Phalaris's bull, or the Brazen Bull, was a bull of cast metal, found in Sicily, and supposed to have been used by Phalaris to enclose and burn such as he chose to punish--a very unlikely species of cruelty. The bulls of Medea guarded the Golden Fleece. The bull of Marathon was tamed by Hercules. Then there were the bull which carried off Europa, the bull of Mithras, and the bull of Osiris; there are the Bull, a sign of the zodiac, and the Bull's Eye, a star of the first magnitude, and lastly, there are bull-fights, common in Spain. BULL (PAPAL). This word designates the bull, or seal of gold, silver, wax, or lead, attached to any instrument or charter. The lead hanging to the rescripts despatched in the Roman court bears on one side the head of St. Peter on the right, and that of St. Paul on the left; and, on the reverse, the name of the reigning pope, with the year of his pontificate. The bull is written on parchment. In the greeting, the pope takes no title but that of "Servant of the Servants of God," according to the holy words of Jesus to His Disciples--"Whosoever will be chief among you, let him be your servant." Some heretics assert that, by this formula, humble in appearance, the popes mean to express a sort of feudal system, of which God is chief; whose high vassals, Peter and Paul, are represented by their servant the pontiff; while the lesser vassals are all secular princes, whether emperors, kings, or dukes. They doubtless found this assertion on the famous bull _In cœna Domini,_ which is publicly read at Rome by a cardinal-deacon every year, on Holy Thursday, in the presence of the pope, attended by the rest of the cardinals and bishops. After the ceremony, his holiness casts a lighted torch into the public square in token of anathema. This bull is, to be found in Tome i., p. 714 of the _Bullaire_, published at Lyons in 1673, and at page 118 of the edition of 1727. The oldest is dated 1536. Paul III., without noticing the origin of the ceremony, here says that it is an ancient custom of the sovereign pontiffs to publish this excommunication on Holy Thursday, in order to preserve the purity of the Christian religion, and maintain union among the faithful. It contains twenty-four paragraphs, in which the pope excommunicates: 1. Heretics, all who favor them, and all who read their books. 2. Pirates, especially such as dare to cruise on the seas belonging to the sovereign pontiff. 3. Those who impose fresh tolls on their lands. 10. Those who, in any way whatsoever, prevent the execution of the apostolical letters, whether they grant pardons or inflict penalties. 11. All lay judges who judge ecclesiastics, and bring them before their tribunal, whether that tribunal is called an audience, a chancery, a council, or a parliament.
