How by nature obtained

The universal forces of nature, and the individual energies of the matter submitted to them, are so appointed and balanced, that they are continually bringing out curves of this kind in all visible forms, and that circular lines become nearly impossible under any circumstances. The gradual acceleration, for instance, of velocity, in streams that descend from hill-sides, as it gradually increases their power of erosion increases in the same gradual degree the rate of curvature in the descent of the slope, until at a certain degree of steepness this descent meets, and is concealed by the right line of the detritus. The junction of this right line with the plain is again modified by the farther bounding of the larger blocks, and by the successively diminishing proportion of landslips caused by erosion at the bottom, so that the whole line of the hill is one of curvature, first, gradually increasing in rapidity to the maximum steepness of which the particular rock is capable, and then decreasing in a decreasing ratio, until it arrives at the plain level. This type of form, modified of course more or less by the original boldness of the mountain, and dependent both on its age, its constituent rock, and the circumstances of its exposure, is yet in its general formula applicable to all. So the curves of all things in motion, and of all organic forms, most rudely and simply in the shell spirals, and in their most complicated development in the muscular lines of the higher animals. cheap oil paintings
This influence of apparent proportion, a proportion, be it observed, which has no reference to ultimate ends, but which is itself, seemingly, the end and object of operation in many of the forces of nature, is therefore at the root of all our delight in any beautiful form whatsoever. For no form can be beautiful which is not composed of curves whose unity is secured by relations of this kind. cheap oil painting
