Peter's dates of birth and death are unknown, although he lived from the second half of the 13th century until the first half of the 14th century. Initially it was thought he was from Duisburg, Germany, and in some texts he is referred to as "Peter of Duisburg". Other research indicates he may have instead come from Doesburg, the Netherlands.[1]
