A hood is an article of clothing, a covering for the head; it differs from the hat in that it completely encloses the head. The most common form in period armory seems to be the “monk’s hood”, as in the civic arms of Güglingen, 1605 [Siebmacher 226].
Varieties unique to Society heraldry include the “jester’s hood”, with a forked top and bells; the “executioner’s hood”, which covers the face as well; and the “teaching master’s hood”, with a long tasseled end.
