Much of this text comes across as a reasoned stream of thought about Rossi's opinions on how fencing should be taught, however there are a few very interesting insights into the benefits of the Radaellian molinelli and Rossi's pedagogical method for turning the wide practice molinelli into faster, "restricted" molinelli:
The molinelli with wide rotation are very useful because, in addition to the aforementioned benefits, with them one obtains the actions that are performed in the bout; for example: if we from guard of second parry third and riposte to the opponent’s inside flank, we perform the traversone with the exercise molinello. So too if we from guard of second parry first and riposte, we have performed the molinello with wide rotation.
The molinello that serves to touch the opponent is certainly not that which one does in the beginning of teaching, when the maestro sees the ease in executing the molinello with wide rotation he must, with graduated lessons, oblige the student to quickly move the blade away by means of a sforzo, and he must use a few blows in tempo to the arm in order to make him increase the promptness in the final part of the molinello such that a little bit from the sforzo, a little bit from the blow in tempo to the arm, the student will be obliged to restrict his molinello in order to avoid the possibility of the blow to the arm in the execution of the molinello.
In addition to the technical aspects, Rossi also spends a decent amount of time talking about the role of the instructor in shaping the fencer's instincts and morale:
Now there is no doubt that he who will be morally stronger, and yet more confident in the outcome is the one who, being worried about the consequences of the clash, will know how to keep his cold blood unperturbed in every moment of the action.
Now, if the one who succeeded in putting his opponent in a parry is perfected in the mechanical part, at equal speeds he is certain to touch.
Otherwise his advantages will pass to his opponent, because in order to have parried, he is found in an advantageous position and a contrast of parries and ripostes will occur, with equal mechanical strength victory will be with the one with greater intellect. As shown in this bout I would be able to cite a hundred other combinations in which the fencer’s morale and intellect are due to the mechanical part studied in the instinctive effects of man.
This, I feel, is an excellent illustration of Italian fencing, with all its fiery yet calculated fervour.
