What is the origin of spangle?

The verb spangle, to decorate with any small, bright drops, objects, spots, or the like,” comes from the noun spangle, “a small, thin piece of glittering metal used for decorating cloths” or “a small, bright object or spot” (such as one of the stars on the Star-Spangled Banner), which is formed from the noun spang “a small, glittering ornament” and the diminutive suffix –le, as in bramble or thimble. Spang may come either from Middle Dutch spange, spaenge “brooch, clasp” or from Old Norse spǫng “clasp, buckle, spangle.” Spangle entered English in the first half of the 15th century.
