[2] Olaus was a student at Uppsala University from its very first semester in 1477 until at least 1486, and later became a monk in the Brigittine Abbey of Vadstena.
He is mentioned as a baccalaureus in artibus in an undated note, and was a magister artium by the time he entered the monastery in 1506.
The manuscripts (C 195, 242, 599, 600, 601, 602 and 627) were edited and published with an introduction by the Latinist Anders Piltz in his dissertation Studium Upsalense (1977).
The notes show a strong emphasis on Aristotelian philosophy and the influence of Albertus Magnus and Thomas Aquinas that pervaded education in all universities in Europe at the time.
His teachers included the theologians Ericus Olai, remembered for his chronicle Chronica regni gothorum, and Peder Galle, who later became known as one of the leading opponents of the Protestant reformation in Sweden.
