 Even though Lamoureux depicted the horse in a trot-like gait, with inspiration from Marcus Aurelius' horse at the Capitoline Hill, the design caused severe problems due to the soft metal used for the casting.The construction therefore had to be strengthened, and Lamoureux introduced a figure of a naked man crouched underneath the horse's hoof, personifying envy but in the same time affording support for the horse's barrel as the weakest point of the statue.However, over the centuries the problems with the statue continued, particularly with the horse's front left leg, and finally Professor Einar Utzon-Frank from the Danish Academy of Fine Arts was commissioned to recast the statue in bronze.
