After this the potro came in play. The patient was released from the trampa and mancuerda and placed on the eleven sharp rungs of the potro, his ankles rigidly tied to the sides and his head sinking into a depression where it was held immovable by a cord across the forehead. The belt was loosened so that it would slip around. Three cords were passed around each upper arm, the ends being carried into rings on the sides of the potro and furnished with garrotes or sticks to twist them tight; two similar ones were put on each thigh and one on each calf, making twelve in all. The ends were carried to a _maestra garrote_ by which the executioner could control all at once. These worked not only by compression but by travelling around the limbs, carrying away skin and flesh. Each half round was reckoned a _vuelta_ or turn, six or seven of which was the maximum, but it was usual not to exceed five, even with strong men. Formerly the same was done with the cord around the forehead, but this was abandoned as it was apt to start the eyes from their sockets. All this, the Cordova tribunal concludes, is very violent, but it is less so and less dangerous than the abandoned methods. These remained practically the tortures in use. In 1662 the Suprema, in ordering the tribunal of Galicia to "continue" the torture of Antonio Méndez, called upon it to report as to its manner of administering torture. Its answer of May 13th shows that it was using the mancuerda and potro, though after a somewhat primitive fashion. To this, by order of the Suprema, Gonzalo Bravo replied, May 22d with elaborate instructions, especially as to the trampazo, indicating that substantially the methods described by Córdova were recognized officially. Galicia appears to have puzzled over this until September 19th, when it apologized for its lack of experience and asked for detailed plans and drawings of the form of potro required. It is fairly presumable from all this that thenceforward these new methods were adopted in all the tribunals.[65] * * * * * [Sidenote: _SEVERITY_]
