Trust Me, I'm an Artist
From Waag
The performance Que le cheval vive en moi (May the horse 
live in me) is an extreme, medical self-experiment with a 
blood-brotherhood beyond species boundaries. With this performance, the 
French duo Art Orienté objet calls for greater ecological 
responsibility from humans, whose technologies increasingly 
instrumentalize other animals and plants. The artist Marion 
Laval-Jeantet has turned herself into a proverbial “guinea pig,” 
allowing herself to be injected over the course of several months with 
horse immunoglobulins (glycoproteins that function as antibodies in 
immune response) and thus developing a progressive tolerance to these 
foreign animal bodies.
In February 2011, having built up her tolerance, she was able to be 
injected with horse blood plasma containing the entire spectrum of 
foreign immunoglobulins, without falling into anaphylactic shock—the 
intention being that the horse immunoglobulin would by-pass the 
defensive mechanisms of her own human immune system, enter her blood 
stream to bond with the proteins of her own body and, as a result of 
this synthesis, have an effect on all major body functions. 
Immunoglobulins are biochemical messengers that control, for example, 
the glands and organs of the endocrine system, which is also closely 
tied to the nervous system, so that the artist, during and in the weeks 
after the performance, experienced not only alterations in her 
physiological rhythm but also of her consciousness, characterized by 
heightened sensibility and nervousness....MORE

precautions to build up her immune system). after the transfusion, the

prosthetic horse-like stilts before her hybrid blood was extracted and
