Here's a series of articles about the Spanish court etiquette at the court of Vienna. http://www.habsburger.net/en/chapter...rt?language=de
From the second article: The emperor "was due the tiefe Reverentz
or ‘Spanish reverence’: as a symbol of submission before His Imperial Majesty, courtiers made a deep bow on bended knee."
In the article on http://kops.ub.uni-konstanz.de/bitst...pdf?sequence=1
the author explains, similarily to what is explained on the other website, that there never was a fixed manual of court etiqutte but that there were experts who were trained for years in understanding the sense and function the etiquette had and to work out a ceremonial form for certain events.
Only after 1650 these ceremonial structures were written down into protocolls which were used by the experts then as a help to create a new ceremonial event.
This is a very interesting point as it shows the etiquette never was meant to be static, but to be adapted to changing situations.
So maybe you should go into more research how the author meant the situation to be for the king and then think up your own ceremony in order to convey what the author meant.
