I'm studying the I:33 Sword & Buckler manual using Blender. I came across a website which had 2d flow charts with original pictures and modern graphics showing foot and sword movement. I figured that a 3d interpretation would be even better. The pictures above are proof of concept. 3d allows viewing the action from various angles, and could add clarity to the path of the sword, and stepping. Even clearer once I animate it. What I like best about a CG interpretation is that I can correct my mistakes quickly. This isn't as easy with live video. Take my interpretation with a grain of salt. I am a student, not a master.
The technique shown above is known as falling under the sword. It is illustrated by a Priest, on the left, and a Scholar. The Priest starts with the sword under his arm, in 1st ward. He brings his sword out to bind with the Scholar's. The Scholar's position is a counter known as Half Shield. Having fallen under the sword, the Priest can enter.
The orginal Latin text is:
Custodia prima retinet contraria bina,
Contrarium primum halpschil langortque secundum,
Dum ducitur halpschilt cade sub gladium quoque scutum,
Si autem uis edoceri consilio sacerdotis tunc religa et calca.
Which translates to:
The first ward has two counters,
The first counter being Half Shield, the second Long Point,
If Half Shield is executed, fall below both sword and shield,
But if you would be instructed by the priest's counsel, do bind and enter.
The I:33 goes on to explain other options for the Priest, and counters for the Scholar.
