The goat is a horned, hooved beast famed for its lasciviousness (and, strangely enough, its eyesight). The most common depiction is long-horned and bearded, with longer hair at the throat. It’s a common charge, found as early as c.1320, in the arms of Obaerloh or Obaerlon [Zurich 366].
Special terms applied to goats include “clymant”, meaning rampant. The goat doesn’t seem to have any default posture; the illustration shows a goat clymant. For related charges, see ibex (natural), musimon, sheep.
