Algorithm for designing a gothic spire (Roriczer) • • • If you want to draw a base plan for a pinnacle, according to the masons’ technique [derived] out of correct geometry, then begin by making a square as shown hereafter with the letters a b c d , so that it is the same distance from a to b as from b to d , d to c , and c to a , as in the figure drawn hereafter. Then make the square equal in size to the preceding; divide [the distance] from a to b into two equal parts, and mark an e [at the midpoint]. Do the same from b to d and mark an h ; from d to c and mark an f ; from c to a and mark a g . Then draw lines from e to h , h to f , f to g , and g to e , as in the example of the figure drawn hereafter. Then make the abovederived square equal in size to the preceding; divide [the side] from e to h into two equal parts, and mark a k [at the midpoint]. Do the same from h to f and mark an m ; from f to g and mark an l ; from g to e and mark an i . Then draw lines from e to h , h to f , f to g , and g to e , as in the example of the figure drawn hereafter. Then make the two squares a b c d and i k l m equal in size to the preceding, and rotate the square e h g f , as in the example of the figure drawn hereafter. • • • Then when you eliminate the remaining lines that are not needed for the setting out, there remains such a form as shown below. T he columns in each order ought to be form’d in ƒ uch a manner, that the diameter of the upper part of the column may be ƒ maller than at the bottom, with a kind of a...
