These guys are at it again: Interesting that they included the "three turns of the sword" which Fiore mentions but never defines. I think that their interpretation is likely correct, and makes sense. Fiore defines the three turns of the body in detail, and only mentions that the sword likewise has three turns. I've always admired Fiore's system. It's simple, elegant, and beautiful to watch. It's also complete in one manual showing many weapons by one master. The contemporary German school (my HEMA system of choice) is spread out over multiple masters, but is vast. Joachim Meyer's manual (also a complete system) was from 150 years later.
