Clergy often refrain from displaying a helm or crest in their heraldic achievements. Members of the clergy may display appropriate headwear. This often takes the form of a small crowned, wide brimmed hat called a galero with the colours and tassels denoting rank; or, in the case of Papal coats of arms until the inauguration of Pope Benedict XVI in 2005, an elaborate triple crown known as a tiara. Benedict broke with tradition to substitute a mitre in his arms. Orthodox and Presbyterian clergy do sometimes adopt other forms of head gear to ensign their shields. In the Anglican tradition, clergy members may pass crests on to their offspring, but rarely display them on their own shields.
