I believe they used a bone thumb ring to pull the bow string, using their left hand to hold the bow, with the ring on the right thumb holding the bow squeezed to the index. Supposedly releasing a single point of contact (bone ring) with the string increased the precision. The bow is also not quite right as it is a Kassar bow. The bow would have been more similar to a present-day Korean bow.
Nice picture
