Translation
We are three masters in guards with our spears, and they are based on those of the sword. And I am the first in Tutta Porta di Ferro (Full Iron Gate). I am placed to quickly beat the spear of the player, that is, I pass with the right foot and traverse off the line and in doing so, his spear will be beaten to the left. If I pass and beat in a single step, I will wound. This is something I cannot fail to do.
Explanation
Holding the spear vertically with the point up, the First Master waits in Posta Tutta Porta di Ferro to sweep and counter any incoming attack. The length of the spear means the sweep will cover the entire body in a single move, something like a sliding door, and can then smoothly rotate into a counter thrust, either high or low depending on circumstances.
Alternatively, the master can rotate the spear into Posta Vera Crose and make a relatively close range attack with a butt strike.
