A continental view...
Here is another faux historical piece about Parasol Duelling.
Written by the talented Stewart MacPhee of Calgary, it is a very interesting look at one of the many continental styles of Parasol Duelling that could have existed at the time of Queen Victoria.
Keep your sightglass full, your fire box trimmed and your water iced.
Ed: This evening, continuing the fascinating discussions on Parasol Duelling, I am happy to post a paper from a more European and Continental perspective.
This paper, by a Dr. Johann Portsmouth Adler, appears to have been written shortly after the time that the Brandenburg Variations were formalized by Her Majesty. It discusses the version of Parasol Duelling as practiced in Prussia at that time. The contrasts with the Queen's Rules are intriguing.
I am hoping to get more information on the specific provenance of this paper, but even without the details of its source there is much here that warrants close study.
Ed: This is all that remains of Dr Adler's paper one wonders what else he may have discussed, alas no other pages have been preserved.
