To quickly assess the difficulty of the text, read a short excerpt:
IO, structed on /?8 perpendicular to ay. Then imagine a cone whose base is the circle with the diameter /38, whose vertex is at a and its lateral boundaries are fta and a8 ; let ya be produced so that ad = ya, imagine the straight line By to be a scale-beam with its center at a and in the semi-circle fia.8 draw a straight line £0 1 1 (38 ; let it cut the circumference of the semicircle in | and o, the lateral boundaries of the cone in ir and p, and ay in c . On |o construct a plane perpen- dicu...lar to ae; it will intersect the hemisphere in a circle with the diameter £0, and the cone in a circle with the diameter m. Now because ay.ae = & 2 : ae 2 and £a 2 = ae 2 + e£ 2 and ae = ew, therefore ay : ae = £e 2 + en 2 : eTr 2 . But $e 2 + €ir 2 :€Tr 2 -the circle with the diameter £0 + the circle with the diameter irp : the circle with the diameter wp, and ya = a0, hence 6a : ae = the circle with the diameter |o + the circle with the diameter np : circle with the diameter irp. Therefore the two circles whose diameters are £0 and irp in their present position are in equilibrium at the point a with the circle whose diameter is wp if it is transferred and so arranged at 6 that 6 is its center of gravity.
