Turned Fourth against another passing Fourth

This following figure is a turned Fourth (quarta girata) which wounds against another Fourth passed with the left foot. It happens because the one who has passed makes a feint of wanting to wound on the outside above the sword, and the other goes to parry. The first places the left hand to the enemy sword on the inside in order to parry, and in that same time disengages in Fourth on the inside, passing beyond with the left foot in order to wound with that Fourth. But the other, who had gone to defend against the outside feint, seeing that the enemy wished to defend with the left hand, disengages the sword that had been above by the outside of that hand and puts it into the body of the enemy who was coming on; and by turning with the left foot he carries himself out of presence.

He would not have gone to wound so low with the point had it not been for finding with his own forte the enemy weak, in order to remain more secure. Thus the hand that thought it would parry is deceived, as one sees. This is one of Fabris' clearest demonstrations that hand-parries are not to be trusted simply because they seem to intercept the direct line; they can be passed around and made to create the very opening they hoped to close.
