First English edition of the Nuremberg chronicle: being the Liber chronicarum of Dr. Hartmann Schedel…

Rupert (Ruprecht), duke of Bavaria and palsgrave of the Rhine, was elected Roman king in A.D. 1400 by the electors, to succeed Wenceslaus, king of Bohemia, who had been deposed as a worthless man; and he reigned ten years. He was crowned at Cologne by the archbishop there. He was a very Christian man, a lover of righteousness, stern in war, and a conscientious and zealous protector of the downtrodden. Therefore he was confirmed in the sovereignty by Pope Boniface. The Florentines asked Rupert to come to Italy to assist them against the duke of Milan; and for this they promised him a remarkable sum of money, on condition, however, that he was not to receive it until he had reached Milan with his army. In the late fall Rupert went forth, determined to receive the imperial crown from the pope; and in order to collect the promised sum of money he proceeded to the vicinity of Brescia. When he had received part payment, he gave battle to the Milanese; but his forces were dispersed, and he returned to Trent, while the bishop of Cologne and Duke Leopold of Austria, with a large force belonging to King Rupert, returned homeward. From Trent Rupert went through Treviso to Padua. And thence the Florentines sent their messengers, requesting him to resume the war; but since the Florentines offered him less money than he desired, he decided to leave. He sent his expeditionary forces to Treviso by land, while he went to Venice to see the city. There he was honorably and worthily received; and he told the Venetians of his defeat. But, when finally this king received no support from the Venetians nor from the pope, and the Florentines would not satisfy his demand, he returned to Germany without results. By his wife Elizabeth, daughter of the burgrave of Nuremberg, Rupert left many heirs: Rupert and Frederick, his sons, died before he did; but he left him surviving the dukes, Louis, Stephen, John and Otto, and three daughters. One daughter was espoused to Duke Frederick of Austria, on the Etsch; the second, to the count of Cleves, of whom Emperor Sigismund made a duke; and the third, Margaret, was married to the duke of Lorraine. The father and his sons, until their death, remained faithful to Pope Gregory, insisting that the council of Pisa was not properly nor regularly held. Finally, after worthy deeds in the empire and in Germany, Rupert died at Oppenhelm, A.D. 1410; and he lies buried at Heidelberg.

As the schism between Gregory and Benedict (which has already been told to some extent) continued, a long disputation now took place at Florence as to whether a council should be called on account thereof; and the learned men concluded that this could be properly done. The cardinals of both popes, with the consent of the commune at Florence, decided to call a council at Pisa. By letters and messengers they summoned all the bishops, prelates, princes, and the people. To Pisa came a great many people of every nation, and in this council the aforesaid popes were accused and summoned to appear. But Benedict laughed at them in scorn, while Gregory said that the cardinals were powerless to call such a council. However, both popes were finally deposed, and Alexander was elected as above stated. But he did not live in his pontificate for long. As he lay on his deathbed he stated that he believed that the Pisan council was rightfully held and considerately conducted, free of all cunning and risk. And then he died. At that time occurred a great famine and mortality.

At this time came to Pisa, Louis, the duke of Angers, son of the Louis who contested the kingdom with Charles. And he received the kingdom of Apuleia from Alexander; for Ladislaw had done everything by which he might hinder the council.
