A spinning wheel is a tool for making thread; it is sometimes termed a “wool wheel”. It has a large wheel turning a single spindle, on which the thread is spun; period wheels were turned by hand, not by a foot treadle. Though a period artifact, the spinning wheel has not been found in period armory. The illustration is taken from the Luttrell Psalter, c.1340; it is the earliest known depiction of the artifact.
