(John), archbishop of Upsal, was born at Linconpping in 1488. Being made apostolical nuncio, he used his utmost endeavours to prevent Gustavus Vasa from becoming king of Sweden, and the introduction of Lutheranism into his dominions; and spared no means to attain these ends. He died at Rome in 1545. He wrote a history of Sweden, and a history of the archbishops and bishops of Upsal. He was succeeded by his brother OLAUS MAGNIUS.
