"How should one approach the person of van Gogh in order to be able to build a statue of him? How can one place him outside of himself, separate him from the tragic character of his life? How can one build a statue in the open air which simultaneously evokes the rare and the new person who was van Gogh, as also the enormity of the new aspect of the current and future art of painting?"

“Were I to concentrate exclusively on the body of Prometheus, I would be seriously limiting the scope of my rendering of the demigod; but because I concentrate also on the myth of Prometheus, on all that the great poets have written about him, I expand the meaning of the demigod's physical form and try to communicate.. ..the basic message of the legend of Prometheus, who stole fire from the gods and taught man to cook his foods, to smelt metal ore and to forge his tools and weapons.”

“In my own researches and findings I have always insisted on plastic and sculptural values, and also on what I call a poetic climate. The object, whether it is a book, a bottle, or a human body, once it is visualized and expressed by means of clay, stone, or wood, ceases to be a document and becomes an animated object in stone, wood, or bronze and lives its independent life..”

“In every human being, there are dormant memories which suddenly rise to the surface of the conscious mind. Niobe, for instance, developed out of one of my most remote childhood recollections. A cholera epidemic had broken out in the Smolensk area, and there were many casualties. One day, on the top of a hill, I saw a giant of a peasant with arms raised toward the sky crying out his grief at having lost his children. From this image, which emerged from my subconscious mind many years later, came the statue of Niobe.”

“But a sculpture which sets out to achieve the same ends demands an almost unbelievable effort of concentration. Practically none of the episodes or moments of such a legend, really lends itself to sculpture, and the sculptors of the nineteenth century were often quite careless or foolish in the choice of the moment which they set out to represent. Their works could thus become cluttered with all sorts of narrative details which detract from the monumental quality of the whole.. .That's why, in my 'Prometheus', I represent the fire as an integral part of the presence or appearance of the hero; he stands there before us in all his awe-inspiring grandeur, a human figure that seemed in the eyes of the men who first saw him to be actually consumed by the fire that he was bearing.”

“I do not believe that art must develop on national lines, but I am convinced that there never was and never will be an international art. There is and was French, German, Italian, and Flemish art. But I deny those specific definitions so fashionable with adepts of fascism which make of every country an hermetic cell from which all foreign artists are excluded.”

“In October 1945 I returned from America, where I had stayed during the war. I arrived in Le Havre, full of ruins, a carcass of a city. It took one night to reach Paris on a train with no windows. That night I got the idea for the monument. I sketched it on paper and forgot about it, until I visited Rotterdam for the first time in 1947. I saw a city without a heart. I saw a crater in the body of a city. And I remembered that night, the sketches. I made a small terracotta model and sent it to an exhibition of French art in Germany.”
