Hello Jon,
I proposed that Ch.5, note 4, of Silver's BIofPod is ALL about distance & footwork, specifically that 'double' and 'false' can be references to footwork, simply because it's possible to interpret them as such. That's the nature of Silver's work, account his broad application of terminilogies.
Silver defines 'false times' in Ch.18 of PoD rather broadly :
The false times are these:
The time of the foot,
the time of the foot and body,
the time of the foot, body, and hand, (and)
the time of the feet, body, and hand.
Take your pick.
I can't find his definition of 'double', so it could be interpreted as referring to a specific footwork step, a double strike, or even a specific type of disengage. Again, take your pick.
As far as a 'ward' being his terminilogy for a specific parry or parrying riposte, I don't see this as precluding the text cited as being an example starting out of distance, as far as I understand the following excerpt from Ch.4 of PoD:
For they verily think that he that first thrusts is in great danger of his life, therefore with all speed do they put themselves in ward, or Stocata, the surest guard of all other, as Vincentio says, and thereupon they stand sure, saying the one to the other, "thrust if you dare", and says the other, "thrust if you dare", or "strike or thrust if you dare", says the other. Then says the other, "strike or thrust if you dare, for your life". These two cunning gentlemen standing along time together, upon this worthy ward, they both depart in peace, according to the old proverb: "It is good sleeping in a whole skin."
'Stocata' is defined as a variable fight in Ch.4 of BIofPoD. His 'variable fight' is defined in Ch.11 of PoD.
And I notice that note 4 of Ch.5 of BIofPoD, if looked upon as a situational example of footwork, would be interestingly echoed in the 3rd paragraph of Ch.16 of BIofPoDs:
Upon this ground some shallow witted fellow may say, if the patient must keep large distance, then he must be driven to go back still, to which I answer that in the continual motion & traverses of his ground he is to traverse circularly, forewards, backwards, upon the right hand,& upon the left hand, the which traverses are a certainty to be used within himself, & not to be prevented by the agent, because the agent comes one upon a certain mark, for when he thinks to be sure of his purpose, he patient is sometimes on the one side, & sometimes on the other side, sometimes too far back, & sometimes too near, so still the agent must use the number of his feet which will be too long to answer the hand of the patient agent, & it cannot be denied but (that) the patient agent by reason of his large distance, still sees what the agent does in his coming (in), but the agent cannot see what the other (will) do, 'til the patient agent be into his action, therefore too late for him either to hurt the patient, or in due time to defend himself, because he entered into his action upon the knowledge of the patient, be he knows not what the patient agent will do 'til it is to late.
As far as food for thought goes, one would never starve with a copy of Silver's text.
