In the back of Meyer’s 1560 manual there is a set of curious diagrams. They don’t seem to be explained anywhere, but have the appearance of cutting diagrams.
Our theory is that each number that is preceded by a circle indicates a thrust originating from that quadrant.
This theory assumes that there are some stray marks and mistakes in the diagrams, which we believe is feasible given that this is a manuscript rather than a heavily edited and printed text. That said, there are numerous features that we need to explain.
Lines 1 and 2 are very steep, cutting from the knee through the face. I see this as analogous to Fiore’s rising cuts.
Cut #1 is to the thigh. Given that it is only a half-cut, it is probably a low feint followed by the real attack from above.
Again, we see a rising cut that is intend as a feint to draw the parry away from the real attack.
These two employ both high and low horizontal cuts.
