beast around the house, as if in search of its prey, and then died away, disappointed and growling, and after a short interval again leaped with fresh fury against the windows and walls, as if maddened by their resistance. As I sat quietly gazing into the fire and musing on many shadows of thought that came and passed, my imagination went back into the far past, when Marcus Aurelius led his legions against the Quadi, the Marcomanni, and the Sarmati, and brought before me the weather-beaten tent in which he sat so many a bleak and bitter night, after the duty of the day was done, and all his men had retired to rest, writing in his private diary those noble meditations, which, though meant solely for his private eye, are one of the most precious
