Horse Ball is a direct heir to PATO (national sport of Argentina, played on horseback).
This being the reason that the first Horse Ball trials were played using a Pato ball, Pato goals, Pato priority rules, and the same pick-up technique (in the early years the stirrups were not joined together with a strap!).
We now know thanks to some old evidence that the arrival of Pato in France dates back to Captain CLAVE, champion show-jumper in the 1930s.
The matches took place during Horse Shows and were played between different military regiments. The war started and Horse Ball disappeared, being practised only by a few riding instructors in their clubs as exercises for improving the ‘seat’.
Pato came to life again not long after the war, being presented regularly in its Argentinean form, by celebrity stuntman Mario LURASHI.
