science that studies the movements of horses by comparing them to
the mechanics of an engine, was considered long ago, by the two famous
Muybridge and Etienne
Jules Marey at the end of the 18th century. Their approach was
mathemathical, more precisely, they applied analytic geometry to the
study of movement. Their images were strange joints between elementary
geometry and organic forms - bodies.
instead, does not so much consider the acting subject (a horse, a
bird or a man) but underlines the importance of the stroboscopic line
drawn by a body in motion - through the (in)visibility of its speed.
