Olaus Magnus

Like his elder brother, Sweden's last Catholic archbishop Johannes Magnus, he obtained several ecclesiastical preferments, among them a canonry at Uppsala and Linköping, and the archdeaconry of Strängnäs.

With the success of the reformation in Sweden, his attachment to the Catholic church led him to stay abroad for good where he accompanied his brother in Poland.

King Sigismund I of Poland offered him a canonry at Poznań and he spent the remainder of his life with the monastery of St. Brigitta in Rome, where he subsisted on a pension assigned him by the Pope.

Olaus had already earlier written Carta marina et Descriptio septemtrionalium terrarum ac mirabilium rerum in eis contentarum, diligentissime elaborata Anno Domini 1539 Veneciis liberalitate Reverendissimi Domini Ieronimi Quirini, which translates as "A Marine map and Description of the Northern Lands and of their Marvels, most carefully drawn up at Venice in the year 1539 through the generous assistance of the Most Honourable Lord and Patriarch Hieronymo Quirino".

[5] The Italian title translates to "A little book, that more closely explains a map of the Nordic cold, beyond the Germanic sea located country, which presents its extremely peculiar, priorly known neither to Greeks or Latins, wonders of nature."
