Bull

eccles. law. A letter from the pope of Rome, written on parchment, to which is attached a leaden seal, impressed with the images of Saint Peter and Saint Paul. There are three kinds of apostolical rescripts, the brief, the signature, and the bull, which is most commonly used in legal matters. Bulls may be compared to the edicts and letters-patent of secular princes: when the bull grants a favour the seal is attached by means of silken strings, and when to direct execution to be performed, with flax cords. They are written in latin in a round and gothic hand.
