Peter Hoffmann has released a practical publication dedicated to the "Porte les Bras". It is visually attractive and contains many historical engravings showing the right "Porte de Bras". Many sources are cited. I think it is worth to take a look at.
A second part is annouced for the end of 2008. It will cover the "Haute Porte de Bras".
It is written in German and can be downloaded at http://www.barocktanz.com/literatur-2.html
