Where the Italians and after them the French, Germans and English gradually discovered that simplification led to perfection, the Spanish masters, in his account, aimed at making fencing a more and more mysterious science, requiring for its practice a knowledge of geometry and natural philosophy.", "sources": [ "castle-schools-and-masters-of-fence-1885" ], "confidence": 0.9 }, { "id": "c4", "text": "The geometry was not decorative; it was the measuring instrument.

The opponents stand at opposite ends of its diameter, whose length is regulated by the effective length of the arm, with the sword extended horizontally; tangent to the circle at the opposite ends of that diameter are imagined two parallel lines called infinite, \"lineas infinitas\", for the reason that both adversaries might travel along them for ever without altering anything.", "sources": [ "castle-schools-and-masters-of-fence-1885" ], "confidence": 0.85 }, { "id": "c5", "text": "The same geometry appears in the primary, in the author's own vocabulary and applied to the hardest concept in the doctrine.

The lines are then derived: from the curve come the flexuous and the spiral, \"que es la que va rodeando a manera de caracol\", and the heliacal, \"que es la que va ciñendo algun cuerpo\"; from the straight line come the parallels, the perpendicular, the diagonal, the hypotenuse and the diametral; and from the angular posture come all the species of wounds.", "sources": [ "pacheco-de-narvaez-compendio-de-la-filosofia-1612" ], "confidence": 0.85 }, { "id": "c6", "text": "The claim that made this a public science rather than a trade secret is printed on the title of the companion work, and the critic quotes it without noticing what it means.
