Brynolfus, also known as Brynolf Algotsson, was a Swedish Catholic prelate who served as the Bishop of Skara starting in 1278. Born in Västergötland around 1250, he spent twenty years studying in Paris before returning to his homeland. During his leadership, he implemented significant reforms within his diocese and its educational systems. Following a pilgrimage to the Holy Land in 1282, he brought the Crown of Thorns relic to Skara, which became a significant spiritual asset for the region.
