Note 101 — CHAP. II.
Thomas Taylor translation
The gnomons, from which square numbers are produced, are odd numbers in a natural series from unity, i. e. 1, 3, 5, 7, 9, 11, &c. for these, added to each other continually, produce square numbers ad infinitum. But these gnomons continually decrease from the highest, and are at length terminated by indivisible unity.
