I have read descriptions of how they could shoot from under or over their pony's neck as they hung from its side.
I only know they tied a loop in the mane to hang from and kept one heel over the spine of the horse. But where is the other leg? Is there a stirrup of some kind? Did they brace it against the stifle of the back leg as a kind of foot-hold?
If you have any resource on this at all, please let me know!
