An icicle is a spike of ice, formed when water dripping from a roof freezes. The charge is period, found in the arms of Herbotell or Harbottle, c.1295 [ANA2 477], but the name “icicle” may not be: texts have suggested that they might be “hair bottles”, or possibly “gouts inverted”. In any event, the charge seems confined to the arms of this family. The icicle is palewise, point to base by default.
