The fame of Claude Lorraine is partly explained by his indefatigable industry. Born at Champagne, in Lorraine, of poor parents, he was first apprenticed to a pastrycook. His brother, who was a wood-carver, afterwards took him into his shop to learn that trade. Having there shown indications of artistic skill, a travelling dealer persuaded the brother to allow Claude to accompany him to Italy. He assented, and the young man reached Rome, where he was shortly after engaged by Agostino Tassi, the landscape painter, as his house-servant. In that capacity Claude first learnt landscape painting, and in course of time he began to produce pictures. We next find him making the tour of Italy, France, and Germany, occasionally resting by the way to paint landscapes, and thereby replenish his purse. On returning to Rome he found an increasing demand for his works, and his reputation at length became European. He was unwearied in the study of nature in her various aspects. It was his practice to spend a great part of his time in closely copying buildings, bits of ground, trees, leaves, and such like, which he finished in detail, keeping the drawings by him in store for the purpose of introducing them in his studied landscapes. He also gave close attention to the sky, watching it for whole days from morning till night, and noting the various changes occasioned by the passing clouds and the increasing and waning light. By this constant practice he acquired, although it is said very slowly, such a mastery of hand and eye as eventually secured for him the first rank among landscape painters.
