In the context of Les Demoiselles d'Avignon, discuss the El Greco of the Influences.

In 1907, when Picasso began work on Les Demoiselles, one of the old master painters he greatly admired was El Greco (1541–1614), who at the time was largely obscure and under-appreciated. Picasso's friend Ignacio Zuloaga (1870–1945) acquired El Greco's masterpiece, the Opening of the Fifth Seal, in 1897 for 1000 pesetas. The relation between Les Demoiselles d'Avignon and the Opening of the Fifth Seal was pinpointed in the early 1980s, when the stylistic similarities and the relationship between the motifs and visually identifying qualities of both works were analyzed.El Greco's painting, which Picasso studied repeatedly in Zuloaga's house, inspired not only the size, format, and composition of Les Demoiselles d'Avignon, but also its apocalyptic power. Later, speaking of the work to Dor de la Souchère in Antibes, Picasso said: "In any case, only the execution counts. From this point of view, it is correct to say that Cubism has a Spanish origin and that I invented Cubism. We must look for the Spanish influence in Cézanne. Things themselves necessitate it, the influence of El Greco, a Venetian painter, on him. But his structure is Cubist."The relationship of the painting to other group portraits in the Western tradition, such as Diana and Callisto by Titian (1488–1576), and the same subject by Rubens (1577–1640), in the Prado, has also been discussed.
