Petra Susser

Petrus Serrarius (Peter Serrarius, Pieter Serrurier, Pierre Serrurier, Pieter Serrarius, Petro Serario, Petrus Serarius; 1600, London – buried October 1, 1669, Amsterdam) was a millenarian theologian, writer, and also a wealthy merchant, who established himself in Amsterdam in 1630, and was active there until his death. He was born "into a well-to-do Walloon merchant family by name of Serrurier in London." He has been called "the dean of the dissident Millenarian theologians in Amsterdam".
He studied at Christ Church, Oxford from 1617 to 1619, and at the Walloon College in Leiden from 1620 to 1623. The French speaking college was then a part of the new Leiden University, where Serrarius met John Dury, and they remained closely associated, right up to Serrarius' own death in 1669.
