The author planned by means of a mimicry and gestures to reflect character of the emperor, but this variant has been rejected of Monferran's for the reason that could not serve the primary purpose of association of spatial ensembles. Klodt has created the new sketch in which it has represented a horse in the movement, leaning only on back pair feet.
