THE LOCATION OF THE SEATS OF THE ARCHBISHOPS OF TRIER, COLOGNE, AND MAINZ.
In the name of the holy and undivided Trinity, amen. Charles by the grace of God emperor of the Romans, Augustus, and king of Bohemia.... To prevent any dispute arising between the archbishops of Trier, Mainz, and Cologne, electoral princes of the empire, as to their priority and rank in the diet, it has been decided and is hereby decreed with the advice and consent of all the electoral princes, ecclesiastical and secular, that the archbishop of Trier shall have the seat directly opposite and facing the emperor; that the archbishop of Mainz shall have the seat at the right of the emperor when the diet is held in the diocese or province of Mainz, or anywhere in Germany except in the diocese of Cologne; that the archbishop of Cologne shall have the seat at the right of the emperor when the diet is held in the diocese or province of Cologne, or anywhere in Gaul or Italy. This applies to all public ceremonies: court sessions, conferring of fiefs, banquets, councils, and all occasions on which the princes meet with the emperor for the transaction of imperial business. This order of seating shall be observed by the successors of the present archbishops of Cologne, Trier, and Mainz, and shall never be questioned.
THE LOCATION OF THE SEATS OF THE ELECTORAL PRINCES.
1. In the imperial diet, at the council-board, table, and all other places where the emperor or king of the Romans meets with the electoral princes, the seats shall be arranged as follows: On the right of the emperor, first, the archbishop of Mainz, or of Cologne, according to the province in which the meeting is held, as arranged above; second, the king of Bohemia, because he is a crowned and anointed prince; third, the count palatine of the Rhine; on the left of the emperor, first, the archbishop of Cologne, or of Mainz; second, the duke of Saxony; third, the margrave of Brandenburg.
2. When the imperial throne becomes vacant, the archbishop of Mainz shall have the authority, which he has had from of old, to call the other electors together for the election. It shall be his peculiar right also, when the electors have convened for the election, to collect the votes, asking each of the electors separately in the following order: first, the archbishop of Trier, who shall have the right to the first vote, as he has had from of old; then the archbishop of Cologne, who has the office of first placing the crown upon the head of the king of the Romans; then the king of Bohemia, who has the priority among the secular princes, because of his royal title; fourth, the count palatine of the Rhine; fifth, the duke of Saxony; sixth, the margrave of Brandenburg. Then the princes shall ask the archbishop of Mainz in turn to declare his choice and vote. At the diet, the margrave of Brandenburg shall offer water to the emperor or king, to wash his hands; the king of Bohemia shall have the right to offer him the cup first, although, by reason of his royal dignity, he shall not be bound to do this unless he desires; the count palatine of the Rhine shall offer him food; and the duke of Saxony shall act as his marshal in the accustomed manner.
