Publisher's Synopsis
Gazing at the heavens on a starry night, we see, in addition to myriads of sparkling worlds floating in the air, a great quantity of nebulae-either decayed systems of worlds, or worlds in formation. Worlds which have lost their centre of gravity and fallen to pieces; or worlds which are seeking, according to the general law of gravitation, to form a central body by the attraction of cosmical ether. The one phenomenon is that of destruction, the other that of new formation. This double process is continually repeating itself in the development of art. Consciously or unconsciously, the artists of the different nations, at different periods, devote themselves to the dissolution or reconstruction of artistic products. To become acquainted with this process, to trace the elements from which art is built up, or the influences which engender a dissolution of artistic forms, is of the greatest importance."
