 Nicolaus of Cusa: Quadrature of the Circle 
  A segment that is cut off from a circle by a straight line cannot, in respect to its incidental angles, which are parts of its surface, be transformed into a rectilinearly enclosed figure; therefore also not in respect to its totality. 
  If therefore this length is extended, in the proportion of the segment lying between the endpoint on eb and the point e to the length ab, or in the proportion of the segment lying between the endpoint on eb and b to the length ab, it remains always proportional. 
  Proceeding still farther, we observe the diversity of circles, and that only one can be the largest, the circle in perfected reality, the selfsubsisting, eternal and infinite, to which one cannot ascend through ever so many circles, since, in things that admit of larger and smaller, one cannot come to the simply maximum.
