| Medieval diocese: Strängnäs
Ösmo church, c 50 km from Stockholm and near Nynäshamn was constructed in the beginning of 12th century. In the beginning of 15th century the church was extended and vaulted. Some decades later the vaults were painted. On one of the pillars the name Petr or Peter was found. Previous research (Cornell, Lundberg) has interpreted the inscription as the name of the painter and he should also have painted the churches in Lid and Torshälla. It was also suggested that Peter was the teacher of Albertus Pictor. Anna Nilsén has interpreted an inscription in the church of Lid as “misereri mei alberti pictoris huius eclesie” (Have mercy on me Albert painter of this church). Modern research (Nilsén, Melin) has considered that Albertus Pictor painted even theese churches and Peter never existed.
Many motifs have the painter taken from or inspired of Biblia Pauperum.
