This section depicts the coats of arms of several Popes of the modern era. In addition, the first few examples, concerning the arms of Pope Benedict XVI, illustrate how heraldic designs do not have to be slavishly copied. Rather, different artists will render the same coat of arms in different ways depending on their own style. The science of heraldry may dictate that the elements of the design be repeated in a particular way over and over. The art of heraldry allows great freedom and variety of expression.
