Does anybody have any historical article or reference about the juggling technique we now call multiplex ?
Personally, my big reference about this topic is Sergeï Ignatov, the first I saw on TV when I started juggling, who threw several clubs at a time in a juggling pattern. Then, several jugglers and former students of CNAC extensively used this technique with clubs in the 1980-1990s. I can also think of the Gatto Multiplex within a 5 or 7 ball cascade.
Only starting a pattern by throwing several props at a time, then not using multiplex within the pattern, also counts in my opinion as a multiplex (i.e Kris Kremo with 3 balls), although I don’t think it expresses the same level of integration.
My intuition is that this technique could be a marker to help defining certain juggling historical periods : holding more than one prop in the same hand is / is not called juggling according to context.
Any other thoughts or info to share ?
