a title of honour given to several princes, and to the principal magistrates of republics. The king of England, the republic and the doge of Venice, and the children of the king of Spain, are called Most Serene: and when the pope, or the sacred college, write to the emperor, to kings, or the doge, they give them no other titles: in like manner the emperor gives no other title to any king, except to the king of France.
