In 1981, Ganimedes was acquired by Romanian-born dressage trainer George Theodorescu as a future prospect for his daughter Monica.
The pair helped the German team to a gold medal, and were also in contention for an individual honor, having placed third in the opening round.
The mistakes were largely attributed to a wandering shadow coming from a roof of the Grand Stand, which spooked at least six horses during the competition.
Grunox went on to be Theodorescu's pick for the Barcelona Olympics, while Ganimedes' competition career from that point on was mostly focused on the World Cup.
