- It is just the same with the quadrature of the circle. - "The Exemplary Novels of Cervantes", Miguel de Cervantes Saavedra.
- On the Quadrature of the Circle, he says he cannot decide if this problem be resolvable or not: but he observes, that it is very useless to search for it any more; since we have arrived by approximation to such a point of accuracy, that on a large circle, such as the orbit which the earth describes round the sun, the geometrician will not mistake by the thickness of a hair. - "Curiosities of Literature, Vol. 1 (of 3)", Isaac D'Israeli.
- The quadrature of the circle is still, however, a favourite game with some visionaries, and several are still imagining that they have discovered the perpetual motion; the Italians nickname them matto perpetuo: and Bekker tells us of the fate of one Hartmann, of Leipsic, who was in such despair at having passed his life so vainly, in studying the perpetual motion, that at length he hanged himself! - "Curiosities of Literature, Vol. 1 (of 3)", Isaac D'Israeli.
