Lenard does not refer to any figures connected with a branch called art

Lenard's Ferronneria is full of fantastic pieces. My Polish is lacking, so we'll rely on what he says about his work:

La Ferronneria that is Machinecreating. This is a third generation of retransformed machineries known from somewhere else. These subjects have a fictitious function and their author endows them with a compulsive-obsessive syndrome. These mechanisms are made of nobly ageing metal with a discreet contribution of mirrors, electric current, and with intangible participation of models stylized in a retro way.

The whole art is influenced by Hertz formulas, Brewster angle, Kardan shafts, Oldham clutch, Junghans watches and other great creators. Spiritual patronage is exercised by rabbi Löwa ben Becalel. However, the author does not refer to any figures connected with a branch called art.
