The labours of the archbishops extended in all directions. Some were zealous pastors of their flocks, such as Jarler and others; some were distinguished canonists, such as Birger Gregerson (1367–83) and Olof Larsson (1435-8); others were statesmen, such as Jöns Bengtsson Oxenstjerna (d. 1467), or capable administrators, such as Jacob Ulfsson Örnfot, who was distinguished as a prince of the Church, royal councillor, patron of art and learning, founder of the University of Upsala and an efficient helper in the introduction of printing into Sweden. There were also scholars, such as Johannes Magnus (died 1544), who wrote the "Historia de omnibus Gothorum sueonumque regibus" and the "Historia metropolitanæ ecclesiæ Upsaliensis", and his brother Olaus Magnus (d. 1588), who wrote the "Historia de gentibus septentrionalibus" and who was the last Catholic Archbishop of Upsala.
