Continuing on the theme of crossing the feet, here is an illustration from Fabris.
From the perspective of the sword, and the opponent, and the direction he is looking, the feet are crossed.
But wait you say, if you draw the center-line through the chest then it isn’t crossed. Fine:
The feet are crossed. No matter which direction you draw the line, the feet are crossed. So lets bury the “never cross your feet” precept in the same bone yard we tossed “never parry with the edge”.
