"In 1923, the delicate nuances of ancient works are counterbalanced in his cubist paintings with a fireworks display that resembles a final bouquet. The Birdcage is fragmented into small colorful frames that culminate in regular peaks, bright against a dark background or vice versa.

The window bars, the branch, the bird are stylized like in folk embroideries. The whole composition has a strange folkloric style. It is vivid like in peoples with rich imagination. These echoes of folklore often awaken in Picasso's art as if he has roots everywhere where people have vividly dreamed."
