The aesthetic value of these objects cannot be arrived at by reasoning. Familiarization is necessary. - Alexander Calder

It was more or less directly as a result of my visit to Piet Mondrian’s studio in 1930, and the sight of all his rectangles of color deployed on the wall, that my first work in the abstract was based on the concept of stellar relationships. Since then there have been variations from this theme, but I always seem to come back to it, in some form or other. For though the lightness of a pierced or serrated solid or surface is extremely interesting the still greater lack of weight of deployed nuclei is much more so.

Wherever there is a main issue the elimination of other things which are not essential will make for a stronger result. In the earlier static abstract sculptures I was most interested in space, vectoral quantities, and centers of differing densities.

As truly serious art must follow the greater laws, and not only appearances, I try to put all the elements in motion in my mobile sculptures.
