Cardinal della Rovere is sent as legate to the Netherlands and France to settle the quarrel concerning the Burgundian inheritance between Louis XI and Maximilian of Austria, to obtain the help of France against the Turks, and to effect the liberation of Cardinal Balue whom Louis had held in strict custody since 1469 on account of treasonable acts.

(1) Louis XI. The name of the cardinal was Jean Balue, whom Louis XI. had persuaded Pope Paul II. to make a cardinal; and later, for political reasons, he had imprisoned him in an iron cage, from which he was liberated in 1481 through the intercession of Pope Sixtus IV. (Trans.)
