VERTICILL'US. The whorl or whirl of a spindle (Plin. H. N. xxxvii. 11. § 1.); which consisted of a small circular wheel or plate of wood, stone, or metal, through which the lower end of the spindle (fusus) was inserted, for the purpose of giving it rotation, and assisting by its weight to twist the thread tight. It is seen on the bottom part of the annexed wood-cuts (Verticillus/1.1), representing an original Egyptian spindle, on one side enveloped in the spun thread, and simply by itself on the other.
