A spur is a pointed piece of metal worn on a rider’s heel to urge the horse forward. The default form of spur is the roweled spur, with a six-pointed mullet attached to a U-shaped frame and buckle. It’s a period charge, found in the canting arms (Italian sperone) of Speroni, c.1555 [BSB Cod.Icon 275:65], and as the crest of Matela, c.1540 [Nobreza xxixº].
In mundane armory, the spur is frequently drawn with leather straps; in Society armory, these are left to the artist’s license. While some sources give the spur’s default orientation as having the rowel to base, the majority [Franklyn 312; Guide 215] put the rowel to chief, and this is the Society’s default for the spur as well.
Society armory also has the “prickspur”, which has no rowel, but simply comes to a point. Its default orientation is the same as for the roweled spur, with the point to chief, and no difference is counted between the types. See also stirrup.
