De ludo globi (English: The Game of Spheres, The Ball Game, or The Globe Game) is a book by 15th century philosopher, theologian, and cardinal Nicholas Cusanus.
The text was written in Rome and completed in October 1463. It consists of two dialogues, the first between Cusanus and John IV, Duke of Bavaria and the second between Cusanus and John's brother Albert IV, Duke of Bavaria. [1]
This dialogue starts with Cusanus resting after having played a newly invented ball game. "No honest game is entirely lacking in the capacity to instruct," observes Cusanus. Having compared the motion of the misbalanced ball used in the game to the soul of man, set in motion by God, he moves on to discuss a game he had been toying with:
Louis IV, called the Bavarian, of the house of Wittelsbach, was King of the Romans from 1314, King of Italy from 1327, and Holy Roman Emperor from 1328.
The House of Wittelsbach is the Royal Bavarian dynasty from Germany, with branches that have ruled over territories including Bavaria, the Palatinate, Holland and Zeeland, Sweden, Hungary, Bohemia, the Electorate of Cologne and other prince-bishoprics, and Greece. Their ancestral lands of the Palatinate and Bavaria were Prince-electorates, as well as the Archbishopric-Electorate of Cologne, and the family had three of its members elected emperors and kings of the Holy Roman Empire. Their Kingdom of Bavaria was created in 1805 and continued to exist until 1918.
Charles IV, also known as Charles of Luxembourg, born Wenceslaus, was the first King of Bohemia to become Holy Roman Emperor. He was a member of the House of Luxembourg from his father's side and the Czech House of Přemyslid from his mother's side; he emphasized the latter due to his lifelong affinity for the Czech side of his inheritance, and also because his direct ancestors in the Přemyslid line included two saints.
Charles VI, called the Beloved and later the Mad, was King of France from 1380 until his death in 1422. He is known for his mental illness and psychotic episodes which plagued him throughout his life.
Nicholas of Cusa, also referred to as Nicholas of Kues and Nicolaus Cusanus, was a German philosopher, theologian, Catholic cleric, jurist, mathematician and astronomer. One of the first German proponents of Renaissance humanism, he made spiritual and political contributions in European history. A notable example of this is his mystical or spiritual writings on "learned ignorance," as well as his participation in power struggles between Rome and the German states of the Holy Roman Empire.
