“ The king was now sixteen, and at this early age he was married to Anne of Bohemia, who herself was only fifteen. She was the daughter of the late Emperor of Germany, Charles IV., called Charles of Luxembourg at the battle of Poictiers, where he attended his father, the old blind King of Bohemia. Anne was thus granddaughter to the brave old blind monarch, and sister to the Emperor Sigismund. As has almost universally been the case with German princesses, there was a great boast and parade of the illustrious ancestry of Anne, but no money whatever. ”
