The rhinoceros is a ponderous beast, slow to anger, and famed for its hide’s inpenetrability. It’s a period charge, found as the crest of William Wade, 1574 [Woodcock & Robinson, Heraldry in Historic Houses of Britain, p.163], and as the crest of the Worshipful Company of Apothecaries, 1617 [Bromley & Child 1-3]. The period heraldic examples seem to be directly based on a woodcut by Albrecht Dürer, 1515 – as is the illustration. The rhinoceros is statant by default.
