4. A Spheare is made by the conversion of a semicircle, the diameter standing still. 14 d xj.
As here thou seest.
5. The greatest circle of a spheare, is that which cutteth the spheare into two equall parts.
Therefore
6. That circle which is neerest to the greatest, is greater than that which is farther off.
And
7. Those which are equally distant from the greatest are equall.
As in the example above written.
