4. Having determined the size of the hole, design the "scutula," termed
in Greek [Greek: peritretos],... holes in length and two and one sixth
in breadth. Bisect it by a line drawn diagonally from the angles, and
after this bisecting bring together the outlines of the figure so that
it may present a rhomboidal design, reducing it by one sixth of its
length and one fourth of its breadth at the (obtuse) angles. In the
part composed by the curvatures into which the points of the angles run
out, let the holes be situated, and let the breadth be reduced by one
sixth; moreover, let the hole be longer than it is broad by the
thickness of the bolt. After designing the scutula, let its outline be
worked down to give it a gentle curvature.
5. It should be given the thickness of seven twelfths of a hole. The
boxes are two holes (in height), one and three quarters in breadth, two
thirds of a hole in thickness except the part that is inserted in the
hole, and at the top one third of a hole in breadth. The sideposts are
five holes and two thirds in length, their curvature half a hole, and
their thickness thirty-seven forty-eighths of a hole. In the middle
their breadth is increased as much as it was near the hole in the
design, by the breadth and thickness of... hole; the height by one
fourth of a hole.
6. The (inner) strip on the "table" has a length of eight holes, a
breadth and thickness of half a hole. Its tenons are one hole and one
sixth long, and one quarter of a hole in thickness. The curvature of
this strip is three quarters of a hole. The outer strip has the same
breadth and thickness (as the inner), but the length is given by the
obtuse angle of the design and the breadth of the sidepost at its
curvature. The upper strips are to be equal to the lower; the
crosspiece
