The point is, that the agent was considered internal, it was still considered true PM [at the time] - Bessler included it in his book in the section headed "To Those Who Do Not Believe" - i.e. do not believe in the possibility of PM, so he must have considered/believed it true PM.
I'm not sure about whether Bogehold is telling Bessler to be less vague but more of an admission that he & others didn't fully understand Drebbel's engine - he takes a bob each way by saying it might be true PM or involve some trickery - he bangs on about squaring the circle as a deflection, a more worthy pursuit than PM for great minds, though hardly has greater implications - Bessler includes the squaring the circle geometry in his wheel pictures as a reminder that he is amongst the elite class of thinkers & achievers & deserving to be there - there may be additional geometry involved revealed from the squaring process in the pictures.
Bessler obviously thought any engine [ever lasting motion machine] that used either internal or external agents that didn't need to be physically replenished with fuel [input energy] brought to it constituted true PM & that's why he included it in his book - the interesting thing is he never actually said so out loud, so to speak - scared to open that can of worms perhaps ?

After Drebbel’s letter which is inside Valentinus letter, he says this about Drebbel:
When I read this Fletcher is he not actually telling Bessler not to ride the grey area and be clear where perpetual motion is coming from?Hence I shall give a warning to all lovers of this art, and demonstrate to them a better way.
As far as Drebelius is concerned, it seems to me that we cannot
be sure quite what he had in mind; whether he wished to keep
some things from becoming common knowledge, or even
conceal some of them from the KING himself. And, despite
much searching among the writings of industrious scholars, I do
not know whether in truth he really discovered and perfected the art of PERPETUAL MOTION; this must remain uncertain to us.
Nevertheless, His High Eminence Cardinal Perronius, once listed, amongst the store of lost inventions, these six which, he said, clever men might wish to investigate; viz: -
1) The Squaring of the Circle,
2) The Doubling of the Cube,
3) The Preparation of the Philosopher’s Stone,
4) Divination through Astrology,
5) Magic and
6) Perpetual Motion.

After the above quote, Valentinus goes on for pages on The Squaring of the Circle... why?

This post from Mr Tim's thread some time ago > General Discussion > PM found in 1612

Quote:
(...) You mention looking up Drebbel in the book. Unfortunately the references to him are incomplete and inaccurate. The first reference on page 95, about his claims for perpetual motion, are compliled from his patent of 1597 and his letter to James when he wanted out of Prague in 1613. The patent is misquoted in that he never said "1000 years", but actually up to 100 years, if the clockwork did not wear out:
"Ende t'ander een horelogie oft uuyrwyser twelcken den tijt van vijftich, LX, jae hondert oft meer jaeren achter den anderen sal mogen gebruycken, sonder opwinden oft yet anders daertoe te doen, soo lange de raden oft 't ander gaende werck niet versleten en zijn".
You can see the part, "fifty, sixty, nay, one hundred years..."
I could be wrong, but I never came across "a thousand". But the important point is not the time he claimed, but what passed as perpetual motion at the time.
If a machine operated off natural and permanent sources of heat,
temperature, air pressure, etc., then it was "perpetual", and was not
classified differently than the impossible version, with no outside power.
Curiously, I ran across the same problem with my youtube video of his
device, when several watchers chastised me for calling it such... that it
was thermodynamic, etc. They did not read the discription I included, which explains this. So today, as in the time of Carrington's book, such a claim is treated with dirision, when the modern definition is wrongly applied.
