Petrus of Skänninge
Petrus of Skänninge († 16th of September 1378), otherwise called Petrus Olavi, Petrus confessor or Petrus dominus was a priest and confessor to St. Birgitta.
Petrus is mentioned in the following passage by Alfonso of Jaén in Epistola solitarii ad reges (III:19).“Alter vero pater spiritualis istius domine erat quidam presbiter de Suecia, virgi eciam venerabilis et sanctissime vite, qui totam domum predicte domine regebat et eam cum filia sua gramaticam et cantum et precepto Christi docuit et in viam virtutum paternalibus correctionibus virtuose corrigendo direxit.” (Edited in: Sancta Birgitta. Revelaciones lib. VIII, p. 56; 'The other spiritual father of this lady was a priest from Sweden, a chaste and venerable man who lived a holy life. He directed the lady’s whole household and, commanded by Christ, taught her and her daughter grammar and chant. He directed them in the life of virtue and virtuously corrected them like a father.' Translation: Dennis Searby 2015, p. 22.)
He is the subject of two vitae, De vita domini Petri Olavi, likely written by Ulf Birgersson in 1426–1427, and Fragmentum de vita et miraculis magistri Petri Olaui by Mathias Laurentii in 1470.
