Claude Lorrain Paintings, Bio, Ideas - The Art Story
Summary of Claude Lorrain
Claude Lorrain made paintings in which the sun, earth, and water seem to reverberate with emotion. His name is inseparable from seventeenth-century landscape painting, his works characterized by a Baroque classicism which is especially evident in his depiction of antique architecture, and his emphasis on dramatic contrasts of light and shade. More often than not, Claude's works were paeans to the beauty of nature rather than portrayals of grand human virtues - as was more common for painters of his style and generation - but they were nonetheless generally representations of historical or mythical scenes. At a time when landscape painting was still far from being considered a significant genre, he thus laid the foundations for the historical landscape tradition that would come to dominate French and English painting for at least 150 years.

The grand tour in the Colli Albani from the beginning to the eraly Twentieth Century
... The cultural views were diversified, with the coexistence of a romantic and sentimental concept of the landscape, with the neoclassical paysage historique of the French Academy, the variant of the Italian “historiated landscape”, the purism of the Nazarenes, but above all the adherence to the realism without hierarchy of subject, that is the objectivity applied to visual perception, promoted by English, French and then American painters. It was precisely this exchange of different ideas and visions that resulted in ever-changing critical contributions and profitable inputs for common growth.
... One of the first views of the area by an American artist is a historiated landscape by Robert Walter Weir (1803-1889), who stayed in Rome from 1825 to 1827, depicting The Duke of Bourbon’s Halt at La Riccia, on His March to the Assau Rome , May 3d, 1527, painted in New York in 1834 based on sketches or previous drawings, with an idealized but fairly faithful view of the village of Ariccia at sunset (Los Angeles County Museum of Art).
