Came across an abstract of an dissertation entitled "The artist as 'magician' and 'alchemist' between production and perception, Occult traditions in European art history after 1945, A comparative research study- beginning with Joseph Beuys" by Verena Kuni
Joseph Beuys; Rebecca Horn; Anselm Kiefer; Sigmar Polke; Marina Abramovic; Matthew Barney; Anna Blume; Bernhard Johannes Blume; Sylvie Fleury; Yves Klein; Jonathan Meese; Mariko Mori; Hermann Nitsch; Vettor Pisani; Ulrike Rosenbach; Niki de Saint Phalle; Daniel Spoerri; Gilberto Zorio a. o.
I will link these as I check them out...
The original dissertation is in German, so I'm hunting for a translation - I might have to use google translate which is bound to give some comic results...
The english abstract is here
