Having observed that the equestrian figures on the Great Seals of most of our kings and ancient barons from the Conquest to the time of Edward III. are represented with spurs consisting of only one point, somewhat resembling the gassle with which fighting cocks are armed, I have endeavoured to trace out the origin of these spurs, which appear to have been worn after the invention of the rouelle, or wheel spur (so called from the revolution of its spicula about an axis), several of our kings and great barons being on different seals sometimes represented with one, and sometimes with the other species.
