In 1918, Olga and Picasso got married. The young couple moved to an apartment that occupied two floors at 23 Rue La Boétie, acquired servants, a chauffeur, and began to move in different social circles, no doubt due to Olga’s influence. The chaotic get-togethers Picasso had with his artist friends gradually changed into formal receptions. Picasso’s image of himself changed as well, and this was reflected in the more conventional style he adopted in his art and the way in which he consciously made use of artistic traditions and ceased to be provocative. After cubism, Picasso returned to more traditional patterns -- if not exactly classical ones -- and this period is thus known as his Classicist period. A typical example of this new style is The Lovers. From time to time, he would return to cubism. His collaboration with the Ballet Russe went on: he worked on décor for “Le Tricorne” and drew portraits of the dancers. In 1920, he began to work on the décor for Stravinsky’s ballet Pulcinella. With the birth of his son Paul (Paolo) (1921), he returned to the Mother and Child theme again and again: Mother and Child.
In 1921, he painted his Cubist Three Musicians, in which he used a group of people as a cubist subject for the first time. The three figures are characters from the Italian Commedia dell’Arte (Pierrot, Harlequin and a monk). Though created after his Cubist period, the picture came to be regarded as a masterpiece of cubism. “Those who set out to explain a picture are setting out on the wrong foot. A short time ago Gertrude Stein elatedly informed me that at last she understood what my painting ‘Three Musicians’ represented. It was a still life!” wrote Picasso. In 1923, Picasso painted The Pipes of Pan, which is regarded as the most important work of his “classicist period”. Other interesting works include The Seated Harlequin and Women Running on the Beach. “Of all the misfortunes – hunger, misery, being misunderstood by the public – fame is by far the worst. This is how God chastises the artist. It is sad. It is true,” wrote Picasso
God had chastised Picasso. By the mid-twenties he became so popular that he “had to suffer a public that was gradually suppressing his individuality by blindly applauding every single picture he produced.” In addition to this, the artist was having marital problems. His wife Olga, a former ballet dancer, for whom the attention and admiration of the public was necessary, vital, and natural, could not understand Picasso's discomfort with his fame.
Picasso tried to preserve his independence by taking an interest in the unknown and the unfamiliar. He set up a sculptor’s studio near Paris and began to experiment with this new artistic medium. He produced a series of assemblies with a Guitar theme, using objects such as shirts, floor-rags, nails and string, as well as sculptures. In 1927, Picasso began an affair with seventeen-year old Marie-Thérèse Walter, his son Paolo's nurse. Much of his work after 1927 is fantastic and visionary in character. His Woman with Flower (1932) is a portrait of Marie-Thérèse, distorted and deformed in the manner of Surrealism. The Surrealism movement was growing in strength and popularity at the time, and even Picasso could not really avoid being influenced by this group of Parisian artists, although they, conversely, regarded him as their artistic stepfather.
“I keep doing my best not to lose sight of nature. I want to aim at similarity, a profound similarity which is more real than reality, thus becoming surrealist,” Picasso wrote. The worst time of his life, according to Picasso himself, began in June 1935. Marie-Thérèse was pregnant with his child, and his divorce from Olga had to be postponed again and again: their common wealth had become a target for lawyers. During this time of personal financial crisis, Picasso would add the bull, either dying or snorting furiously and threatening both man and animal alike, to his artistic arsenal. Being Spanish, Picasso had always been fascinated by bullfights, the so-called “tauromachia”. On October 5th of that year, his second child, a daughter, Maria de la Concepcion, called Maya, was born. In 1936, he met Dora Maar, a Yugoslavian photographer. Later, during the war, she became his constant companion. See Portrait of Dora.
